A DEVICE IN AN ACTUATOR FOR ELEVATION ADJUSTMENT OF WORK STATIONS

摘要

An actuator for variable adjustment of the pistons in hydraulic slave cylinders for regulation of for example the elevation adjustment of work stations. The pistons are actuated by way of a pusher which is non-rotatable but axially displaceable in the actuator housing (10). In the housing (10) there are provided one or more oblong openings (22) for drivers (27) attachable to the pusher and arranged for cooperation with the corresponding pusher in one or several further actuators placeable close to the actuator and that in at least one of the connected actuators there is arranged a threaded spindle for cooperation with a pusher designed as a nut.
