A control mechanism for a door of a motor vehicle is suggested that is coupled at a door post on the side of the body so that it can be swung, is actuated via an inside and outside handle and comprises a piston-cylinder unit arranged between the door post and the vehicle door. The unit has a piston provided with passage openings for a pressure medium, the piston interacting with an interior valve that separates two working chamber of the cylinders from one another. The mechanism has an exterior blocking valve controlling the medium flow, this blocking valve being arranged in a control circuit connecting the two working chambers of the cylinder, acting against the flow direction. The blocking valve is controlled by a door handle in such a way that the door can be blocked in at least one intermediate position. The interior valve is held on the piston under the tension of a spring in such a way that when the vehicle door is opened, the passage openings are closed, and when the vehicle door is closed, the passage openings are passable for the medium. The blocking valve is controlled in such a way that, when the door handle is actuated, it takes up a release position, and when the door handle is not actuated, it takes up a closing position in the control circuit. |
