Claims

[Claims for Utility Model Registration] (1) A valve cylinder having a fluid inlet and a fluid outlet, a main valve configured to be slidable within the valve cylinder, and abutting against the main valve, a piston configured to be slidable; a spring means for pressing the main valve so that the main valve closes or communicates with the fluid inlet and the fluid outlet; A solenoid valve for fluid control, comprising: a fluid supply section that supplies fluid to the piston so as to slide in a reverse direction; and a solenoid device that closes or opens the fluid supply section. (2) The solenoid device includes a pilot valve that closes and opens the fluid supply section by contacting the fluid supply section and separating from the fluid supply section, and when the fluid supply section is closed, the pilot valve closes and opens the fluid supply section. 2. The fluid control solenoid valve according to claim 1, wherein the pressure of the fluid supplied from the fluid supply section is applied to a side surface of the pilot valve. (3) The pilot valve has a through hole, and the through hole discharges the fluid that presses the piston when the fluid supply section is closed by the pilot valve, and discharges the fluid that presses the piston when the fluid supply section is opened. 3. The fluid control solenoid valve according to claim 2, wherein the fluid control solenoid valve stops discharging the fluid that flows further into the valve.
