Abstract (en)

[origin: EP2299120A1] The invention refers to a switchable mechanical coolant pump (10) for cooling an internal combustion engine (12). The coolant pump (10) is provided with a rotatable drive wheel (24) driven by the engine (12), a pump wheel (30) being directly connected with the drive wheel (24), the pump wheel (30) comprising a wheel disk (34) and pump blades (32) projecting axially from the wheel disk (34), a separate control disk (40) being axially movable and being provided with blade slits (44), the control disk (40) being provided at the pump wheel (30) so that the pump blades (32) are received in the blade slits (44), so that the blade height of the pump blades (32) between the wheel disk (34) and the control disk (40) is axially adjustable by axially shifting the control disk (40), and an actuation element (46; 70) for actuating the control disk (40).
