摘要： A piston pump for a high-pressure cleaning appliance is provided, including a pump block having a plurality of pump chambers, into each of which one piston plunges, and including a pump head having a suction inlet and a pressure outlet, each pump chamber in flow connection via a suction valve with the suction inlet and via a pressure valve with the pressure outlet, and including a clamping bracket engaging around the pump head. The piston pump can have a single U-shaped clamping bracket oriented symmetrically in relation to the longitudinal pump axis, and the pump head and the pump block form between them downstream of the pressure valves a pressure chamber in which a central, piston-like insert part is arranged, the insert part being surrounded by a sealing element and having a passage, and a pressure line oriented coaxially with the longitudinal pump axis being arranged downstream of the passage.

摘要： A motor-pump unit includes an electric motor and a pump. The electric motor has a motor housing, on the outside of which a cooling channel is arranged. The pump has a suction inlet and a pressure outlet. Liquid to be pressurized can be fed by way of the cooling channel to the suction inlet. In order that the motor-pump unit can be produced and assembled more cost-effectively, the motor housing includes a first housing part and a second housing part, which are connectable to each other in a liquid-tight manner and between them form the cooling channel.

摘要： A piston pump for a high-pressure cleaning appliance is provided, including a plurality of pump chambers, into each of which one piston which is movable back and forth plunges, and which are each in flow connection via a suction valve with a suction inlet and via a pressure valve with a pressure outlet, the suction valve including a suction valve closing member which is sealingly positionable on a suction valve seat, and the pressure valve including a pressure valve closing member which is sealingly positionable on a pressure valve seat, the pressure valve seat and the suction valve seat being at different radial distances from a longitudinal pump axis. To increase piston pump mechanical stability without increasing material thickness, the pressure valve seat can be arranged, in relation to the longitudinal pump axis, offset from the suction valve seat in the circumferential direction of the piston pump.

摘要： A piston pump for a high-pressure cleaning appliance is provided, including a plurality of pump chambers into each of which one piston which is movable back and forth plunges, and which are each in flow connection via a suction valve with a suction inlet and via a pressure valve with a pressure outlet, the pistons each being surrounded by a sealing ring which is supported in the radial direction by a ring wall and in the axial direction by a support ring. In order to develop the piston pump in such a way that it can be manufactured and assembled more cost-effectively, it is proposed that the piston pump includes a one-piece support shield which forms the support rings and surrounds the ring walls in the circumferential direction.
