Claims

[Claims for Utility Model Registration] Two valves provided in each of the bodies are alternately opened and closed by displacement of a pressure element sandwiched between the two bodies, and the output connected to each of the valves is increased or decreased in one direction. In contrast, in a double-acting pilot relay in which the other valve is increased or decreased, a supply seat provided to partition the supply side and the output side of one of the valves is supported by an elastic member that is cantilevered on the body. A pilot relay that is characterized by:
