Title: Three-way fluid control valve with check valve
Inventor: HAMAMOTO SATOSHI
IPC: F16K31/06
Filed: 1992-11-06
Abstract: PURPOSE:To provide stable action with no misoperation against an abnormal rise of pressure by eliminating a sliding part, and forming a so-called structure strong against dust, in a fluid control valve provided with a check function for preventing a reverse flow from a load port to a pressure supply port in a 3-port 2-position valve. CONSTITUTION:In the case of non-excitation of a solenoid 30, a fluid flows in from a pressure supply port (a), but a steel ball 10 is pressed to a seat 7 by a supply pressure to close a flow path, and another steel ball 11 is pressed to a side of a fixed core 15. As a result, a load port (b) and a return port (c) are placed in a communication condition. Next by exciting the solenoid 30, when a movable core 19 is attracted, the steel ball 11 is pressed to the seat 7 through a push rod 18, to close the return port (c). Simultaneously by displacing the other steel ball 10, the supply port (a) and the load port (b) are made to be placed in a communication condition. Under this condition, when a pressure higher than the supply pressure is applied from the load port (b), the steel ball 10 is pressed to a seat 27 to function as a check valve.
