Piston rod-less pneumatic cylinder

A piston rod-less pneumatic cylinder which comprises:

• a cylinder tube which has a longitudinal slot extending from an outer surface to an inner surface thereof, first and second walls of said cylinder tube providing said longitudinal slot defining longitudinally-extending sealing areas at respective inner portions thereof,
• a piston located in said cylinder tube and longitudinally movable therein,
• a transmission element located outside said cylinder tube and connected through said longitudinal slot to said piston to be longitudinally movable with said piston,
• a sealing tape positioned in said cylinder tube to seal said longitudinal slot longitudinally of a location of said piston, said sealing tape including a longitudinal sealing strip which is positionable against said longitudinal sealing areas of said first and second walls of said cylinder tube, said sealing tape including a longitudinal fixing strip which extends into said longitudinal slot, and
• an outer band located on the outer side of said cylinder tube to seal said longitudinal slot in a longitudinal direction, said outer band including first and second spaced longitudinal fixing elements which can, solely by frictional engagement with opposite first and second lateral fixing areas of said longitudinal fixing strip along portions thereof where both said longitudinal sealing strips and said outer band contact said cylinder tube, seal said longitudinal slot,
• said sealing tape and said outer band passing through channels in said piston.
