Definitions

  • the invention relates to an actuator with the features of the preamble of claim 1.
  • a generic actuator is known (DT-OS 21 03 701).
  • the piston working element of this single-acting actuator is moved by means of an electrically driven pump with oil drawn in from a sump against the force of a return spring from a rest end position to an extended work end position and can only be held there as long as the drive motor and the pump are running.
  • all the functional parts of this known actuator are housed in one housing, this is not very small because of the necessary oil sump. Actuating forces can only be applied in one working direction.
  • the invention has for its object to provide a generic actuator with fluid power transmission so that when using atmospheric air as a working medium, a simple structure, high actuating forces with small dimensions and small moving masses and short positioning times between the two end positions of the actuator can be achieved.
  • An actuator has an electric motor 1 with electrical connections 2 and 3. This is inserted into a housing 4, which in turn consists of two housing parts 5 and 6.
  • the actuator By means of a bore 22 in the housing part 5, the actuator is fastened in the vicinity of a closure connected to the actuator or a fan flap or the like to be moved into the open or closed position.
