- the high pressure fluid filled in the chamber 112 is discharged through the orifice 86, and the fluid filled in and outside the chamber 112 and the upper plunger 90 is in a low pressure state.
- the pressure inside and outside the upper plunger 90 is the same by the pressure passages 130 and 132 formed in the upper plunger 90 when the upper plunger 90 moves in a straight line.
- the movement is smooth.
- the high pressure fluid filled in the lower portion of the lower plunger 58 is delayed from moving to the upper portion of the lower plunger 58 by the delay ring 152.
- a pressure difference is generated between the upper part and the lower part of the valve, and the pressure difference causes the lower plunger 58 to move before the movement according to the electrical signal of the coil 54, thereby opening the outlet 68 of the valve seat 52. do.
- the lower plunger 58 is moved by the pressure difference between the upper and lower portions before the force pulled by the upper plunger 90 by the electrical signal of the coil 54 acts on the lower plunger 58. 58) smooth movement and valve operation can be performed smoothly.
- the present invention is a fluid control valve is installed in a high pressure vessel in which the raw material gas of the hydrogen fuel cell system is installed to control the flow of the raw material gas when filling the raw material gas into the high-pressure container, when supplying the raw material gas stored in the high-pressure container to the gas using unit
- the operation of the valve can be made smoothly, and the valve can be prevented from being broken by the pressure of the fluid.
