Abstract
A pneumatic drive system () in which the movement of an output drive unit () of a pneumatic drive () is controlled by a control valve (and) which is connected with the working chambers (and) of the pneumatic drive (). The control valve (and) comprises least one air economy setting () setting a choke cross section and a high power setting () defining a flow cross section larger than it. An actuator serves to ensure that the control valve is switched over, in a fashion dependent on the air pressure obtaining in the at least one working chamber (and) from the normally assumed air economy setting () into the high power setting (), when the output drive unit () meets with an increased resistance to motion.
