Brief Patent Description - Full Patent Description - Patent Application Claims
This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 61/015,530, filed Dec. 20, 2007 and U.S. Provisional Patent Application Ser. No. 61/089,810, filed Aug. 18, 2008, each of which is incorporated herein in its entirety. The present disclosure is related to the field of fluid compressors, in particular, fluid compressors used on service vehicles. Air compressors and hydraulic fluid systems are often installed on vehicles used in service industries to provide a source of compressed air or pressurized hydraulic fluid such as is required for air-driven tools or hydraulic power as is required for hydraulic tools and machinery. Notable examples include the heavy equipment industry, the tire service industry and the oil and gas industry among numerous other examples as well known to those skilled in the art. Such vehicles are typically trucks that are adapted for use and particular needs in the various service industries. It is known to install air compressors or power take-off units (“PTO”) for hydraulic fluid systems in the engine compartments of service vehicles where power can be taken from the service vehicle engine to operate the air compressor or hydraulic fluid system. The disadvantage of this arrangement is that the engine of the service vehicle must be left running or idling in order to keep the air compressor or hydraulic fluid system operational. This can result in increased fuel consumption and maintenance costs for the service vehicle as the vehicle engine is typically larger in power capacity than is what is required to effectively operate the air compressor. In addition, the service intervals for the vehicle engine are reduced due to the increased amount of time the engine is left running to operate the air compressor. It is, therefore, desirable to provide an air compressor or hydraulic fluid system for a service vehicle that overcomes these shortcomings and disadvantages. A combination power plant/fluid compressor for a service vehicle is provided. In one embodiment, a small displacement power plant or internal combustion engine can be provided to operate an air compressor hydraulic fluid system. For the purposes of this specification, the term “fluid compressor” is to be interpreted as meaning either an air compressor and/or a compressor or pump for hydraulic fluid systems. In one embodiment, the power plant can comprise a diesel engine. In another embodiment, the fluid compressor can comprise a screw-style air compressor. The engine and fluid compressor can be mounted on a common platform or skid, the platform being mounted on the front or rear of the service vehicle or at any other suitable location on the vehicle. In another embodiment, the engine can be selected to operate on the same fuel as the service vehicle thereby making a separate supply of fuel for the engine unnecessary. In a further embodiment, the engine can be a water-cooled engine that can be coupled to the cooling system of the service vehicle engine. In this embodiment, heated coolant from the engine can be circulated through the service vehicle engine cooling system thereby keeping the service vehicle engine warm and easy to start in, for example, cold weather conditions, In another embodiment, an air conditioner compressor can be operatively coupled to the engine as part of a stand-alone air conditioning system, the system including a condenser unit, a receiver drier and an evaporator unit. The evaporator unit can be installed in the ventilation system of the service vehicle or it can be a portable unit that can be placed in the service vehicle. By placing the evaporator unit in the service vehicle\'s ventilation system, the service vehicle\'s ventilation system blower motor can be used to circulate air cooled by the evaporator in the service vehicle thereby cooling the interior of the service vehicle cool in, for example, warm weather conditions. In another embodiment, the input shaft of the fluid compressor can be directly coupled to mounting means disposed on the end of the crankshaft of the engine. Such mounting means can include mounting tabs on a pulley disposed on the end of the engine crankshaft. In one embodiment, splined receivers can be mounted on each of the mounting tabs on the crankshaft pulley and the input shaft of the fluid compressor. The splined receivers can be configured to receive a splined shaft that can be inserted into each of the splined receivers to directly couple the engine to the fluid compressor. In a further embodiment, the splined shaft can be made of nylon or any other suitable material as well known to those skilled in the art. In another embodiment, the engine can be operatively coupled to a stand-alone electrical charging system comprising an alternator or a generator for use in providing electrical power to the service vehicle and/or charging the battery in the service vehicle to enable the operation of the service vehicle\'s ventilation system blower motor to circulate cooled air in the service vehicle when the stand-alone air conditioning system is provided thereby negating the need to operate the service vehicle\'s engine and to prevent the service vehicle\'s battery being completely drained of power when the stand-alone air conditioning system is being operated. Broadly stated, a combination power plant/fluid compressor is provided for a service vehicle having a fuel tank, comprising: a platform configured for mounting on the vehicle; an engine having a crankshaft operatively disposed on the platform, the engine configured to operate on fuel from the fuel tank; a fluid compressor operatively disposed on the platform; and a coupler operatively disposed between the engine and the fluid compressor, the coupler configured to couple power directly from the crankshaft of the engine to the fluid compressor.
