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.
