A hydraulic control device having a hydraulic actuator with a cylinder space, in which a piston is accommodated. In the cylinder space the piston bounds a first chamber and second chamber. The housing is provided with a first and a second connection for the supply and discharge of hydraulic fluid, in communication with the first and the second chamber by way of a first and a second opening. The damping means are achieved by the fact that the piston is provided with shut-off means, which are designed to shut off the second opening of the cylinder space before the piston/piston rod assembly reaches an end position. The hydraulic actuator is further provided with a third connection, which by way of a third opening is in communication with the second chamber in any position of the piston. The hydraulic control device further comprises a throttling facility.
