PROBLEM TO BE SOLVED: To provide a swash plate type variable displacement compressor that can exhibit excellent performance for a long time while reducing the manufacturing cost in a compressor varying a discharge capacity with the usage of an actuator.SOLUTION: A throttle hole 57 is formed at a connection part 133 in a compressor of this invention. The throttle hole 57 is extended from a control pressure chamber 13b side to an inside of an outer sliding part 51c. In this compressor, refrigerant gas is discharged from the inside of the control pressure chamber 13b to a swash plate chamber 25 through the throttle hole 57 in addition to each opening adjustment of a high pressure passage 15b and a low pressure control valve 15c when adjusting a pressure in the control pressure chamber 13b. Lubricating oil is discharged together with the refrigerant gas from the throttle hole 57. Thereby, in the compressor, the lubricating oil is hardly stored in the control pressure chamber 13b, and shortage of the lubricating oil in the swash plate chamber 25 hardly occurs. |
