Abstract
An automobile vehicle air conditioning compressor adapted to be driven by a vehicle engine crankshaft through a drive pulley torque transfer mechanism wherein an electromagnetic clutch engagement plate is carried by the pulley and wherein a companion friction disc of an electromagnetic clutch is journalled on the compressor housing, the pulley being journalled on the compressor drive hub at a location axially spaced from the electromagnetic clutch thereby permitting the diameter of the clutch to be varied as desired.
Claims3
A compressor for compressing refrigerant gas in an air conditioning system for a vehicle having an engine comprising a compressor housing, pumping elements in said housing, said housing having a flow inlet port and a flow delivery port, said pumping elements being adapted to compress refrigerant gas received through said inlet port and to discharge compressed refrigerant gas through said delivery port;
- a bearing support sleeve located on said housing, a bearing support member having a radial clutch plate joined thereto, electromagnetic clutch coil windings carried by said housing adjacent said clutch plate;
- first bearing means for journalling said bearing support member on said sleeve;
- a drive pulley located in axially spaced relationship with respect to said clutch plate;
- a clutch actuator plate connected to said pulley and located between said pulley and said clutch plate, said actuator plate having a resilient connection to said pulley;
- a torque input driveshaft extending through said sleeve and being connected to one of said pumping elements, said driveshaft being drivably connected to said bearing support member;
- and
- second bearing means for journalling said drive pulley on said bearing support member.
