Abstract
A piston-cylinder assembly for displacing a load through a long stroke consists of a rod, a piston slidable on the rod and by fluid pressure the piston is clamped to the rod, and a cylinder in which the piston is contained. By clamping the piston to the rod and introducing fluid into the cylinder, relative movement is caused between the piston and cylinder and the rod. When one assembly is used, the movement is intermittent but, by mounting two pistons on the rod, each piston being in a separate cylinder, and by controlling the flow of fluid, the movement is continuous.
