Title:
FLUID CONTROL VALVE
Document Type and Number:
Japanese Patent JPH0276902
Kind Code:
A
Abstract:
PURPOSE: To improve the performance of the valve by providing a discharge port and an obturator capable of being moved so as to abut on the discharge port and move away from it.
CONSTITUTION: A pilot port 12 is connected to a discharge port 15 controlled by an obturator 16 capable of moving toward or away from the discharge port 15. The discharge port 15 has an orifice having a larger cross-sectional area than the cross sectional area of an orifice of a control orifice 14. When the obturator 16 is separated enough from the discharge port 15, the pressure in the pilot port 12 efficiently drops to zero. Thus, the performance of the fluid control valve is improved.
