Claims

[Scope of utility model registration request]

A valve body with a main valve body and a valve seat separating a water supply port and a water spout, a pressure chamber that communicates with the water supply port side of the main valve body via an orifice pipe, and a pressure chamber that communicates with the pressure chamber via a communication pipe. a pilot chamber, and a pilot pipe communicating the pilot chamber and the water outlet,
A solenoid is disposed in the pilot chamber, a plurality of sliding pieces are protruded from a plunger body that slides within the solenoid in parallel with the sliding direction, and a pilot valve body is provided on the plunger body for opening and closing the pilot pipe. This is a pilot type solenoid valve.
