The present application incorporates the following United States Patent Applications by reference in their entireties: U.S. patent application Ser. No. 11/005,887, U.S. patent application Ser. No. 10/118,675, now abandoned, and U.S. patent application Ser. No. 09/861,285. FIELD OF THE INVENTION [0002] The present invention generally relates to the field of oil lubrication devices for compressors, and more particularly to an integrated eccentric flywheel oil slinger suitable for use in oil lubricated air compressors. BACKGROUND OF THE INVENTION [0003] Typically, portable pump devices such as compressors, power washers, and the like include a crankcase or housing encompassing pump components. A gear box often encloses an eccentric, coupled to a drive shaft of the engine or motor powering the pump, for reciprocating a piston in a cylinder. Further, in order to dampen or reduce vibrations caused by any imbalance in the pump mechanism (such as vibrations related to the eccentric's motion) a counter weight and a flywheel may be mounted to the drive shaft. The use of the counter weight and flywheel allows pump vibration to be off-set (such as those caused by piston reciprocation), the overall moment of inertia to be increased and the eccentric to be generally counterbalanced. Additionally, an oil slinger may also be coupled to the shaft to disperse oil from a reservoir or oil sump which is formed in the crankcase or the like for reducing friction and cooling the various pump components. Preferably, an oil slinger is configured to minimize atomization of the oil, account for the pump device being disposed in a non-ideal manner (e.g., disposed on a non-level surface), while providing sufficient lubrication and cooling. [0004] Lower cost oil lubricated air compressors, for example, have employed a "splash" lubrication system to distribute oil from the oil sump to the mechanical bearings, seals, valves, pistons and other parts that require lubrication and oil cooling. A small protruding piece of material or "dipstick" is attached to one or more of the moving components such that during each revolution of the crankshaft, the dipstick dips into the oil sump at sufficient velocity to cause oil to splash onto the components requiring lubrication. The size, shape and velocity of the dipstick must be engineered to assure sufficient lubrication and oil cooling for all components while minimizing atomization of the oil in the crankcase so as to reduce oil loss through the crankcase vent. A higher velocity or larger profile dipstick will improve lubrication and oil cooling but will increase oil atomization and oil loss through the crankcase vent. A less aggressive dipstick velocity or profile will reduce lubrication and oil cooling, but also reduce oil loss through the vent. These conflicting phenomena require designers to compromise their design by reducing the positive benefits of lubrication and oil cooling in order to reduce the negative effects of oil loss. [0005] Additional concerns associated with such traditional splash oil lubrication systems are that a number of the air compressors in which such systems are used are portable and are regularly moved by hand from one work site to another. If such portable air compressors are not properly leveled prior to operation, the dipstick splash lubricator may not reach the oil sump causing a lack of needed lubrication and cooling, possibly leading to subsequent component failure. [0006] Consequently, the foregoing combination of components results in complex assembly and multiple part fabrication which may diminish manufacturing efficiency, require a large number of individual components, require a relatively high level of skill to repair, and the like. Therefore, it would be desirable to provide a pump assembly with a simplified pump component configuration including a lubrication system designed to increase the flow rate of lubricating and cooling oil to lubricated components of an air compressor while reducing oil atomization and oil loss through the crankcase vent. Further, it would be desirable to provide such a lubrication system that is capable of functioning properly while the crankcase is tilted, providing an increased tolerance of operation on non-level surfaces. SUMMARY OF THE INVENTION [0007] Accordingly, the present invention is directed to an integrated eccentric flywheel oil slinger for an oil lubricated compressor crankcase. In a first aspect of the present invention, the integrated eccentric flywheel oil slinger includes a generally cylindrical main body being configured to provide oil to various components of the compressor crankcase and reduce vibrations made by such components. In such embodiment, the generally cylindrical main body includes an aperture for receiving a crankshaft. Further, an eccentric extension protrudes from the generally cylindrical main body and is configured to move about the crankshaft. In addition, the generally cylindrical main body is configured to counter balance the eccentric extension protruding from the generally cylindrical main body and when attached to the crankshaft provides the combined functions of the flywheel, the eccentric, the oil disk slinger and a counterweight. [0008] In further aspects of the present invention, the generally cylindrical main body of the integrated eccentric flywheel oil slinger is configured to counter balance the eccentric extension protruding from the generally cylindrical main body by including apertures or recesses within the generally cylindrical main body. For example, a first aperture in the general shape of a first tear drop which extends through the generally cylindrical main body and a second aperture in the general shape of a second tear drop which extends through the generally cylindrical main body are present to counter balance the mass of the eccentric extension protrusion. Further, in an embodiment, the first aperture is positioned on a first side of the eccentric extension and the second aperture is placed on a second side of the eccentric extension, the second side being generally opposite to the first side. Additionally, the leading edge of the first tear drop providing the first aperture may be formed by the apex of the first tear drop and the leading edge of the second tear drop providing the second aperture may be formed by the base of the second tear drop. [0009] In additional aspects of the present invention, the generally cylindrical main body is partially curved so that the body is concave towards the eccentric extension so that the generally cylindrical main body counter balances the eccentric extension. Further, in an embodiment, the width of the generally cylindrical main body is approximately 0.813 (eight hundred and thirteen hundredths) inches to provide oil to the various pump components. [0010] In another aspect of the present invention, an oil lubricated air compressor assembly is provided. In an exemplary embodiment, the oil lubricated air compressor assembly includes an air storage tank for storing air at a first pressure and an air compressor for compressing air from a second pressure to the first pressure for storage in the air storage tank. In the embodiment, the air compressor includes a cylinder, a piston disposed within the cylinder, a crankcase housing a crankshaft assembly for reciprocating the piston within the cylinder, an oil sump formed in the crankcase for containing lubricating oil for lubricating the cylinder and piston, and an integrated eccentric flywheel oil slinger positioned below the cylinder. The integrated eccentric flywheel oil slinger disk shaped oil may include a generally cylindrical main body being configured to function as a oil disk slinger and a flywheel. Moreover, the generally cylindrical main body includes an aperture for coupling with the crankshaft assembly and an eccentric extension protruding from the generally cylindrical main body being configured to move about the crankshaft assembly. Further, a motor is included for driving the crankshaft assembly for reciprocating the piston within the cylinder. Rotation of the crankshaft assembly by the motor rotates the integrated eccentric flywheel oil slinger for splashing lubricating oil from the oil sump onto the cylinder and piston. [0011] In even further aspects of the present invention, the oil lubricated air compressor assembly, includes a generally cylindrical main body which is configured to counter balance the eccentric extension protruding from such body by including apertures or recesses within the generally cylindrical main body. For instance, a first aperture in the general shape of a first tear drop which extends through the generally cylindrical main body and a second aperture in the general shape of a second tear drop which extends through the generally cylindrical main body are present to counter balance the mass of the eccentric extension protrusion. Further, in an embodiment, the first aperture is positioned on a first side of the eccentric extension and the second aperture is placed on a second side of the eccentric extension, the second side being generally opposite to the first side. Additionally, the leading edge of the first tear drop forming the first aperture includes the apex of the first tear drop and the leading edge of the second tear drop forming the second aperture includes the base of the second tear drop. [0012] In additional aspects of the present invention, the oil lubricated air compressor assembly includes a generally cylindrical main body partially curved so that the body is concave towards the eccentric extension so that the generally cylindrical main body counter balances the eccentric extension. Further, in an embodiment, the width of the generally cylindrical main body is approximately 0.813 inches to provide oil to various components of the air compressor assembly. Moreover, in an embodiment, the air compressor is a direct drive air compressor.
