Abstract
Compressor apparatus 10 comprises an air compressor 12 driven by a crankshaft 23 of a vehicle engine 20. The compressor 12 is typically an integral oil flooded screw machine driven via a pulley 30 and a tensioned belt 22 which is additional to a fan belt. Since a prop shaft is not used to drive the compressor 12, the apparatus 10 may be used in front wheel drive or in rear wheel drive vehicles. It may be connected to tyre inflation equipment via an air outlet 16 and may be selectively powered via a clutch 32. Outlet air pressure is regulated by control means 40. Air is typically compressed to 2 to 14.2 bar and flows at 2.25 cubic metres per minute.
Description
Improvements in and relating to Compressors
Field of the Invention
The present invention relates to compressor apparatus, a vehicle comprising compressor apparatus and a method of driving compressor apparatus.
Background to the Invention
Air compressors may be provided in adapted specialist vans, for example vehicle repair vans. Such compressors are used to power pneumatic tools and, in particular, air jacks for quickly and easily raising vehicles off the ground. These prior art air compressors are driven by the prop shaft which usually delivers the drive to the rear wheels of the vehicle. Accordingly, in order to use air compressor whilst the vehicle is stationery the prop shaft must include a separation portion to disengage the drive being transmitted to the rear wheels. This, therefore, requires major alteration to a standard vehicle and is expensive. In addition, the resale value of the vehicle may be reduced due to the alteration. Furthermore, transmission of the drive to the rear wheels may be effected and such vehicles may have an increased risk of failure.
Such prior art compressors for vehicles cannot be used with front wheel drive vehicles since, there is no accessible prop shaft with which to drive the air compressor.

Figure 1 is a schematic drawing of an embodiment of compressor apparatus.
Figure 2 is a schematic drawing showing an embodiment of an auxiliary drive belt.
Figure 3 is a front view of an embodiment of compressor apparatus.
lo Figure 4 is an end view of an embodiment of compressor apparatus.
Description of the Preferred Embodiments
As shown in Figure 1, an embodiment of the compressor apparatus 10 comprises an air compressor 12. The air compressor 12 is an industrial oil flooded screw machine specially modified for automotive applications in order to accept a close coupled gearbox or gear set which is compact and is easily accepted within the confined engine space. In addition, the gearbox is arranged to be engaged with a standard pulley including a standard centre distance in order to be driven by a standard drive belt.
Accordingly, such equipment is readily available as spare parts. The air compressor 12 comprises an air inlet 14 and an air outlet 16. The air inlet 16 has an opening which is located in the engine bay but may be located at any suitable position. The air inlet includes an air filter and also a valve. The valve is a close coupled inlet valve which is arranged to shut the air supply to the compressor down if required, for example, when there is a condition where the demand for compressed air is achieved. The air outlet 14 includes a pipe which extends À À À ee.
À À À À À À - À À À À À À À À ee e.e e - to a port (not shown). The port enables the supply pipe from any air powered tool or pneumatic equipment to be engaged therein in order for the air compressor 12 of the compressor apparatus 10 to power the air powered tool.
The port or outlet cock is located at a side or rear of the vehicle but may be located at any suitable position.
The port incorporates a shut off valve.
In one embodiment, the compressor apparatus 10 is mounted lo in a vehicle recovery vehicle and the air compressor 12 provides power to a pneumatic jack. The air compressor 12 may also be used to power an impact gun which may be used to remove road vehicle wheel securing nuts on commercial and/or private cars and/or light commercial vehicles.
Furthermore, the air compressor 12 may provide the pneumatic power for the inflation of Lyres on commercial and/or private vehicles. The compressor apparatus 10 may be mounted on a vehicle in order to power any other compressed air implement, for example to provide pneumatic power for the use of ground and asphalt breaking tools in the utility sector.
The air compressor 12 is directly powered by the crank shaft of the vehicle engine 20 through a belt 22 and preferably through the auxiliary drive belt 22 for example a drive belt additional to a conventional fan belt. As shown in Figure 1 and Figure 2, an auxiliary drive belt 22 may already be present on the vehicle to power other components on the vehicle, for example air conditioners, vehicle alternator 24, power steering pump 26 etc. However, the conventional auxiliary drive belt may have to be replaced by a new auxiliary drive belt 22 in order to accommodate the extra pulley 30 to power the air À-. e ae.
À À À À À he e.,. e.e compressor 12. The auxiliary drive belt may also extend around an automatic tensioner pulley 28 and an idler pulley 29.
The auxiliary drive belt 22 is driven by the crank shaft 23 of the vehicle engine 20. Movement of the auxiliary drive belt 22 causes rotation of the air compressor pulley 30. As shown in Figure 1 and Figure 3, the air compressor 12 includes a clutch 32 in order for the drive from the lo auxiliary drive belt 22 to be selectively transmitted to the air compressor 12. The clutch 32 is a magnetic clutch 21 which is controlled by control means 40. The control means 40 is electrically operated and enables the user to turn the power on and off to the air compressor 12. The control means 40 also controls the pressure of the air supplied by the outlet and may also control the volumetric flow rate. However, the flow rate may be set depending on the application of the compressor apparatus 10. In addition, the control means may also automatically stop the air compressor 12 if the pressure falls below a critical level or if no air is being supplied.
The air compressor uses an increased idle regime in the range of 1500 to 2500 rpm. The control means 40 incorporates a pneumatic or electric speed device in order to speed the engine up when the compressor apparatus 10 is operable.
The magnetic clutch 32, when engaged, drives a shaft which extends to a gear set 34. The gear set 34 then variably transmits the drive to the air compressor 12.
À À À e e.
À À À À . Àe. .-e À À . À . À À . À .- À À - À Accordingly, the air compressor 12 is driven by the crankshaft 21 of the vehicle engine 20 through the auxiliary drive belt 22. The compressor apparatus 10 can be quickly and easily fitted to existing vehicles and can be quickly and easily removed if no longer required. In addition, since the prop shaft is not used to drive the air compressor, the compressor apparatus can be used with either rear wheel or front wheel drive vehicles.
lo As shown in Figure 1, Figure 3 and Figure 4, the compressor apparatus 10 includes mounting means in the form of a bracket 18. The bracket 18 is provided on the rear of the air compressor 12 and is secured to the vehicle engine 20 by screw fasteners or by any other suitable means. In particular, the air compressor 12 may be mounted at a location where major motor manufacturers usually locate an air conditioning unit although other suitable locations may be used.
The compressor apparatus 10 is capable of delivering up to cubic feet per minute or up to 2.25 metres cubed per minute (m3minl) of compressed air at pressures in the range of 2 to 14.2 bar or 25 to 205 psi.
The compressor apparatus 10 does not effect or interfere with the actual transmission of power to the vehicle wheels and can be easily fitted to existing vehicles.
