Abstract

The linear drive device (1) has a linear drive (10) with end-position damping by damping devices (35), and two working chambers (12a, 12b). The venting of the downstream working chamber (12a) is controlled through a pressure-limiting valve device (47). Venting takes place only when a preset minimum pressure exists in the downstream working chamber, producing an independent end-position damping effect when required.
