摘要： A swash plate tiltably supported on a drive shaft is controlled by adjusting the pressure in a crank chamber. When an electromagnetic valve is de-excited, the high-pressure refrigerant gas in a discharge chamber is supplied to the crank chamber so that the inclination angle of the swash plate is shifted to its minimum inclination from its maximum inclination. An open/close mechanism located in a suction passage gradually opens or closes the suction passage in accordance with the differential pressure between the pressure in the external refrigeration circuit located upstream the open/close mechanism and the pressure in a suction chamber. When the inclination angle of the swash plate is minimized, the open/close mechanism closes the suction passage. It is therefore possible to prevent frosting while also suppressing rapid changes in load torque.

摘要： A displacement control mechanism for a variable displacement compressor includes a first valve hole, a first valve body, a pressure sensing means operable to sense pressures of first and second points in a discharge pressure region to adjust a position of the first valve body, and a pressure-difference-increasing means operable to increase pressure difference between the first and second points when the pressure of a suction pressure region falls below a predetermined standard pressure. The pressure sensing means displaces the first valve body to increase an opening degree of the first valve hole according to increase of the pressure difference when the first valve hole is part of a supply passage. The pressure sensing means displaces the first valve body to decrease the opening degree of the first valve hole according to the increase of the pressure difference when the first valve hole is part of a bleed passage.

摘要： A compressor has a suction throttle valve, which includes a suction passage, a suction port, a valve body, an urging member, a valve chamber, a first communication hole, a closing valve and a valve seat. The closing valve closes the hole of the valve body by pressure difference between the valve chamber and the suction port. The valve seat limits movement of the closing valve toward the suction port. The hole of the valve body is closed when the closing valve is in contact with the valve body, and open when the closing valve is in contact with the valve seat. A communication passage is formed in the closing valve or the valve seat, which enables communication between the hole of the valve body and the suction port when the closing valve is in contact with the valve seat.
