Zusammenfassung:	A continuously variable friction drive transmission has expandable fluid housing members on both the input shaft and the output shaft. The housing members are in fluid communication with a control valve which is operable to establish the fluid pressures in the housings. The housings are maintained in frictional engagement by the internal fluid pressure such that power can be transmitted between the shafts. The drive ratio between the shafts is determined by the internal pressures of the housings which establish the outer diameters thereof. The drive ratio is changed by changing one or both of the internal fluid pressures.
