Title: Shutting off method for flow water of inlet valve
Inventor: SENOO KATSUMI
IPC: F16K31/163
Filed: 1980-09-12
Abstract: PURPOSE: To reduce the consumption of hydraulic oil energy by applying external force to an inlet valve only when the valve starts opening without self-closing force and before the valve is fully closed without application of the external force at the opened valve having the self-closing force.  
     CONSTITUTION: When an inlet valve 12 continuously closes by its self-closing force and reaches a point to lose its self-closing force, a solenoid 20b is deenergized. Then, a control valve 20 is returned to a neutral position by springs 20c, 20d, hydraulic oil is supplied from a hydraulic oil tank 18 to a cylinder 16, which thus applies external force via a piston 14 to the valve 12, continuing the closing operating of the valve 12 and fully closing the valve. Since the external force is not applied to the valve 12 by the piston 14 with the valve 12 opened with its self-closing force, the consumption of the hydraulic oil energy of the tank 18 can be reduced.
