ABSTRACT:
In a high-pressure cleaning apparatus comprising an electric motor arranged in a housing, a high-pressure pump arranged in a housing with at least one piston entering a pump chamber in a sealed manner, and a swash plate carried by a motor shaft protruding from the housing of the electric motor, with the piston or pistons of the high-pressure pump resting in a resilient manner against the swash plate, in order to achieve electrical insulation in the region of the swash plate drive, it is proposed that the transition from the motor shaft via the swash plate to the piston or pistons be electrically interrupted by an electrically insulating material being interposed therebetween.
