Abstract: A wash system for window glasses and/or headlamps of a vehicle, with a fluid line through which a fluid is conducted from a fluid reservoir into a nozzle and with a heating cable which is laid in the fluid line is disclosed. The heating cable is laid so as to enter the nozzle or to pass through the nozzle and to heat not only the fluid line but also the nozzle. One obtains a wash system that can be manufactured at low cost and ensures freeze protection at reduced energy expense by the fact that the heating cable is laid in a meander pattern in the nozzle.

Abstract: A fluid supply hose for a windscreen or headlamp washer system of a vehicle having an electric heating element, said heating element comprising a coaxial cable (2, 12) with an inner current conductor (3, 13) and an outer current conductor (5, 15) surrounding said inner conductor (3, 13), an insulator (4, 14) being provided between said inner (3, 13) and said outer conductor (5, 15). To provide a fluid supply hose of the type mentioned herein above the heating element of which is of a small and flow-enhancing design so that the fluid supply hose may have a smaller cross section, the inner current conductor (3, 13) is given a higher electric resistance than the outer current conductor (5, 15).

Abstract: In a washer system (9) which is intended for a motor vehicle, a delivery unit (1) is used to supply a washer nozzle (11) which is connected by means of a pipe element (10). To protect against damage at low ambient temperatures, a heating element (5) is arranged on a housing (7) of a pump chamber (3) of the delivery unit (1) and thus makes it possible for the washer fluid situated in the pump chamber (3) to be heated rapidly and in a specific manner.
