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 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 control valve is located in a variable displacement compressor incorporated in a refrigerant circuit. The control valve controls the displacement of the compressor in accordance with a pressure difference between a first pressure monitoring point and a second pressure monitoring point, which are located in the refrigerant circuit, such that the pressure difference seeks a predetermined target value. An adjusting valve, which is a variable throttle valve, is located in a section of the refrigerant circuit between the first and second pressure monitoring points. The adjusting valve adjusts the restriction amount of the refrigerant in relation to the refrigerant flow in the refrigerant circuit. The compressor displacement is thus optimally controlled.

摘要： Compressor has a driving unit. The driving unit is provided within a crank chamber and decreases the discharge capacity when a control valve opens a control passage to increase the pressure within the crank chamber. The throttle passage delivers oil with the compressed refrigerant to the crank chamber regardless of whether the control valve has opened or closed the control passage. Because the throttle passage may continuously deliver the oil to the crank chamber even when the control valve closes the control passage, the mechanical elements within the crank chamber can be reliably and sufficiently lubricated and the crank chamber is prevented from being in an insufficiently lubricated state.

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.

The pressure difference between two points in a refrigeration circuit is monitored. The pressure difference represents the compressor displacement. The compressor is controlled by a control valve. The control valve operates based on the pressure difference. A controller compares the temperature of the passenger compartment with a temperature setting. If they differ, the controller determines a target pressure difference for the control valve. The controller computes the compressor torque based on the target pressure difference signal. The controller determines a target engine torque based on the compressor torque and controls the engine based on the target engine torque.

摘要： According to the structure for damping the pulsations of discharge pressure of a compressor of the present invention, in the annular discharge chamber 28 divided on the outer circumferential side in the rear housing 5, two bulkhead sections 35 are extended from positions on both sides of the outlet 23 in the circumferential direction in such a manner that they are separate from each other. The end portion of each bulkhead section 35 is extended to halfway between the first discharge port section 20 and the second discharge port section 21. The flow path from the first discharge port section 20 to the outlet 23 is directed to the opposite side to the outlet 23 and then turned back to the outlet 23. Therefore, the length of the flow path from the first discharge port section 20 to the outlet 23 becomes relatively long.
