Abstract: 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.
