Abstract

A nozzle element is described, which can is inserted into a nozzle body, either fixed in position or adjustably, and together with the nozzle body forms a component of a windshield wiper system of a motor vehicle. The nozzle element consists of a hard metallic, ball-like base body and a cylindrical projection formed in one piece with the body. A hose-like resilient sleeve is pulled tightly onto the body, and closes off the outer ends of transverse channels which are in flow connection with a centered flow channel. Via the channel, washing fluid for the windshield is supplied under pressure. Thereby, the resilient sleeve bulges outwards so that the fluid can flow out of the nozzle element on the inside of the sleeve and on the outside of the cylindrical projection via an annular channel formed under pressure.
