The adjustable stroke piston and cylinder includes a piston fixed to one end of a piston rod that extends from one end of the cylinder. An auxiliary piston is sealed with the cylinder and the piston ord and is slidable on the piston rod. The piston rod is tubular with pressure supply ports connecting its bore to a point intermediate the piston and auxiliary piston. A liquid supply connects to the one end of the cylinder to supply pressure liquid intermediate the closed end of the cylinder means and the auxiliary piston to move it axially on the piston rod. This controls the effective length of the piston stroke in the cylinder.
