Abstract: The invention relates to a drive, especially for rotary, pivotal or linear drive units, comprising a working piston (16), housed in a cylinder (12) of a housing (14), impinged by fluidic pressure media and displaced in the axial direction. The invention is characterized in that mechanical coupling elements (22, 24) are disposed on the working piston and can be coupled with a motor (30) in such a manner that the motor slows down and/or drives the working piston in the axial direction. The invention also relates to rotary, pivotal or linear drive units comprising said drive and to a method for operating a drive or a rotary, pivotal or linear drive unit.

Abstract: The invention relates to a gear mechanism (40), in particular a linkage mechanism, having a base unit (42) and a rotational unit (44) which is mounted such that it can be rotated relative to the base unit about an articulation axis (46; 18), wherein the base unit has a drive element (48; 10) which can be driven rotationally, in particular, perpendicularly with respect to the articulation axis, having two rotationally mounted rotary members (54, 56; 14, 16) which can be driven in opposite directions by the drive element and are arranged, in particular, coaxially with respect to one another, wherein each of the rotary members drives a coupling element (60, 62; 30, 32) which is operatively connected to it when the drive element is rotating, wherein the two coupling elements are arranged such that they are mounted rotatably in a cage (68) of the rotational unit and are operatively connected to one another in such a way that, and wherein the drive body is operatively connected to the rotary members, the rotary mem
