The invention refers to hydraulic rotation transmission with two side output of driving shaft and one side output of driven shaft and can be used in power transmissions and transmissions where the stepless ratio variation is essential. It also can be used as stepless speed variation device in bicycles (Fig. 1). Getting any transmission ratio at reduced dimensions and mass is achieved in the hydraulic transmission by applying new scheme, including motionless and movable bodies containing two coupled rotors, composing of camshafts with pistons and separated by motionless wall. Transmission ratio varies from 0 to maximal value displacing the movable body in axial direction by means of overhanging control arm.
