Title:
VALVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163533
Kind Code:
A1
Abstract:
Provided is a valve device capable of properly performing switching between a valve-opened state and a valve-closed state. For the valve-closed state, a partitioning wall through-hole 131 is brought into a closed state by a solenoid part 160, and a total forward load, which acts on a valve 140 by a spring and the pressure of oil in a hydraulic control space R1a, is caused to be greater than a rearward load, which acts on the valve 140 by the pressure of oil flowing in through an inflow hole 121, so that the valve 140 is moved forward so as to allow an outflow hole 112 to be closed. For the valve-opened state, the partitioning wall through-hole 131 is brought into an opened state by the solenoid part 160, and the rearward load, which acts on the valve by the pressure of oil flowing in through the inflow hole 121, is caused to be greater than the total forward load, which acts on the valve 140 by the spring and the pressure of oil in the hydraulic control space R1a, so that the valve 140 is moved rearward so as to allow the outflow hole 112 to be opened. Four front-wall inflow holes 144 are provided.
