Abstract (en)
[origin: WO2007068416A1] Within the scope of the method for reducing the mechanical loading and for increasing the operating speed during the actuation of an operating piston, in particular the operating piston of an operating element, that side (opposite side) of the operating piston (1) which is remote from the adjusting pressure is ventilated in a defined manner by means of a counter ventilation pulse in such a way that the maximum possible ventilation pressure in the operating cylinder (2) cannot build up, wherein the duration and the amplitude of the counter ventilation pulse are defined in such a way that a quicker piston movement can be realized while at the same time achieving sufficient end position damping.
