Abstract

To limit the extension of its displaceable parts, in particular the telescopic tubes (14, 15) and the piston (16), the actuator has conventional stop rings (23, 28) of round spring steel. Intermediate stop rings (35) lying between them in the stop position are provided in order to reduce the radial forces. <IMAGE>
