Abstract: An apparatus includes a hydraulic power steering motor. A continuously variable transmission has an input shaft rotatable under the influence of force transmitted from the engine and an output shaft operable to drive a pump. The continuously variable transmission is operable to drive the pump at a first speed when one of the input and output shafts of the continuously variable transmission rotates at a first speed. The continuously variable transmission is operable to drive the pump at a second speed when the one of the input and output shafts rotates at a second speed. A centrifugal sensor is connected with the one of the input and output shafts. The centrifugal sensor transfers rotational movement of the one of the input and output shafts to a linearly displaceable input member of the continuously variable transmission to change the speed at which the pump is driven.
