To provide a compressor capable of suppressing the flowing out of lubrication oil in a compressor to the outside of the compressor due to the movement of a refrigerant in a refrigerating cycle caused by a change in temperature in a state where an operation of the compressor is stopped. [Solution] A compressor includes: a housing; a suction region (suction passage 31) and a discharge region (discharge passage 33) which are formed in the housing in a partitioned manner; a shaft which is pivotally supported in the inside of the housing; and a compression mechanism which sucks a refrigerant from the suction region and discharges the refrigerant to the discharge region due to a rotational motion of the shaft, wherein the compressor further includes: a bypass passage 40 which makes the suction region and the discharge region communicate with each other; a valve element 41 which is capable of closing the bypass passage 40 from a discharge region side; and a spring 42 which biases the valve element 41 toward the discharge region side (toward the valve opening direction). |
