補正平２．５．３１図面の簡単な説明を次のように補正する。明細書の第１３頁第３行目に「正面図」とある
を「平面図」と訂正する。明細書の第１３頁第３行目に「従来例の開の」
とあるを「従来例の閉の」と訂正する。明細書の第１３頁第６行目に「主弁座」とある
を「主弁体」と訂正する。Amendment 2.5.31. The brief description of the drawing is amended as follows. In the third line of page 13 of the specification, the phrase "front view" is corrected to "plan view." In the 3rd line of page 13 of the specification, there is "Opening of the conventional example"
The statement has been corrected to read ``conventional case closure''. On page 13, line 6 of the specification, the phrase "main valve seat" is corrected to read "main valve body."

Claims

[Scope of Claim for Utility Model Registration] (1) A valve body in which a water inlet and a water outlet are separated by a main valve body and a valve seat, and a pressure chamber that communicates with the water inlet side of the main valve body via an orifice pipe. , a pilot chamber communicating with the pressure chamber through a communication pipe, and a pilot pipe communicating the pilot chamber with a water outlet, a solenoid disposed in the pilot chamber, and driven by the solenoid. A pilot type solenoid valve comprising a pilot valve body that opens and closes a pilot pipe. (2) The pilot type solenoid valve according to claim 1, wherein the solenoid is rotatably fixed to the upper part of the pilot chamber via a packing by a screw provided on the solenoid. (3) A self-holding solenoid is provided that can attract the plunger upward or press it downward and hold it using a permanent magnet and a return spring disposed inside. Pilot type solenoid valve.
