CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority from International PCT Application PCT/US2004/03 1921, entitled "Gas Compressor", filed on Sep. 29, 2004. SEQUENCE LISTING OR PROGRAM [0002] Not Applicable FEDERALLY SPONSORED RESEARCH [0003] Not Applicable TECHNICAL FIELD OF THE INVENTION [0004] This invention is directed to gas compressors. More specifically, the invention is directed to gas compressors wherein the compression is carried out by the action of pistons in cylinders and the pistons are made to reciprocate by being contact with a revolving contoured disk. INDUSTRIAL APPLICABILITY [0005] The gas compressor of the present invention may be used for the compressing of gas for a variety of applications. It may be used to compress coolants for refrigerators and air conditioners. It may be used as a compressor in air pumps for a wide variety of inflatable objects. BACKGROUND OF THE INVENTION [0006] The prior art is replete with disclosures of compressors wherein pistons reciprocate in cylinders and the cause of the reciprocation is the pistons' contact with the surface of a revolving oblique disk, generally called a swash plate. Samples of recent US patents having such disclosures are: U.S. Pat. No. 6,224,349 issued to Iwanami et al May 1, 2001; U.S. Pat. No. 6,302,658 issued to Seipel et al Oct. 16, 2001; U.S. Pat. No. 6,312,231 issued to Kuhne et al Nov. 6, 2001; U.S. Pat. No. 6,318,502 issued to Unger Nov. 20, 2001; U.S. Pat. No. 6,368,073 issued to Kanai Apr. 9, 2002; U.S. Pat. No. 6,390,787 issued to Herder 5/21/20Q2> and U.S. Pat. No. 6,406,271 issued to Valentin Jun. 18, 2002. These compressors share the common features of a rotating motor shaft which rotates a swash plate which has a surface oblique to the axis of the motor shaft. The outer edges of the swash plate are connected to one or more pistons. As the swash plate rotates, the pistons are forced to reciprocate in the pistons and the reciprocal movement of the pistons operates the compressor in a known manner. [0007] Such compressors are prolific in the literature, but not in commerce. These compressors require lubrication, which is undesirable when the compressed gas is to be breathed by a human subject. There is a problem in many of these devices which causes the pistons to be out of line with the cylinders. The rate of speed of the piston in the expansion phase is the same as the rate of speed of the piston in the compression phase. It has been discovered that following compression, it is desirable for the piston to exit the cylinder as quickly as possible. The existing swash plate type compressors do not make provision for the difference in reciprocating speeds. SUMMARY OF THE INVENTION [0008] This invention relates to gas compressors. Gas compressors find a variety of utilities, such as in refrigerators, running pneumatic tools, and supplying air pressure to fill tires and other air-filled devices. The gas compressors of the present invention are run by motors which provide rotary motion. These are preferably electrical motors. The motor shaft is connected to a rotatable disk. [0009] The side of the disk facing the motor is flat and the side of the disk facing away from the motor contains a ramp. This side contains a low area. The height of the disk gradually increases to a peak and then rapidly decreases to the height of the low area. The portion of the disk which is of increased height is hollow so as to maintain a uniform weight throughout the disk. [0010] The air compressor is situated on the opposite side of the motor from the disk and a frame mount connects the motor and the compressor. For the purpose of this description, the motor will be "down" and the compressor will be "up" although any arrangement is possible. Preferably, the compressor contains at least two cylinders and a piston fits into each cylinder. Each piston is attached to a piston rod. The lower end of each piston rod is attached to a roller. Each roller rolls freely along the turning disk and rises and falls as it passes over the ramp on the disk. [0011] The rising and falling motion of the rollers causes alternating up and down motion of the pistons. When the pistons rise, gas in the cylinder is compressed and expelled from the piston. When the pistons fall, a new supply of gas enters the cylinder. [0012] The piston rod passes through a spring. The upper end of the spring attaches to the lower end of the piston and the lower end of the spring attaches to the frame mount. The spring biases the piston rod, causing the piston to be biased toward the lower part of the cylinder. [0013] The compressor contains a self-operated Mower which helps to pre-pressurize air entering the pistons. This blower and an optional fan below the motor serve to keep the compressor from overheating. BRIEF DESCRIPTION OF THE DRAWINGS [0014] The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate the present invention and, together with the description, further serve to explain the principles of the invention and to enable a person skilled in the pertinent art to make and use the invention.
