VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/090638
Kind Code:
A1
Abstract:
This valve device is provided with a case member (10, 60), a valve body (30), a sleeve (43, 44, 45), a spring (481, 482, 483), and a spring end support part (65, 66, 67). The sleeve is slidably supported by the inner wall of a fluid inflow part (651, 652, 653) of the case member, and forms a flow path through which a fluid flowing out from a valve outflow port (373, 374, 375) of the valve body is guided toward a fluid outflow port (61, 62, 63) of the case member. The spring is disposed so as to surround the outer circumferential surface of the sleeve, and biases the sleeve toward the valve body. The spring end support part is formed, in the case member, at an end of the spring on a side opposite to the valve body side, and supports the axial end of the spring on the side opposite to the valve body side from radially outside of the spring.
