バルブ。 It has a flow path for communicating the intake port of the auxiliary pump with the atmospheric pressure region, and a valve body that is closed when energized is interposed in this flow path. An auxiliary pump characterized by being equipped with a flow rate control mechanism that operates using the differential pressure between the channel pressure on the pump side and the atmospheric pressure, and gradually increases the channel area as the differential pressure decreases. leak valve.
