ABSTRACT:
A wobble plate type compressor is disclosed which includes a compressor housing having a plurality of cylinders and a crank chamber adjacent the cylinders therein. A reciprocative piston is slidably fitted within each of the cylinders. A drive mechanism is coupled to the pistons. The drive mechanism includes a drive shaft which is rotatably supported in an opening of a front end plate and extends into the compressor housing. The drive shaft is supported by a radial bearing. The drive shaft is attached on to an end surface of a cam rotor at an inclindation angle .theta..sub.1 and rotates therewith. The angle .theta..sub.1 is determined so that under severe operating conditions the interior surface of the radial bearing and the exterior surface of the drive shaft are uniformly contacted with each other to prevent damages due to partial contact. In alternative embodiments, the radial bearing is formed with a conical inner surface to insure uniform contact between it and the exterior surface of the drive shaft.
