Abstract

The piston (4) inside the cylinder reciprocates and connects to the piston rod (41) which feeds axially from the cylinder head (2) or from the cylinder floor (3). To facilitate supply and exhaust of the compressed air into or out of the cylinder (1) there is both an inlet and an outlet. The slide valve gear (8) is fixed to a piston which moves within a control cylinder. The cylinder contains control openings which provide a supply and exhaust connection for compressed air control of the piston.
