Gas-operated drive system and operating method
Abstract
The invention relates to a gas-operated drive system, comprising a drive device (A) comprising a first chamber (1) and a second chamber (2) which are separated from one another by a movable working element (3) of the drive device (A), in particular by a piston (3), one chamber (1) of the two chambers (1, 2) can be connected to a gas source (4), in particular by means of a switching valve (7), to form a chamber (1) for driving the work element (3), and the other chamber (2) of the two chambers (1, 2) can be simultaneously connected to an exhaust opening (6) via an exhaust throttle valve (5), in particular by means of the switching valve, to form a chamber which counteracts the movement of the work element (3), a control valve (8) is associated with the driven chamber (1), by means of which the driven chamber (2) can be filled with gas from a gas source (4), the opening cross-section of the control valve (8) being adjustable as a function of a control pressure which is present upstream of the exhaust throttle valve (5) in the flow direction or which is reduced via the exhaust throttle valve (5), wherein the opening cross-section can be enlarged by means of the control valve (8) when the control pressure drops below a first limit pressure, and the opening cross-section can be reduced, in particular the control valve (8) can be closed, when the control pressure further drops below a second limit pressure. The invention also relates to a method for operating a gas-operated drive system.
