Abstract
The invention is a very inexpensive infinite ratio variable transmission which uses a rotatable case type fluid torque pump as the fluid coupled transfer between engine and planetary system. Its rotor is powered by the engine shaft and pumps fluid into a passage through a portion of the casing encompassing and carried by the same power shaft. A fluid system incorporating manual and vacuum controls, restricts the flow of rotor pumped fluid from the casing to cause the casing to rotate, due to retricted fluid flow to power the load and a passage closure secures the engine to the load.
