    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 displacement control valve for a compressor is provided. When current to a coil is stopped due to, for example, a broken wire, the control valve prevents the load acting on a variable displacement compressor from becoming excessive. A suction chamber is connected to a crank chamber by a control passage. A bellows actuates a valve body in accordance with the pressure in a suction chamber thereby regulating the opening size of the control passage. The compressor displacement is varied accordingly. A solenoid varies the attraction between a plunger and a fixed core in accordance with the level of current supplied to a coil thereby changing a target pressure. The bellows is actuated based on the target pressure. The solenoid increases the target pressure as the current to the coil is decreased. When the current to the coil is stopped, the solenoid maximizes the target pressure.

    摘要: A variable displacement compressor the displacement of which is externally controlled is provided. The compressor has basically the same structure as prior art compressors except for simple differences. A pressure sensing chamber of a displacement control valve is connected to a suction chamber by an outlet passage. A bellows is located in the pressure sensing chamber. The bellows expands and contracts in accordance with the pressure in the sensing chamber. A valve chamber forms part of a displacement control passage, which is used to control the pressure of a crank chamber. A valve body is located in the valve chamber. The valve body is moved by the bellows to open and close the displacement control passage. Highly pressurized gas from the discharge chamber is supplied to the pressure sensing chamber through an inlet passage. The gas in the pressure sensing chamber is released to the suction chamber through the outlet passage. An electromagnetic valve is located in the outlet passage to regulate the flow of refrigerant gas from the sensing chamber. The outlet passage also includes a bypass passage. The bypass passage bypasses the electromagnetic valve and constantly communicates the pressure sensing chamber with the suction chamber.

    摘要: A compressor includes a discharge chamber and a retaining passage, which is located downstream of the discharge chamber. A control valve controls the displacement of the compressor in relation to the pressure difference between a first pressure monitoring point in the discharge chamber and a second pressure monitoring point in the retaining passage. A pressure introducing passage connects the retaining passage to the control valve. The pressure introducing passage has an opening to the retaining passage. An inlet member is located in the retaining passage to cover the opening. The inlet member has a pressure introducing port that functions as the second pressure monitoring point. The pressure of the refrigerant in the retaining passage is supplied from the pressure introducing port to the control valve through the pressure introducing passage. The inlet member easily alters the position of the pressure introducing port in the retaining passage.

    摘要: A valve housing has a communication passage communicating a suction port of the compressor with a crank chamber of the compressor. A valve element opens and closes the communication passage, and a spring member resiliently biases the valve element toward the closed position. A pressure actuated unit moves the valve element toward the open position by a suction pressure of the compressor. The spring member includes a spring made of a temperature responsive material. The spring decreases in its resilient force in an opening direction of the valve element with increase of an outer-air temperature. The spring member has a primary spring made of an ordinary resilient material for resiliently biasing the valve element toward the closed position and a correction spring made of a material having a temperature positive characteristic. The correction spring provides a correction spring force smaller than a primary force of the primary spring in the opposite direction to the primary force. The combined spring force of the primary spring and the correction spring acting on the valve element.

    摘要: A compressor having a device for recovering lubricating oil. The compressor includes a discharge chamber and a muffler, which attenuates the pressure pulsation of refrigerant gas sent out from the discharge chamber. The muffler is defined by a muffler base, which is formed on the cylinder block, and a muffler cover, which is attached to the muffler base. The muffler includes a first muffler chamber and a second muffler chamber, which are connected by an opening. The muffler cover has a gas outlet for sending the refrigerant gas out of the compressor from the second muffler chamber. Lubricating oil separated from the refrigerant gas in the first muffler chamber is sent to the crank chamber through a recovery passage. The location of the gas outlet can be easily changed by replacing the muffler cover. Thus, the compressor can be easily adapted to different engine compartments.
