ABSTRACT:
A control device for a door closer is arranged to control flow of pressure medium within a body part of the door closer and comprises an adjustment member supported by threads on the body part of the door closer, and in cooperation therewith, a separate substantially hollow control member, which is arranged to restrict the flow of the pressure medium when necessary. Turning of the adjustment member with respect to the body part of the door closer brings about movement of the control member in the axial direction of the control device for providing the desired control. The control member is arranged to be attached to the adjustment member in the radial direction so that movement of the control member with respect to the adjustment member in the axial direction is prevented.
