Abstract
A controllable coolant pump, insertable in a coolant circuit of an internal combustion engine includes a pump housing, in which a hollow pump shaft is supported rotationally with an allocated impeller. Rotation of the impeller conveys coolant. To control a volume conveyed by the coolant pump an axially displaceable guide disk is provided, allocated to the impeller and cooperating with an actuating mechanism. The guide disk is connected to a push rod, guided in the pump shaft, and is displaceable between two end positions defined by a rear wall and a pump cover of the impeller. The actuating mechanism further includes a displacement pump integrated in the coolant pump, with a coolant flow of the displacement pump being supplied for adjustment of the guide disk via a control valve to an actuator, which includes a piston in a pressure chamber in the pump shaft connected to the push rod.
