Textile machine according to paragraphs. 1 or 2, characterized in that an actuated decompression valve (72) is connected to the gas chamber (64, 120).  4. Textile machine according to one of paragraphs. 1-3, characterized in that a safety valve is connected to the gas chamber (64, 120).  5. Textile machine according to one of paragraphs. 1-4, characterized in that the gas chamber (64, 120), preferably through a check valve (68, 124) is connected to a source of compressed air (70, 126).  6. A textile machine according to claim 5, characterized in that the compressed air source (70, 126) has a control device (74) connected, preferably, to a control device (76) of the textile machine, with which it is possible to adjust the gas pressure (P ) in the gas chamber (64, 120) depending on the operating condition of the textile machine. 7. Textile machine according to claim 6, characterized in that the control device (74) is configured so that the pressure (P) in the gas chamber (64) can be set as follows as the pressure P _I in the working phase I of the product change of the textile machine, which corresponds to ambient air pressure P _O ; the pressure P _II in the acceleration phase II, which is at least equal to the gas pressure P _III in the high-speed phase; the gas pressure P _III in the high-speed phase III, which is less than or equal to the gas pressure P _II in the acceleration phase II; the gas pressure P _IV in the creeping stroke phase IV, which is less than the gas pressure P _III in the high speed phase III; and the gas pressure P _V in the phase of the manual drive V, which is equal to or less than the gas pressure P _IV in the creeping stroke phase. 8. Textile machine according to one of paragraphs. 5-7, characterized in that it is designed so that the gas pressure (P _E ) with expanded gas in the gas chamber (64) corresponds to the gas pressure (P _Q ) in the source of compressed gas (70). 9. A textile machine according to claim 8, characterized in that it is designed so that the gas pressure (P _K ) in the gas chamber (64) in a compressed final state corresponds to the formula

where P _E means the gas pressure of the expanded gas volume in the gas chamber;
V _E is the gas volume of the gas chamber in the expanded state;
V _K is the volume of gas in the gas chamber in a compressed state. 10. The textile machine according to claim 9, characterized in that it is designed so that the gas pressure (P _K ) in the compressed final state is P _K ≅ 100 + P _E.  11. Textile machine according to one of paragraphs. 2 - 10, characterized in that the part of the cylinder (62) located on the second side of the piston (60) is made as a gas chamber and is connected to a pressure control device (86) so that the gas pressure (P) in the second gas chamber (84) supports and / or inhibits the action of the first gas chamber (64).  12. Textile machine according to one of paragraphs. 1 to 11, characterized in that it is designed as a weaving machine, and at least the shedding device is equipped with a pneumatic actuator (36) with a power circuit.  13. Textile machine according to one of paragraphs. 1-11, characterized in that it is designed as a knitting machine, preferably as a warp knitting machine, with at least one yarn folding lever (92), preferably the yarn folding lever is equipped with a pneumatic actuator (112) with a force closure.
