Claims

[Scope of utility model registration request]

A communication port is provided in the center of the valve box, and ventilation ports are provided separately on both sides.
A transverse arc-shaped valve chamber is provided on both sides of the tip of a valve seat provided around the communication port, and each one of a transverse arc-shaped inner communication passage and an outer communication passage has a large number of radially arranged guide valves.
A pair is disposed between the communication port and both valve chambers and between both valve chambers and the communication ports on both sides to communicate with each other to form a flow path in the valve box, and A flexible valve leaflet is disposed and covered over the valve chamber, and a valve cover is further provided and covered from above the flexible valve leaflet onto the valve box, and the flexible valve leaflet is communicated with a pilot pressure supply port. A large-capacity switching valve characterized by a configuration with a pilot chamber.
