Abstract: The invention relates to an actuator for actuating a valve installed in a hydraulic or compressed air system comprising a coil support which can be displaced by means of air space induction in a magnetically conducting housing on a magnetic cylinder composed of a permanent magnet and a cylinder pole disk. The invention is characterized in that the dimensions of the permanent magnet and the pole disk correspond to each other in such a way that the diameter of the front surface of the permanent magnet is at least the same size as the circumferential surface of a neighboring pole disk and that the width of the coil associated with the pole disk exceeds the width of the pole disk by the lift amplitude of the coil support.

The invention is characterised in that the dimensions of the permanent magnet (16) and the pole disk (17) correspond to each other in such a way that the diameter of the front surface of the permanent magnet (16) is at least the same size as the circumferential surface of a neighbouring pole disk (17) and that the width of the coil (23) associated with the pole disk (17) exceeds the width of the pole disk (17) by the lift amplitude of the coil support (19).

Abstract: An assembly machine comprises a machine frame, a plurality of work stations arranged on a circular carrier plate secured on the surface of the machine frame, and a rotary dish that is rotationally driven in cycles and arranged concentrically with the carrier plate. The rotary dish protrudes along the circumference of the carrier plate and forms a ring-shaped support surface for work pieces that surround the carrier plate. The machine frame is a cast machine component that comprises a table-like substructure and a console on the top side with a ring-shaped mounting surface for receiving a drive for the rotary dish. The rotary dish drive is a direct drive that comprises a ring-shaped stator with electrical windings that is secured on the mounting surface, and a rotor fitted with permanent magnets. The rotor forms a carrier for and is detachably connected with the rotary dish.
