Abstract:
1. A nozzle body for a cleaning system on a motor vehicle, comprising: at least one feed line element adapted for connection to a cleaning liquid supply container; a basic body having a channel section; at least one return-flow line element adapted to be connected to the cleaning liquid supply container, wherein the connecting channel section includes a bybass element between the feed line element and the return-flow element, and wherein the bybass element comprises a tap line section which penetrates the basic body from the outside through a wall and penetrates the connecting channel section between the feed line element and the return-flow element, forming an intersection, wherein the tap line section is closed off by a closing element at the location where the tap line section penetrates the wall of the basic body; at least one nozzle element connected to the feed line element by the channel section in the basic body; and a heating device to heat the connecting channel section and arranged adjacent to the nozzle element, such that the nozzle element is located in a heating zone that is primarily heated by the heating device, wherein the heating device comprises an electrical resistance heater including two ring-shaped, substantially aligned electrical terminal contact elements defining substantially parallel ring planes, between which the heating zone is located, and wherein the nozzle element is located in the heating zone through which a heating current flows between the terminal contact elements and the heating zone comprises a portion of a volume of the basic body made of conductive plastic.
