Abstract
A hydraulic fluid plenum plate assembly in a torque-coupling assembly, non-rotatably mounted to a rotatable coupling case thereof so as to form a plenum chamber between the plenum plate assembly and the coupling case. The coupling case has an inlet port fluidly connecting the plenum chamber with a hydraulic pump disposed within the coupling case. The plenum plate assembly comprises a pickup tube for supplying a hydraulic fluid from a fluid reservoir to the plenum chamber. The pickup tube has inlet and outlet ends. The inlet end has an inlet opening submerged in the hydraulic fluid in the fluid reservoir. The outlet end has an outlet opening fluidly connecting the pickup tube with the plenum chamber. The outlet opening is disposed above the inlet port in the coupling case at any angular position of the coupling case relative to the plenum plate assembly.
