Abstract

An apparatus for setting the position of a device provided with a number of hydraulic adjusting cylinders operates by simultaneously supplying to the various cylinders quantities of hydraulic medium corresponding to the desired setting of the device. Each of the hydraulic cylinders communicates with a respective displacement chamber in a hydraulic pump 1 which is common to all hydraulic cylinders. The pump comprises a cylinder 4 and a piston body 3 axially displaceable therein. The piston body 3 is stepped to form a number of annular, concentric piston surfaces 2, and the inner diameter of the cylinder is stepped in a corresponding manner to the piston rod. This results in the formation of a displacement chamber 5 in front of each piston surface 2. The chambers are mutually sealed during a working stroke of the pump and communicate with the cylinders to be set by way of connections 7. <IMAGE>
