ABSTRACT:
A drive apparatus for a rotary output member of a vehicle or the like includes a pair of orbiting members having outwardly-projecting teeth which engage with inwardly-projecting teeth of an output member. Hydraulically-actuated piston and cylinder means provide orbiting of the orbiting members, through a rotary valving element, to in turn rotate the rotary output member.
