摘要： A drive device for a high pressure cleaning appliance includes a motor, the motor shaft of which is rotatably mounted on a motor flange and is coupled to a swash plate arrangement by a planetary gearing, wherein the planetary gearing comprises a sun gear, which is connected to the motor shaft in a rotationally-fixed manner and meshes with planetary gears that are rotatably mounted on a planet carrier and are in engagement with an internally toothed ring gear, and wherein the swash plate arrangement is positioned in an oil housing. So that the drive device has a longer service life and enables a greater selection of materials in the production thereof, the motor flange and the oil housing form separate components, wherein the motor flange comprises the ring gear and the oil housing is fixed to the motor flange, wherein the motor flange forms a centering for the oil housing.

摘要： A manually operated pressure fluid device has a housing structure which receives a motor-pump group and has a fluid inlet connected to the pump on the intake side and a fluid outlet formed on a nozzle unit and connected to the pump on the delivery side, an electrical power source and a control element acting on the power supply of the motor. The motor of the motor-pump group is a brushless DC motor and the pump is a whirling rotor pump having two lock washers, each having an annular face spline, where the number of teeth of the two face splines intermeshing with each other differ from each other by one and the lock washers arranged at an angle relative to each other wander relative to each other such that the face splines delimit a plurality of pump chambers which increase and reduce in size during pump operation.

摘要： The steps of providing a cleaning device, a liquid proportioning device and a series of tanks filled with liquids. The cleaning device has a nozzle, a series of hoses and a pump. The liquid proportioning device includes a series of passageways, having three chambers and two valves, and a manifold for mixing the liquids to form a cleaning solution. The passageways include knobs to set the ratio of each liquid that the user desires to mix into a cleaning solution. Once the cleaning solution is mixed, it is fed through a pump to cleaning device for use. The proportioning device allows a user to easily, quickly and accurately mix liquids to form a cleaning solution.

摘要： Disclosed is a method and apparatus for performing high volume washing, namely, using drones to perform cleaning services. A drone is navigated about a cleaning path; the cleaning path being either pre-defined or delineated in real-time. A cleaning solution is pumped to a solution distribution mechanism of the drone, wherein the cleaning solution is directed onto the surface to be cleaned. The solution is stored in a supply tank that may be integrated into the body of the drone or outfitted as a standalone structure. A temperature regulator is integrated with the supply tank in order to control a wash temperature of the cleaning solution. The solution distribution mechanism may be rotatable about 360 degrees. A camera array observes a spray area of the solution distribution mechanism, wherein a live feed is transmitted to a monitoring unit.

摘要： A high-pressure washing machine is provided, which can stop a brushless motor even if the function of a microcomputer declines. The high-pressure washing machine is provided as a high-pressure washing machine 10 having a pump 12 which sucks and discharges a washing solution and a brushless motor 14 supplied with current to drive the pump 12. The high-pressure washing machine 10 includes an inverter circuit 29 which when the pump 12 driven by power from the brushless motor 14 discharges the washing solution, controls the rotation speed of the brushless motor 14, a driver circuit 30, a microcomputer 31, and a motor operation stopping circuit 37 which detects the discharge pressure of the pump 12 and which based on the result of the detection, switches on and off an electric circuit E1, which supplies current to the brushless motor 14.
