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.
