Claims

[Scope of utility model registration request]

A supply valve seat and an exhaust valve seat are formed opposite to each other in a valve body equipped with a supply port, an output port, and an exhaust port,
The supply valve and exhaust valve bodies that open and close these valve seats are each biased in the valve closing direction by springs, and a rod inserted through these valve bodies is inserted between the pair of valve bodies in the axial direction of the rod. A protrusion is provided that selectively engages one of the valve bodies to open the valve when the valve body is in the vertical position, and one end of the rod is connected to a pressure receiving body that can be positioned vertically in the axial direction to partition a reference pressure chamber and a feedback chamber. The feedback chamber is isolated from the back chamber behind the exhaust valve body in a non-communicating state and communicated with the output port through a static pressure hole, and the back chamber is connected to a dynamic pressure hole provided in the exhaust valve body. 1. A pressure control valve, characterized in that it communicates with an output port through a hole and is provided with means for urging a pressure receiving body in a reference pressure chamber with a set force.
