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. According to the invention, the actuator for actuating a valve used in fluidic engineering is disposed in such a way that the coil support is displaceable in a fluidic medium and the air gap arranged between the coil support and a magnetic cylinder pipe surrounding the permanent magnet and the associated pole disk has a maximum width whereby a laminated lubricating film is formed without displacing the surrounding fluid.
