Abstract
A pump used to selectively force-feed under pressure washer fluid to the front and rear windscreens of a vehicle according to the rotation of an impeller in either one or other direction. A bypass flow passage for taking out part of the washer fluid, which is forcibly fed under pressure by means of the impeller, is formed upon supply of the washer fluid to the rear windscreen. Thus, the washer fluid delivered to the front windscreen and that delivered to the rear windscreen are different in the delivery rate.
