WIPO Patent Application WO/2016/035730
Kind Code:
A1
Abstract:
[Problem] To provide a compressor that is capable of easily forming a discharge passage connected to a space on the downstream side of a check valve even when there is a restriction on a suction passage.
[Solution] A compressor 100 includes a suction chamber 141, a cylinder bore 101a, a discharge opening 103b, a discharge chamber 142 disposed on the inner side of the suction chamber 141 in the radial direction, a discharge passage 104d, and a check valve 200. The compressor 100 discharges a compressed refrigerant from the discharge passage 104d. The compressor 100 further includes a partition member 160 that is fitted along an inner peripheral surface 104f of a peripheral wall 104b forming the discharge chamber 142 and that divides the discharge chamber 142 in two in the height direction of the peripheral wall 104b, partitioning the discharge chamber 142 into a first space 142a connected to the discharge opening 103b and a second space 142b facing a bottom wall 104a of the discharge chamber 142. The discharge passage 104d is connected to the second space 142b, and when P1 < P2, the check valve 200 closes an opening of a communication unit that communicates the first space and the second space to each other.
