Abstract
A torque converter comprises a stationary housing within which a rotatable impeller is mounted for driving a rotatable trubine. The bladed impeller is mounted on an engine driven input shaft, and the bladed turbine is mounted on an output shaft on the same axis as the input shaft. The impeller blades and turbine blades move through an annular oil-filled passage. A plurality of stator blades are disposed in the passage in spaced-apart radial arrangement around the axis of the shafts. Each stator blade is divided into two sections, namely, a fixed forward section and an adjustably movable or pivotable rear section. Means are provided to pivot the rear sections of all of the stator blades simultaneously so as to vary the width of the flow channel between each pair of adjacent stator blades between fully opened and fully closed positions and any position therebetween to thereby control the amount of oil available for use by the impeller and turbine and thereby enable regulation of the power output of the torque converter. The movable rear section of each stator blade is provided with a stem which extends through a sealed opening in the stationary housing and enables pivotal adjustment …
