Claims

[Scope of utility model registration request]

A valve port that communicates with both chambers is provided in the partition wall that separates the inside of the casing into an inflow chamber and an outflow chamber, and a valve rod inserted through the valve port has an end on the inflow chamber side that is biased toward the valve port. A valve body is provided, and a pressing part is provided at the outer end of the valve stem on the outflow chamber side, and when the pressing part is pushed against the biasing force of the valve body biased toward the valve port, the valve shaft In the operating valve for a flush valve, in which an inflow chamber and an outflow chamber are opened to communicate with each other, the inflow chamber below the valve body is connected to the lower surface of the valve body, and the lower side is opened to the bottom surface in the casing, and the outer peripheral side is inflow. A pressure chamber is formed that remains as a chamber and is divided by a partitioning member and moves up and down with the valve stem, and the partitioning member is provided with a throttle passage that communicates the inflow chamber on the outer peripheral side of the pressure chamber with the pressure chamber. An operating valve for flash valves characterized by the following.
