Claims

[Scope of utility model registration request]

Hydraulic pressure responsive pneumatic control in which a valve body is slidably fitted into a valve body, and the valve body controls the opening degree of a valve passage communicating between two valve chambers divided by a partition wall. In the valve, a cylinder chamber is formed in the valve body, a piston is slidably fitted into the cylinder chamber in the same direction as the sliding direction of the valve body, and the cylinder chamber is connected to the cylinder chamber through a hydraulic pressure introduction hole. The valve body is divided into a hydraulic action chamber into which hydraulic pressure is introduced and an atmosphere introduction chamber which communicates with the atmosphere through a throttle hole, and the valve body is made to protrude into the atmosphere introduction chamber and the valve body is moved in a direction away from the valve body. A hydraulic response air control valve characterized by inserting a spring that presses a piston.
