Abstract
An axial, through-shaft actuator that is particularly useful for a variably actuatable water pump having a pump chamber, with an inlet and an outlet is provided. A hollow drive shaft extends into the pump chamber. A drive wheel is connected to the drive shaft. A variable flow impeller assembly having an impeller part connected to the drive shaft and a cover part, which is axially movable relative to the impeller part is located in the pump chamber and is movable from a first, pumping position to a second position to prevent pumping. A cup actuator assembly is axially movable on the hollow drive shaft, and includes an actuator plate and a pin extending through the hollow drive shaft that connects the axially movable impeller part and the actuator plate. An actuator displaces the actuator plate in the axial direction of the drive shaft to move the axially movable part.
