ABSTRACT:
An air conditioning refrigerant compressor assembly includes a swash plate disposed on a drive shaft centrally within a housing. Three double-ended pistons are reciprocally supported on the swash plate within respective front and rear compression chambers. A pulley is freely rotatably supported concentrically about the drive shaft and connected by a flexible endless driving belt to a power take-off of an engine. A hub is fixedly retained on the end of a drive shaft. An annular torque cushion made of an elastomeric material is bonded to the hub and extends radially outwardly therefrom to support an outer ring concentrically about the drive shaft. An armature plate is fastened to the outer ring. An electromagnetic solenoid creates a field of magnetic flux when energized which draws the armature plate into frictional engagement with the pulley causing the rotary motion of the pulley to be transferred to the drive shaft which rotates the swash plate within the housing. The torque cushion has a tapering axial thickness decreasing steadily from a maximum thickness adjacent the hub to a minimum thickness adjacent the outer ring.
