Claims

[Scope of utility model registration request]

Combines a switch mechanism that automatically stops the pump by moving the valve body against a spring when the internal pressure on the side where air is supplied exceeds a set value, and a safety valve function that automatically releases air. Equipped with a pressure valve switch,
A variable pressure valve switch characterized by being equipped with a knob for adjusting the amount of deflection of the spring.
