Abstract: A swashplate (24) is mounted to a drive shaft (7) so that it is able to tilt, and a driving hub (20) pivots on the shaft (7) and has a projection section (20c) which extends through the swashplate (24). Mountings (26,27,28;60,70) secure the hub (20) so that it can rotate with and at the same time position itself at an angle to the shaft (7). A bearing (23) is located between the swashplate (24) and the projection (20c) of the driving hub (20). The hub projection (20c) has an external thread (20e) which meshes with an internal thread (28b; 60a, 70a) on the mounting members (26, 27, 28; 60,70). When the threads are screwed home, the bearing (23) is forced against the swashplate (24). ADVANTAGE - Improved swashplate mounting reduces compressor vibration and noise and extends bearing and component life.

Abstract: PURPOSE:To cut off a communicating passage securely so as to maintain a small capacity operation, and to prevent a sudden rise of the torque by providing an electromagnetic valve at the downstream of a control valve in the communicating passage between a crankcase and a suction chamber. CONSTITUTION:At a communicating passage 16 between a crankcase 6 which houses an oscillating plate 50 installed to a rotary shaft 7, and a suction chamber 15, a valve chamber 18 is provided. And a control valve 19 to open and close the communicating passage 16 according to the suction air pressure is provided to the valve chamber 18, and thereby the pressure in the crankcase 6 is regulated so as to convert the inclination of the oscillating plate 50. In such a constitution, an electromagnetic valve 28 provided at the downstream of the control valve 19 is closed by an electromagnetic control device 38, at the same time when a compressor is started to operate, so as to cut off the communicating passage 16. And the escape of a coolant gas in the crankcase 6 to the suction chamber 15 is blocked, and the oscillating plate 50 is maintained at a small capacity angle. Consequently, the small capacity operation is maintained, and a sudden rise of the torque is prevented.

Abstract: PURPOSE:To reduce the noise generated by the vibration of an oscillating plate and improve durability by eliminating this vibration. CONSTITUTION:A recessed part 24a is provided at the inner peripheral edge of an oscillating plate 24, and an angular ball bearing 23 is force-fitted into the recessed part 24a. The oscillating plate 24 is fitted to the boss part 20 of a drive hub 20 through the ball bearing 23, and a male screw 20e is formed at the outer periphery of the boss part 20c of the drive hub 20. A lock nut 28 is screwed into the boss part 20c through a balance weight 26 and a lock washer 27, and the butt-contact part 26b of the balance weight 26 is butt-pressed to one end face of the inner wheel 39 of the angular ball bearing 23. When one end face of the inner wheel 39 of the angular ball bearing 23 is pressed, axial and radial forces act upon a ball 40 since the inner peripheral surface of the inner wheel 39 is inclined, and an outer wheel 41 is also pressed axially and radially since the inner peripheral surface of the outer wheel 41 is also inclined so as to eliminate a gap with the oscillating plate 24.

Abstract: PURPOSE:To suppress a torque variation and to avoid a liquid contraction by providing a capacity control valve with a relatively large opening area in one side of plural passages communicating a crankcase and a suction chamber, and cutting off the passage when the pressure in the crankcase is made lower than a specific value. CONSTITUTION:In a communicating passage 16 between a crankcase 6 housing an oscillating plate 50 installed to a rotary shaft 7, and a suction chamber 15, a valve chamber 18 is provided. And a control valve 19 to open and close the communicating passage 16 according to the suction air pressure is provided to the valve chamber 18, and thereby the pressure in the crankcase 6 is regulated to convert the inclination of the oscillating plate 50. In such a constitution, the second communicating passage 39 to communicate the both chambers 6 and 15 is added, and a capacity control valve 27 which is closed when the pressure in the crankcase 6 is lowered less than a specific value is provided therein. And the opening area of the capacity control valve 27 is made larger than that of the control valve 19. Furthermore, an orifice 29 is provided at the discharge side end of the second communicating passage 39 to throttle the passage.
