Abstract: A nozzle system for cleaning a vehicle part of a motor vehicle includes a nozzle body having a nozzle for applying a cleaning liquid to the vehicle part. A fluid line arrangement is configured for connection to a fluid-based cleaning system of the motor vehicle in order to conduct the cleaning liquid to the nozzle body. An electrically conducting heating wire runs through the fluid line arrangement and through the nozzle body. The heating wire has a first portion with a first cross section and a second portion with a second cross section where the first cross section is larger than the second cross section.

Abstract: A cleaning unit for a window or a sensor in a motor vehicle includes a reservoir for a cleaning liquid, at least one cleaning nozzle provided in or on a cleaning nozzle unit, a fluid connection between the reservoir and the cleaning nozzle and at least one spray pump provided between the reservoir and the cleaning nozzle. The spray pump is formed by a piston-cylinder unit that has a cylinder axis and is provided in or on the cleaning nozzle unit. The cleaning unit is characterized in that the piston of the piston-cylinder unit is designed as an electromagnetically actuated piston, which can be actuated in a first direction under the action of an electromagnetic force directed along the cylinder axis, which first direction forms a compression direction.
