とにより閉じられている。 One embodiment of the present invention has the above-mentioned configuration, and if the movable contact 12 of the front watch switch 10 as the first switching means is switched to the fixed contact 14 side, the motor 3 is energized. As a result, the rotor 1 is rotated in the normal rotation direction (counterclockwise when viewed from the motor 3 side). Since spiral blades 4 are attached to the outer periphery of the rotor 1, the washer fluid is brought into negative pressure through the first fluid supply channel 5 connected to the tank in which the washer fluid is stored. is sucked into the case 2. Then, the washer fluid is sent along the spiral groove 4A formed on the outer periphery of the rotor 1 in the direction of the second liquid passage 6 that leads to the windshield. A check valve 8 housed within the valve seat 6A is opened by hydraulic pressure, and washer fluid is supplied to the windshield. At this time, the other check valve 9 housed in the valve seat 7A provided near the inlet of the third liquid passage 7 is closed due to the negative pressure in the vicinity of the valve seat 7A in the case 2. .

はリアガラスに供給される。 On the contrary, the movable contact 13 of the rear watch switch 11 as the second switch means is connected to the fixed contact 16.
When switched to the side, the motor 3 is energized and the rotor 1 is rotated in reverse. When rotor 1 is reversed, case 2
Since the pressure inside becomes negative, the washer liquid is sucked into the case 2 from the first liquid passage 5 for liquid supply, and the washer liquid is sucked into the case 2 through the spiral groove 4.
A is sent to the third liquid passage 7 side which communicates with the rear glass. Therefore, the check valve 9 housed in the valve seat 7A provided in the third liquid passage 7 is opened, and the other check valve 8A is opened due to negative pressure in the vicinity of the valve seat 6A in the case 2. It is closed and the washer fluid is supplied to the rear window.

る。 What is shown in FIG. 4 is a second embodiment of the present invention. In this embodiment, the first liquid passage 5 for supplying liquid is formed in bifurcated branch pipes 5A, 5B, and Valve seat 5 provided inside the outlet of the pipes 5A, 5B
Washer liquid stored in the tank by installing check valves 15 and 16 in A 1 and 5B 1 , respectively, is transferred from the first liquid passage 5 to the bifurcated branch pipe 5A,
The check valve 16 attached to the valve seat 5B1 of one of the branch pipes 5B of the branch pipes 5B is opened when the rotor 4 is rotated and the inside of the case 1 becomes negative pressure.
It is sucked into case 1. This embodiment differs from the previous embodiment in that the washer liquid is efficiently sent to the discharge side with a sufficient degree of pressurization while being pressurized along the spiral groove 4A on the outer periphery of the rotor 4. Then, the washer liquid is passed through the check valve 8 mounted on the valve seat 6A in the second liquid passage 6.
When opened, it is supplied to the front side.
On the other hand, when the rotor 1 is rotated in the opposite direction due to the rotation and drive of the motor 3, the check valve 15 is opened and the washer fluid sucked into the case 2 from the branch pipe 5A is transferred to the rotor 1. The check valve 9 is sent to the third liquid passage 7 side by the spiral groove 4A provided on the outer periphery of the check valve 9 and is mounted on the valve seat 7A in the third liquid passage 7.
is opened and washer fluid is supplied to the rear side.
In this case, the check valve 8 is closed by suction because the inside of the case 2 near the valve seat 6A is under negative pressure.

ストが低廉である。 As described above, this device can supply liquid by turning on the first or second switch to rotate the rotor of one pump forward or backward, opening the second or third liquid passage on the discharge side. In addition, the device has a simple structure in which a rotor driven by a motor is housed in a case, and several liquid passages are provided with check valves inside. Since it does not require solenoid valves or piping for switching water passages as in the past, it is easy to manufacture and assemble and costs are low.
