摘要： A variable displacement compressor that decreases displacement to reduce compression load without imbalancing the rotation of the drive shaft when the rotating speed of the compressor's drive shaft exceeds a predetermined limit value. The compressor includes a pressurizing passage connecting a crank chamber to a discharge chamber. A rotated guide rotates integrally with the drive shaft. The pressurizing passage is opened and closed by a valve body. Orbiting balls, which contact the valve body, are arranged about the axis of the drive shaft and the rotated guide. The balls follow the rotation of the rotated guide and orbit about the axis. The orbiting radius of the balls varies. A spring urges the balls in a direction decreasing the orbiting radius of the balls. When the rotating speed of the drive shaft exceeds the limit value, centrifugal force moves the balls against the force of the spring and increases the orbiting diameter of the balls. This moves the valve body and increases the size of the pressurizing passage.

摘要： A single-headed piston type swash-plate compressor has a cylinder block having cylinder bores in which a plurality of pistons are slidably received. A first housing is attached to a first end of the block to form a crank chamber therebetween, and a second housing is attached to a second end thereof to form an annular suction chamber and a central discharge chamber therebetween. The chambers are partitioned by an annular wall portion projected from an inner wall of the second housing such that the suction chamber surrounds the discharge chamber. A drive shaft rotatably is extended through the crank chamber, and a conversion mechanism is provided on the shaft for converting a rotating movement of the shaft into a reciprocating movement of each piston in the corresponding bore such that a suction stroke and a discharge stroke are alternately executed therein. During the suction stroke, a fluid is introduced from the suction chamber into the bore, and during the compression stroke, the introduced fluid is compressed and discharged from the bore into the discharge chamber. The cylinder block has a portion extended radially and outwardly from a side thereof, and the portion has a damping chamber formed therein. The discharge chamber has an elongated portion extended radially and outwardly therefrom, the elongated portion being in communication with the damping chamber through a small passage formed in the extended portion of the block.

摘要： In a swash-plate compressor, pistons are slidably received in cylinder bores. A drive shaft is extended through a crank chamber, and is rotated through an electromagnetic clutch means associated therewith. A conversion mechanism is provided on the shaft for converting a rotational movement of the shaft into a reciprocation of each piston in the corresponding cylinder bore such that a suction stroke and a discharge stroke are alternately executed therein. A fluid is introduced from a suction chamber into the bore during the suction stroke, and during the compression stroke, the fluid is compressed in and discharged from the bore into a discharge chamber. The conversion mechanism is constituted such that a stroke length is shortened in response to an increase of a pressure in the crank chamber, and vice versa. A first passage communicates the crank with the suction chamber, and a second passage communicates the crank chamber with the discharge chamber. A control valve is provided in one of the first or second passage, and is magnetically actuated by the clutch for controlling the pressure in the crank chamber such that the piston stroke can be minimized whenever the clutch is electrically deenergized.
摘要翻译：在斜盘式压缩机中，活塞可滑动地容纳在气缸孔中。驱动轴通过曲柄室延伸，并且通过与其相关联的电磁离合器装置旋转。在轴上设置有转换机构，用于将轴的旋转运动转换成相应气缸孔中的每个活塞的往复运动，从而在其中交替执行吸入冲程和排出冲程。在抽吸行程期间，将流体从吸入室引入孔中，并且在压缩行程期间，流体被压缩并从孔排出到排出室中。转换机构被构造成使得响应于曲柄室中的压力的增加而缩短行程长度，反之亦然。第一通道将曲柄与抽吸室连通，第二通道将曲柄室与排出室连通。控制阀设置在第一或第二通道中的一个中，并且由离合器磁力驱动以控制曲柄室中的压力，使得每当离合器被电断电时活塞冲程可以最小化。

摘要： A variable displacement compressor adjusts the pressure in a control pressure chamber and controls the displacement in accordance with the adjusted pressure. Refrigerant is supplied via a supply passage, and released via a bleed passage. The compressor includes a first control valve for adjusting the cross-sectional area of the supply passage for refrigerant. The compressor further includes a second control valve that adjusts the cross-sectional area of the bleed passage in accordance with the opening/closing state of the first control valve. The second control valve adjusts the cross-sectional area of the bleed passage such that the cross-sectional area when the first control valve is in the closed state is larger than that when the first control valve is in the opened state. The back pressure chamber is located in a section of the bleed passage that is located between the second control valve and the control pressure chamber.
