用ウオツシヤポンプ。[Claims for Utility Model Registration] (1) A washer pump for a vehicle in which cleaning fluid discharged from a pump chamber is selectively supplied from a first outlet or a second outlet via a valve chamber, The flow path to the first outlet is provided with a bypass passage that bypasses a part of the cleaning liquid flowing through this flow path, and the cleaning liquid is discharged from the first outlet and the second outlet at different pressures. Features of vehicle wash pump. (2) In claim (1), the valve chamber is: a first valve chamber provided between the pump chamber and the first outlet; and a first valve chamber provided between the pump chamber and the second outlet. a second valve chamber, and the first valve chamber is provided with a bypass flow path that bypasses a part of the cleaning fluid flowing toward the first outlet toward the cleaning fluid intake port. Washer pump. (3) In claim (1), the valve chamber has two valve seats communicating with the first and second outlets, and the valve is opened by pressure generated by the rotational direction of the impeller in the pump chamber. The bypass flow path is configured to selectively block the two valve seats, and the bypass channel directs a portion of the cleaning fluid flowing toward the first outlet only when the valve closes the valve seat of the second outlet. A vehicle wash pump, characterized in that it is configured to bypass the water.
