ABSTRACT:
A drive assembly has a plurality of piston/cylinder drive units each of which has a piston component longitudinally fixed to a fixed transverse frame member. First and second working chambers in a movable cylinder component are connected to pressure and return through passageways extending through the piston rod of the piston component. A ball member on the outer end of the piston rod is received in a socket structure that has passageways communicating with the piston passageways. A manifold structure is secured to the socket structures and houses a plurality of internal valves including a switching valve with a single external pressure port and a single external return port. The socket structures and manifold structure have abutting surfaces that form internal fluid connections to allow operation of the conveyor without external fluid ports other than the two ports of the switching valve.
