Abstract
A filter element is accommodated in a filter case. A housing is affixed to the filter case. A partition plate is located between the filter case and the housing. A switching valve is equipped in the housing. The switching valve includes a solenoid actuator, a valve, and a valve seat member. A vibration transmission member is located on one side in a driving direction of the valve relative to the valve seat member. The vibration transmission member is in contact with the switching valve at one end and is in contact with the partition plate at the other end. The vibration transmission member transmits oscillation, which is caused when the valve is seated on the valve seat, to the filter element through the partition plate.
