Abstract
A vehicular windshield washer system in combination with a windshield wiper having a wiper arm. The washer system is comprised of a pair of washer nozzles mountd on the wiper arm and so directed to eject washer fluid to opposite sides of the wiper arm upon being supplied with washer fluid. The washer fluid from a washer fluid source is selectively supplied to the washer nozzles in accordance with movement of the wiper arm. The washer fluid is suppliable to one of the washer nozzles upon rotational movement of the wiper arm in one direction and to the other washer nozzle upon rotational movement of the wiper arm in the other direction. The rotational movements turn at a turning position of the wiper arm. Additionally, the washer fluid is supplied to the one washer nozzle until the wiper arm reaches a position slightly forward of the turning position and stopped to be supplied to the same washer nozzle for a duration of rotational movement of the wiper arm from the slightly forward position to the turning position, thereby saving washer fluid and preventing washer fluid from scattering sideward of a vehicle body.
