Control method for traveling motion in a piston on a pneumatic actuator in a final position uses a piston to separate a space for motion in an actuator's casing into chambers

摘要

Triggered by a control module (14), a valve system (13) adjusts pneumatic pressure in chambers (18,19) for a braking phase, in which a piston's (15) speed is reduced by braking, and for a crawling phase linked to the braking phase, in which a piston travels towards a final position at a crawling speed. A braking time point is altered, at which a braking phase begins during the piston's traveling motion before reaching a final position.
