Check valve with vibration prevention function for valve body |
摘要 |
A transmission member that transmits urging force of a helical spring to a valve body is disposed between the valve body and the helical spring. The transmission member changes a direction of an urging force transmitted to the valve body such that the urging force is oblique to a pressure action direction X. Accordingly, when a check valve is in an open state, the valve body is pressed against a side wall and thus vibration of the valve body is inhibited. Further, when the check valve is in a closed state, an angle theta formed by the direction of the urging force transmitted to the valve body and the pressure action direction X is set to be between 8 degrees and 45 degrees. Accordingly, it is possible to simultaneously realize a fluid path opening/closing function and a valve body vibration inhibition function.
