Claims

[Scope of utility model registration request]

A supply passage from a water inlet, a drainage passage that communicates with the supply passage and sends water taken in from the supply passage to a drainage port, a diaphragm valve that opens and closes a communication port between the supply passage and the drainage passage, and this diaphragm valve. A back pressure chamber formed on the opposite side of the closed surface of It consists of an electromagnetic on-off valve that opens and closes the passage, and by opening and closing the electromagnetic on-off valve, communication between the back pressure chamber and the drainage passage is closed, and by changing the pressure in the back pressure chamber, the diaphragm valve is actuated to open the communication port. In a pilot-type electromagnetic faucet that has a diaphragm valve that opens and closes, the diaphragm valve is made of a diaphragm made of a soft material such as rubber and a rigid body of an appropriate size attached to the diaphragm, in order to increase the rigidity of the diaphragm valve. A pilot type electromagnetic valve having a diaphragm valve, characterized in that the valve support plate is provided with a guide body that slides only in a direction perpendicular to the opening surface of the communication port. Water faucet.
