Abstract
A coolant pump includes an outlet volute comprising a pivot axis, an impeller pump, a housing, and an outlet valve arrangement. The housing comprises an outlet volute housing defining the outlet volute and comprises a volute housing wall comprising a recess, and a first outlet channel comprising a valve opening. The outlet valve arrangement is disposed in the first outlet channel and comprises a valve body which opens or closes the valve opening. The valve body comprises a circle segment body comprising a proximal surface and a maximum outside radius. The circle segment body is rotated around the pivot axis. The proximal surface is distant from the pivot axis by an offset distance which is at least ¼ of the maximum outside radius. The recess houses the circle segment body in the closed valve position. A lateral distance of the pivot axis to the volute housing wall is approximately equal to the offset distance.
