Abstract
A coolant pump includes a drive wheel, a driven wheel, and a coupling-control pump. The driven wheel is connected to a coolant impeller and coupled by a variable degree to the drive wheel, the degree of coupling responsive to an amount of fluid confined between the drive wheel and the driven wheel. The coupling-control pump is configured to change the amount of fluid confined between the drive wheel and the driven wheel based on a variable control signal.
