Title:
SOLENOID VALVE
Document Type and Number:
WIPO Patent Application WO/2013/105411
Kind Code:
A1
Abstract:
Provided is a solenoid valve with which it is possible to prevent noise generated due to repetitive collisions between the valve seat and the valve body that occur when the degree of opening of the passage is small, and with which the degree of opening of the passage is stable. This solenoid valve, with which the volume or pressure of an operating fluid can be changed by changing the degree of opening of the passage between the valve seat and the valve body by means of a PWM-controlled solenoid, is characterized in that a friction member, which makes contact with the outer circumference of a reciprocating member directly driven by the driving of the solenoid, is provided on a stationary-side member at the periphery of the driven reciprocating member.
