<p>A wobble plate type compressor having a cantilevered drive mechanism is disclosed. The compressor includes a compressor housing (10) having a plurality of cylinders (27) and a crank chamber (14) adjacent the cylinders (27). A reciprocative piston (28) is slidably fitted within each of the cylinders (27). A drive mechanism (15) is coupled to the pistons (28) to reciprocate the pistons (28) within the cylinders (27). The drive mechanism (15) includes a drive shaft (152) which penetrates through an opening (121) of a front end plate (12) and extends into the compressor housing (10). A wedge-shaped cam rotor (151) is attached to an inner end of the drive shaft (152) and rotates therewith. A supporting mechanism (180-183) radially and rotatably supports the drive mechanism (15). The supporting mechanism (180-183) includes a bearing which is located in the cam rotor (151). Therefore, the radial supporting center (C) of the drive mechanism (15) is in close to the point on which the gross gas compression force acts in the axial direction. As a result, a reduction of the life of the bearing is effectively prevented and the defective vibration of the drive mechanism (15) in operation of the compressor is sufficiently reduced without reducing rigidity of the drive mechanism (15). <IMAGE></p> |
