摘要： The invention relates to a high-pressure cleaning device with a motor pump unit, comprising a pump head on which a piston assembly is placed. Said piston assembly, with the intermediate of a planetary gear, carries a drive motor and comprises a plurality of pistons that can be reciprocated in the longitudinal direction of the motor pump unit. Said pistons dip individually into a pump chamber of the pump head and a swash plate unit interacts with the pistons. The planetary gear has a sun gear which is connected to the motor shaft of the drive motor in a rotationally fixed manner and is coupled to a hollow gear via planet wheels that are rotationally received by a planet carrier. The planet carrier is connected to the swash plate unit in a rotationally fixed manner. The aim of the invention is to provide a high-pressure cleaning device in which the planetary gear is easy to lubricate even with the motor pump unit being arranged in a substantially vertical position. For this purpose, the piston aggregate is provided with an oil sump into which an oil-transfer pipe that is coaxial to the motor pump dips and which is connected to the planet carrier in a rotationally fixed manner, whereby oil from the oil sump can be fed to the planet gear via the oil-transfer pipe.

摘要： A motor pump unit for a high-pressure cleaning unit with the motor (2) and the pump (3) placed in line with one another inside a common housing (1). The housing (1) is designed with a double wall (10, 11) extending, at least, along the longitudinal section of the housing in which the pump (2) and the motor (3) are placed. The hollow space (12) in the double wall (10,11) delimits a flow channel for the relatively cold pressure liquid supplied from the pump. In the hollow space in the double wall there is moreover placed a helical coil (15). By means of the double wall, efficient cooling of the motor pump unit is obtained without the use of flow channels incorporated in cast motor housings.

摘要： The invention relates to a drive device (10) for a high-pressure cleaning unit having a motor (12), the motor shaft (14) of which is coupled to a swash plate (18) via a planetary gear set (16), wherein the planetary gear set has a sun gear (26) connected in a rotationally fixed manner to the motor shaft, which sun gear meshes with planetary gears (28, 29) which are mounted so as to be able to rotate on a planetary bearing (35) and engage with an internally toothed internal gear (31) and with their end side facing away from the planetary bearing lie against a support element (60) so as to able to slide. In order to construct the drive device in such a manner that it has an increased service life, it is proposed according to the invention that the support element takes up a wear-inhibiting bearing region for the planetary gears. Alternatively, or supplementary thereto, it is proposed that the swash plate is supported by a bearing plate (40) which dips into a receptacle (42, 74) which supports the bearing plate in an axial and radial direction.
