Patent attributes
Hydraulic actuating device comprising a first and a second hydraulic actuator, which actuators have a first and a second connection for the supply and discharge of hydraulic fluid, which connections are in communication with a first and a second chamber, respectively, by way of a first and a second opening, respectively, in the cylinder space. The first opening of the second hydraulic actuator is in communication with the first opening of the first hydraulic actuator. The second opening of the second hydraulic actuator is in communication with the second opening of the first hydraulic actuator via a third connection. The third connection is in communication with the cylinder space in the first hydraulic actuator via a third opening. Damping means are achieved by a restriction of the outflow of hydraulic fluid via the second opening before the piston/piston rod assembly reaches the second end position.
