ABSTRACT:
A hydraulic adjustment apparatus as is for instance used to adjust a roller of a rolling mill has a cylinder forming a first cylinder chamber and having a first cylinder surface directed backwardly in a predetermined direction in the first chamber. A first piston is displaceable forwardly and backwardly in the direction in the first chamber relative to the cylinder and has in this chamber a forwardly directed first piston face of a predetermined first piston area. The first piston is formed with at least one second chamber receiving a forwardly and backwardly displaceable second piston having a forwardly directed end engageable with the first chamber surface. This second piston in turn has a second piston face of a predetermined second piston area substantially smaller than the first piston area and directed backwardly in the second chamber. A liquid under high pressure can be fed alternately to the first and second chambers so that when the first chamber is pressurized the first piston and cylinder will be urged apart with a relatively great force, and when the second chamber is pressurized they will be urged apart with a substantially smaller force.
