摘要 |
A device for delivering washing liquid to two spraying nozzles spaced from each other at two areas of a pane being washed or two panes being washed comprises a pump with a rotor driven in two opposite directions and a delivery unit connected to the pump and having two pressure chambers with two outlets connected to the respective nozzles and each alternatively receiving the liquid from the pump. A limiter which separates the chambers from each other has two portions movable under pressure and each provided with a sealing diaphragm which closes the respective outlet. Two diaphragms can close both outlets when the pump is in non-operative position.
