Title: Variable displacement swash plate compressor
Inventor: ISOGAI YUJI
IPC: F04B27/18
Filed: 2019-03-28
Abstract: To provide a variable displacement swash plate compressor in which a discharge capacity can be quickly restored from a small capacity.SOLUTION: In a compressor of the present invention, a bypass passage 53 connecting a discharge chamber 7b and a suction chamber 7a is formed in a rear housing 7, and an on-off valve 55 is provided in the bypass passage. When a discharge capacity is quickly restored from a small capacity state, the on-off valve 55 opens the bypass passage 53 when the differential pressure between a discharge pressure Pd in the discharge chamber 7b and a suction pressure Ps in the suction chamber 7a is less than a predetermined value, discharges a refrigerant in the discharge chamber 7b to the suction chamber 7a, and then quickly increases the suction pressure Ps. When the differential pressure between the discharge pressure and the suction pressure exceeds a predetermined value, the bypass passage 53 is closed.SELECTED DRAWING: Figure 1
