  • Patent number: 5429306
    Abstract: In order, on the one hand, to be able to use a high-pressure cleaning device comprising a high-pressure pump, a liquid supply and a pressure line for the liquid supplied by the pump as well as a housing surrounding the pump, in the usual way as a portable device and on the other hand, however, to facilitate transport without increasing the overall dimensions, it is proposed that rollers be arranged on the underside of the housing in the area of a side edge and that a handle insertable into the housing be mounted therein, the handle being shiftable between an inserted position in the housing and an extended position and securable in both these positions.

  • Patent number: 5328097
    Abstract: In order to reduce the undesired rotation of the nozzle body about its own longitudinal axis in a rotor nozzle for a high-pressure cleaning device comprising a casing having in a front wall a pot-shaped recess with a central opening therein, a nozzle body with a bore extending through it, the nozzle body being supported at a spherical end in the pot-shaped recess, extending in the longitudinal direction over part of the casing and having an outside diameter which is smaller than the inside diameter of the casing, and an inlet for a liquid opening tangentially into the casing and causing the liquid to rotate about the longitudinal axis in the casing so that the nozzle body rotates together with the rotating liquid and when doing so bears with a bearing surface at its circumference on the inside wall of the casing with the longitudinal axis of the nozzle body at an incline to the longitudinal axis of the casing, it is proposed that the bearing surface of the nozzle body consist of a material with a coefficient
