The apparatus has a gas spring (8) with a resiliently compressible gas volume (9). The gas spring is tensioned via a tensioning mechanism (10) by a rotary motor i.e. electromotor (16), to accelerate a setting piston (5) into a setting direction according to release of the gas spring from a tensioned state. A part of the tensioning mechanism is arranged within the gas volume of the gas spring. The motor is arranged outside the gas volume. The tensioning mechanism is connected with the motor via a rotatable shaft (14), and a shaft seal (15) seals the gas volume, and is arranged at the shaft. |
