Linear Actuator

A linear actuator having a threaded drive including a nut connected to a cantilever tube and a leadscrew coupled to a motor, so that, by rotation of the leadscrew, the threaded nut and the cantilever tube are linearly movable, and, regardless of the position of the cantilever tube, one end the leads...

Beschreibung
Zusammenfassung:	A linear actuator having a threaded drive including a nut connected to a cantilever tube and a leadscrew coupled to a motor, so that, by rotation of the leadscrew, the threaded nut and the cantilever tube are linearly movable, and, regardless of the position of the cantilever tube, one end the leadscrew projects into the cantilever tube and is connected to a piston which divides an internal space formed by the cantilever tube into a first region on the side of the piston opposite the threaded nut and a second region on the side of the piston facing the nut. The two regions are separated from one another in a fluidically sealed manner. A relief of the threaded drive is improved since the first region is connected to a pressure accumulator to generate a relief pressure in the first region using the first pressure source.
