ABSTRACT:
A linear actuator is provided with a cylindrical bore with internal screw thread and accommodated therein a screw means with external screw thread connected to a rod. By turning these parts with respect to each other, a linear movement of the rod can be obtained. The internal space in the housing is sealed to the outside, and preferably filled with a liquid lubricant. Also, there is a space outside the bore which is connected to the space inside the bore and which is at least partially bounded by a resilient, flexible wall part for compensating volume changes in the bore due to the linear movement of the rod.
