Claims

[Scope of utility model registration request]

A housing having one end fitted into a sliding hole in the valve body and the other end protruding outside the valve body to which an operating force is applied, and a supply pressure valve formed within the housing and connected to a pressurized air source. A first control pressure chamber is formed adjacent to one end of the housing and is always in communication with a control pressure path connected to a pneumatic device; 1. A return spring is interposed between a supply passage that communicates with a control pressure chamber, a supply valve that is biased by a supply valve spring in the supply pressure chamber to open and close the supply passage, and one end of the housing. Fitted into the sliding hole of the valve body facing each other, the end surface of the sliding part is the first
a first partition member facing the control pressure chamber; a second partition member that is movable and provided between a portion of the first partition member that protrudes from the sliding hole and the valve body; and a protrusion of the first partition member. a second control pressure chamber formed by the second partition member and the valve body and always communicating with the control pressure path; an atmospheric pressure chamber partitioned from the second control pressure chamber by both partition members; and the first partition member. an exhaust passage formed in the first control pressure chamber and the atmospheric pressure chamber, an exhaust valve connected to the supply valve via a connecting rod loosely fitted in the supply passage to open and close the exhaust passage; a control spring that is provided in a chamber and presses both partition members in a direction in which side control pressure in a second control pressure chamber presses both partition members; An air pressure control valve having a third control pressure chamber formed at the other end thereof, and connecting the third control pressure chamber and the control pressure path through a return passage.
