摘要： A high-pressure cleaning appliance with a high-pressure pump is provided. The pump has at least one pump chamber connected to a suction line and a pressure line. The pressure line is in flow connection with the suction line via a return flow line. A relief valve with a through-channel extending from a valve inlet to a first valve outlet is arranged in the return flow line. A valve element which in a closed position bears against a valve seat is held for movement in the through-channel. At least one outlet channel, which opens into a second valve outlet, branches off from the through-channel. The valve element is surrounded by a sealing ring which seals off an inlet area of the through-channel adjacent to the valve inlet from an outlet area of the through-channel adjacent to the first valve outlet.

摘要： The invention relates to a high-pressure cleaning appliance with a high-pressure pump, comprising at least one pump chamber which is connected to a suction line and a pressure line. The pressure line is in flow connection with the suction line via a return flow line, and a relief valve with a through-channel extending from a valve inlet to a first valve outlet is arranged in the return flow line. A valve element which in a closed position bears against a valve seat is held for movement in the through-channel. At least one outlet channel, which opens into a second valve outlet, branches off from the through-channel. To design the high-pressure cleaning appliance so that it is less susceptible to failure, it is proposed that in the direction away from the valve seat, at a spacing from the at least one outlet channel, the valve element be surrounded by a sealing ring which seals off an inlet area of the through-channel adjacent to the valve inlet from an outlet area of the through-channel adjacent to the first valve outlet.

摘要： A pump for a high-pressure cleaning apparatus for delivering cleaning liquid is provided. The pump has at least one pump chamber into which at least one reciprocally movable piston plunges. The pump chamber is connected via at least one inlet valve to a suction conduit and via at least one outlet valve to a pressure conduit. A bypass conduit leads from the pressure conduit to the suction conduit. A bypass valve is arranged in the bypass conduit. The valve body of the bypass valve is connected to a control member which displaces the valve body to a closed or an open position and displaces a switch plunger which is coupled to the valve body to a first or a second switch position. The valve body opens a passage upstream of the valve seat which becomes wider when the valve body is at a predetermined distance from the valve seat.
