When a second hydraulic chamber has higher hydraulic pressure than a first hydraulic chamber, a hydraulic pressure difference between the first and second hydraulic chambers acts on the valve seat to separate the valve seat from the valve member against the biasing force of the biasing member so that the first hydraulic chamber and the second hydraulic chamber come into fluidal communication.Type: ApplicationFiled: September 30, 2015Publication date: April 7, 2016Inventor: Koji ITO
