Linear Actuator - A simplified explanation of the abstract
This abstract first appeared for US patent application 18462555 titled 'Linear Actuator
Simplified Explanation
The linear actuator described in the patent application consists of a screw drive system with a threaded nut connected to an extension arm tube and a threaded spindle coupled to a motor. The spindle has a piston at one end that divides the interior space of the tube into two regions separated by a fluid-tight seal. The nut acts as an annular piston that creates an annular fluid space between the housing of the actuator and the tube, which is the same size as one of the regions. A switching valve connects the first region and the annular fluid space, allowing for controlled movement of the piston within the tube.

Original Abstract Submitted
A linear actuator has a screw drive having a threaded nut connected to an extension arm tube and a threaded spindle couplable to a motor. A first end of the spindle always projects into the tube and is connected to a piston which partitions an interior space formed by the tube into a first region on the side of the piston opposite to the nut and a second region on the side of the piston facing the nut. The regions are separated in a fluid-tight manner. The spindle is held in position since the nut comprises an annular piston that delimits an annular fluid space between a housing of the linear actuator and the tube in a fluid-tight manner, the hydraulically effective surface of which is the same size as that of the first region. The first region and the annular fluid space are fluidically connected by a switching valve.
