Beschreibung
Zusammenfassung:	The invention relates to a pneumatic operating cylinder for operating a tool in linear movement, wherein the operating cylinder comprises: a working cylinder which is divided by at least one piston arranged therein into a least a first and a second cylinder space, wherein the piston is connected to a piston rod onto which the tool is fixed; and control means for controlling the movement of the piston, wherein the control means are connected to a compressed air feed channel and to an air discharge channel, wherein the control means are adapted to connect the compressed air feed channel in a first position to the first cylinder space and to connect the second cylinder space to the air discharge channel via a choke valve, wherein the control means comprise an auxiliary valve which connects the second cylinder space to the discharge channel when the pressure in the second cylinder chamber is less than a predetermined factor times the pressure in the first cylinder chamber; and wherein the control means are adapted to connect the first cylinder space in a second position to the air discharge channel and to connect the second cylinder space to the compressed air feed channel.
