Abstract

A WOBBLE PLATE TYPE COMPRESSOR IS DISCLOSED WHICH INCLUDES A COMPRESSOR HOUSING (1) HAVING A CRANK CHAMBER (12) AND A CYLINDER BLOCK (11) WHICH IS PROVIDED WITH AN AXIAL CENTER BORE (111) AND A PLURALITY OF CYLINDERS (112). A PLURALITY OF PISTONS (16) ARE SLIDABLY FITTED WITHIN EACH OF THE CYLINDERS (112). A CAM ROTOR (9) IS DISPOSED WITHIN THE CRANK CHAMBER (12) TO ROTATE TOGETHER WITH A DRIVE SHAFT (5).A WOBBLE PLATE (13) IS COUPLED TO THE PISTONS (16) IS DISPOSED ON THE INCLINED SURFACE (91) OF THE CAM ROTOR (9) TO CONVERT ROTATING MOTION OF THE CAM ROTOR (9) INTO RECIPROCATING MOTION TO BE IMPARTED TO THE PISTONS (16) WHILE PREVENTING THE ROTATIONAL MOTION OF THE WOBBLE PLATE (13). A FIRST BEVEL GEAR (6) IS NON- ROTATABLY DISPOSED WITHIN THE CENTER BORE (111) OF THE CYCLINDER BLOCK (11). A SECOND BEVEL GEAR (15) IS FIXED ON THE WOBBLE PLATE (13) AND ENGAGED WITH THE FIRST BEVEL GEAR (6) THROUGH SPHERICAL MEMBER (18) TO PREVENT ROTATING OF THE WOBBLE PLATE (13). THE DRIVE SHAFT (5) EXTENDS WITHIN THE FIRST AND SECOND BEVEL GEARS (6, 15) AND SPHERICAL MEMBER (18), AND IS SUPPORTED ON THE FIRST BEVEL GEAR (6). THEREFORE, THE DRIVE SHAFT (5) IS ROTATED WITHOUT DEFLECTION AND OFFSET, AND VIBRATION AND NOISE IN REDUCTED. (FIG. 1)
