Abstract (en)
[origin: WO2022049298A1] The invention relates to a gas-powered drive system, comprising a drive (A) with a first chamber (1) and a second chamber (2), which are separated from one another by a movable work element (3) of the drive (A), in particular by a piston (3), wherein one chamber (1) of the two chambers (1, 2) can be connected to a gas source (4) to form a chamber (1) driving the work element (3), and the other chamber (2) of the two chambers (1, 2) can be connected at the same time via an exhaust air throttle (5) to a gas sink (6), in particular by means of a switchover valve (7), to form a chamber counteracting the movement of the work element (3), wherein a control valve (8) is assigned to the driving chamber (1), through which control valve the driving chamber (2) can be filled with gas from the gas source (4), wherein the opening cross-section of the control valve (8) can be adjusted depending on a control pressure prevailing upstream of the exhaust air throttle (5) in the flow direction or a control pressure dropping across the exhaust air throttle (5), wherein by means of the control valve (8) the opening cross-section can be made larger when, as the control pressure falls, it falls below a first threshold pressure and the opening cross-section can be made smaller, in particular the control valve (8) can be closed, when, as the control pressure falls further, it falls below a second threshold pressure. The invention also relates to a method for operating a gas-powered drive system.
