ABSTRACT:
A hydraulic motor system mechanism for driving a member selectively in opposite directions and to either of a pair of positions in either direction. The mechanism comprises two pairs of double acting hydraulic cylinders with interconnecting piston rods, whereby selective pressurization of a cylinder of either pair of said cylinders effects movement of the member in one direction to a first position and pressurization of the other cylinder of the pair effects movement to a second and further position in the same direction. Pressurization of one or both cylinders of the other pair effects movement of the member to a first or second and further position in an opposite direction.
