| description | There is provided a check valve capable of effectively suppressing the generation of chattering. The check valve includes: a housing including an inlet channel, a valve chest, and an outlet channel; a seat member provided around the inlet channel, the seat member including a seat portion; a valve element pressed against the seat portion to close the inlet channel; a biasing member configured to push the valve element toward a valve seat; a guide portion provided at the housing and configured to guide the valve element when the valve element moves in an axial direction; and a damper chamber communicating with the valve chest through a space between the valve element and the guide portion, the damper chamber being configured to attenuate axial moving force of the valve element. The biasing member is arranged in the valve chest. |
