摘要： The invention concerns an actuator for a control cylinder (1) whose chamber is divided into two spaces (39, 42) by a piston (52) which is acted on the hydraulic fluid on both sides. In order to permit the complete control unit to be replaced rapidly and without difficulty, removal and mounting being simple and requiring significantly less effort, the invention proposes an actuator in which the actuator element (3) and the control elements (4, 5) which act on the actuator element (3) are fitted in a part (2) of the housing which is flange-mounted on one side of the cylinder (1). This actuator design enables a piston rod (14) to be used which extends out at either end, and the range of applications of the relatively compact design is therefore widened. In a special embodiment of the invention, the actuator is connected to a bus system with a suitable electrical or electronic control unit (6).
