ABSTRACT:
Total apparatus includes extensible and retractable means for moving a load linearly between two or more spaced positions, the load having a fluid pressure operated motor, and means for delivering fluid from a pressure source to the motor at selected stages of extension. A cylinder having a head end and a shaft bearing end houses a piston rod and piston which are reciprocated by fluid pressure through a pair of actuation ports. A passage extends through the length of the piston rod and through the piston to a marginal wall. Fluid pressure power ports extending through the cylinder wall are spaced longitudinally at selected stations and the piston may be moved to any station, where its passage registers with the corresponding power port. Fluid from the pressure source may then be delivered through the piston and rod and by conduit means from the outer end of the rod to the motor on the load. There are no swivel joints or hoses in the fluid path to leak or deteriorate in use.
