Claims

[Scope of utility model registration request]

A switching valve chamber and a check valve chamber are provided in a hollow cylindrical valve casing, adjacent to each other in the axial direction of the valve casing, and the switching valve chamber is provided with a liquid feeding path communicating with the injection nozzle at an appropriate position. a first liquid supply path leading to the first washer liquid tank at a position facing the partition wall between the check valve chambers and communicating with the check valve chambers; and a switching liquid supply path communicating between the two valve chambers at the partition wall. are respectively opened, and are housed in the switching valve chamber so as to be reciprocally movable between the openings of the first liquid supply path and the switching liquid supply path,
comprising a switching valve body that switches between opening and closing both openings, and
A second liquid supply passage leading to a second washer liquid tank is communicated with the check valve chamber at an appropriate position, and is accommodated in a reciprocating manner facing the opening of the switching liquid supply passage, so that the second liquid supply passage leads to the second washer liquid tank at an appropriate position. The switching valve element and the check valve element are provided with a permanent magnet having magnetic poles arranged in a direction that attracts each other, and the valve casing is provided with a non-return valve element that opens and closes. The two valve bodies support an excitation coil that operates in directions away from each other, and when the excitation coil is not energized, the two valve bodies pull together to close the switching liquid supply path from both sides of the partition wall, and the excitation coil The vehicle is configured such that the switching valve body is moved from the switching flow path side to the side that closes the first fluid supply path, and the check valve body is moved from the switching flow path side to the side that opens the switching flow path, respectively, by energizing the switching flow path. Washer liquid path switching device.
