ABSTRACT:
The fluid conduit of an hydraulic stepless variable transmission has a radial extension at its distal end terminating in a stationary chamber through which fluid is supplied to and discharged from a rotary piston-and-cylinder unit controlling the transmission.
The radial extension rotates within the chamber along with the piston-and-cylinder unit, and thereby acts to compensate for pressure build-up within the cylinder chamber resulting from the effect of centrifugal forces.
