Abstract (en)
[origin: EP0771953A2] The linear drive has a housing (2) with an elongated running chamber (6) for a piston (13), which can be moved longitudinally (7) by a fluid. A driven component (16) is arranged outside the piston in a circumferential region of the chamber, and can be braked and/or fixed relative to the housing by equipment (34) which has a threaded spindle (35). The spindle is arranged parallel to and outside the chamber, and extends at least along the maximum possible stroke path of the component, with a rotary mounting on the housing on each axial side of this path. The spindle engages with an internal thread (42) on the component which is rotated due to its reciprocating motion. A brake unit (44) is arranged in an end region of the housing, and works together with a brake part (46) which is fixed to the spindle outside the path, in order to influence the rotary motion of the spindle.
