<p>PROBLEM TO BE SOLVED: To provide a check valve in which a valve seat member and a housing that are assembled hardly come off in service, thus resolving drawbacks of a compressor, a cooling circuit and a vehicle. SOLUTION: This check valve is composed of a valve seat member 70, a housing 71, a valve element 72 and a spring 73. In this case, a recess 70c of the valve seat member 70 and each projection 71a of the case 71 are prevented by each flange 71g of the case 71 from slipping off. Each flange 71g is fan- shaped, pairing off with the other and is positioned only in the outer part of the projection 71a, abutting against the inner wall of a storage chamber. The thickness of each flange 71g includes the thickness of the projection 71a, and the outer face of the flange 71g is flush with the outer peripheral face of a main body part 70a of the valve seat member 70.</p> |
