Title:
CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2021/054139
Kind Code:
A1
Abstract:
A control valve (CV) according to the present invention includes: a second inner circumferential portion (E112) capable of holding a first spring (SP1), in a first communication passage (E11) provided at a first discharge opening (E1) of a housing (1); and a recessed portion (E113) recessed in a radial direction, at a position that is a part of a region in a circumferential direction of the second circumferential portion (E112) and overlaps a second communication passage opening (E13) in a biasing direction of the first spring (SP1). Therefore, when inserting the first spring (SP1) into the first communication passage (E11), it is possible to hold the first spring (SP1) with the inner circumferential surface of the second inner circumferential portion (E112). Consequently, the first spring (SP1) is appropriately mounted in the second circumferential portion (E112), thereby preventing a mounting defect of the first spring (SP1).
