Fluid-actuated contraction drive and associated contraction tube

摘要

A fluid power contractile drive comprising a contractile hose (2), which on fluid actuation of an actuation space (7) delimited by it undergoes longitudinal contraction and which at its two terminal regions (5 and 6) is adapted to be, or is, provided with a force output means (8) rendering possible output of the drive force produced. At one terminal region (5 and 6) at least the contractile hose (2) possesses a flat configuration and is bent over, the hose sections (18 and 19) of the hose sections being placed adjacent to each other owing to such bending over being connected firmly with each other.
