ABSTRACT:
A wobble plate type compressor having a cantilevered drive mechanism is disclosed. The compressor includes a compressor housing having a plurality of cylinders and a crank chamber adjacent the cylinders. A reciprocative piston is slidably fitted within each of the cylinders. A drive mechanism is coupled to the pistons to reciprocate the pistons within the cylinders. The drive mechanism includes a drive shaft which extends through an opening of a front end plate and extends into the compressor housing. A cam rotor is attached to an inner end of the drive shaft and rotates therewith. A support mechanism radially and rotatably supports the drive mechanism. This support mechanism, which is formed within the cam rotor and interfits with the front end plate, includes a bearing located within the cam rotor. Accordingly, the above construction reduces the moment of force acting on the drive mechanism at its radial support center by moving the radial support center closer in the axial direction to the point on the cam rotor at which the maximum gas compression force acts. As a result, the life of the bearing, and the compressor itself, is increased and undesirable vibration of the drive mechanism during operation of the compressor is reduced.
