Patent ID: 6915731

Claim:
A cylinder-piston drive, comprising: an operating piston adapted to be displaced inside a cylinder and to delimit pressure chambers by piston sides facing away from one another, the operating piston including a multipart design and including at least two partial pistons inserted inside one another, the partial pistons displaceable relative to each other and adapted to strike against one another at stop faces, one pressure chamber delimited by all of the partial pistons and another pressure chamber delimited by less than all of the partial pistons, at least one reduced sliding path of the partial pistons not delimiting the other pressure chamber less than an overall sliding path of the operating piston; and at least one stop face arranged on the cylinder adapted to strike against a further stop face of one of the partial pistons after the one of the partial pistons travels one reduced sliding path; wherein at least some of the stop faces associated with each other include conical surfaces that form a conical seat when striking against one another.
