Claims

[Scope of utility model registration request]

A valve seat that constitutes a fluid flow path, a valve element that moves forward and backward with respect to the valve seat to open and close the flow path, a spring that biases this valve element in the valve closing direction, and a spring that resists the restoring force of this spring. a holding mechanism that holds the valve body in an open state; and a return mechanism that opposes the valve body and presses the valve body in the valve opening direction against the restoring force of the spring when the valve body is returned. The return mechanism includes a return button case, a return button provided in the return button case so as to be able to move forward and backward with respect to the valve body and always biased in the backward direction, and a fluid flow port provided in the return button. a front fluid chamber and a rear fluid chamber partitioned by a partition wall having: a return shaft provided in the front fluid chamber and biased in the forward direction by a biasing spring; When the return button is moved forward by a push-in operation of the return button, the return shaft is held together with the biasing spring and the valve body is pressed in the valve opening direction, and return pressure is continuously applied from the valve body to the return shaft. and an incompressible fluid that escapes into the rear fluid chamber through the fluid flow port and causes the return shaft to retreat.
