Abstract

A windshield cleaning system with a spraying device is described, in which windshield cleaning system a jet element made of an elastic material is carried in an adjustable jet body formed in the shape of a ball. The jet element is formed with elastic lips forming a spraying mouth which is normally closed and which is located outside of the jet body. The spraying mouth is opened by the pressure of the washing liquid. With such an arrangement the direction of the spraying jet can be adjusted and the washing liquid is prevented from freezing due to the fact that the spraying mouth can be closed.
