  • Variable drive apparatus
    Patent number: 4981201
    Abstract: An infinitely variable high efficiency drive mechanism that can act as a transmission or as a coupling between a prime mover and the reducing gears of a standard or automatic transmission, replacing a clutch or torque converter as a means of power transmission. This mechanism includes a hydraulic pump with a self-contained valve that keeps high pressure oil flow to a minimal distance. It can regulate shaft output torque ratio from zero (neutral) to 1:1 in locked position with minimal efficiency losses.
