摘要： A mechanical coolant pump for an internal combustion engine includes a pump housing defining an outlet volute, a first outlet channel comprising a first valve opening, a second outlet channel comprising a second valve opening, an impeller pump wheel, and an outlet valve arrangement. The second outlet channel is separate from and fluidically parallel to the first outlet channel. The impeller pump wheel pumps a liquid into the outlet volute. The outlet valve arrangement is fluidically upstream of the first outlet channel and the second outlet channel. The outlet valve arrangement comprises an integral valve body which pivots between an open position and a closed position. The valve body comprises a first retaining section and a second retaining section. When the valve body is in the closed position, the first retaining section completely closes the first valve opening and the second retaining section only partially closes the second valve opening.
