PURPOSE:To prevent a motor output from shortage and get a good wash in spite of increase of nozzles by constituting the 1st and the 2nd outlet of a solenoid valve so that they may by opened alternately every given period. CONSTITUTION:If the switch 15 for a head lamp washer is turned on when an ignition switch 14 is on, the coil 13a of a relay 13 is magnetized and contacts A, B turn on. Thereby, the instant a pump motor 3 begins to rotate, a control unit 12 comes in motion and controls a solenoid valve 5 at a given period. When the solenoid valve is close, outlets 5b, 5c are respectively opened and closed and when the valve is open, the outlets are respectively closed and opened. Accordingly, washing water is jetted alternately to the 1st nozzles 10, 11 and the 2nd nozzles 10a, 11a. In the result the right and left head lamps HL are washed by strong cleaning force in the wide range. |
