Abstract

A nozzle carrier for a windshield washing apparatus has an outer cylinder (1) and a telescoping inner cylinder (2) in the outer cylinder. The inner cylinder has at an end portion thereof a jet nozzle (3) which can be shoved out of the outer cylinder. A first plunger (4) is sealed about its periphery to the outer cylinder and is movable by pressure of washing liquid away from a second plunger (5). In this manner the inner cylinder is shoved out of the outer cylinder. When both cylinders are at their greatest spacing from one another they determine, together with the outer cylinder, a space which serves to receive a particular quantity of washing liquid. Thereafter, the second plunger is urged, by pressure of the washing liquid, toward the first plunger. This causes, after the opening of a valve in series with the jet nozzle, the washing liquid to flow through a passageway (8) of the first plunger toward the jet nozzle.
