ABSTRACT:
A linear hydraulic motor including a first piston rod (12) and piston head (16), a second piston rod (18) and piston head (26), and a cylinder housing (30), having a divider wall (46), adapted to reciprocate longitudinally on the piston heads (16, 26). The cylinder housing (30) has end members (34, 36) through which piston rods (12, 18) extend. Four fluid chambers (52, 54, 56, 58) are formed within the linear hydraulic motor. Fluid chambers (52, 56) communicate with each other through conduits (62), and fluid chambers (54, 58) communicate with each other through conduit (64). Piston rods (12, 18) include conduits (68, 70) for fluid communication with chambers (54, 56). A snubber (74) is provided in the divider wall (46) of the cylinder housing (30). The snubber (74) reciprocates within the divider wall (46) and is adapted to abut the inner ends of the piston rods (12, 18) as the divider wall (46) approaches piston heads (16, 26) during the reciprocating process.
