摘要： A cleaning apparatus, optimized for cleaning optical and optoelectronic sensor devices in motor vehicles, comprising a housing, and a reciprocating piston movable in a pressure-controlled manner in the housing and movable from a retracted position into a deployed position along an actuation axis is disclosed. The reciprocating piston has an inner channel to transport a cleaning fluid through the reciprocating piston to a spray nozzle. A miniaturized, easily and inexpensively producible cleaning apparatus which makes possible exact and precise orientation of the cleaning jet, quick operational readiness, reduced tendency for follow-up flow of the cleaning fluid, and improved adaptability to different installation positions, is also disclosed. In an embodiment at least the cleaning apparatus has at least one guide to prevent rotation of the reciprocating piston about the actuation axis during its entire stroke, the at least one guide means arranged at least regionally in the inner channel.

摘要： Disclosed is a cleaning device for a washing apparatus arranged in a vehicle, comprising a housing with a chamber which is formed in the housing, is configured to be filled with cleaning fluid and is hydraulically connectable to at least one spray nozzle for the cleaning fluid, and with at least one heatable heating wire protruding at least in sections into the chamber. To obtain high functional reliability even at low temperatures and to permit particularly rapid and reliable deicing, a heat-conducting element is arranged in the chamber to enlarge a heat-transferring convection surface, said heat-conducting element absorbing the heat from the heating wire, and being at least partially, and preferably completely, surrounded by the cleaning fluid.
