Motor-fluidic drive, especially for rotary, pivotal or Linearaantriebseinheiten and method therefor

The invention relates to a drive, especially for rotary, pivotal or linear drive units, housed in a cylinder with a a housing can be acted upon by fluid pressure means and movable in the axial direction of the working piston. The invention is characterized in that mechanical coupling means are arranged on the working piston, which are so coupled with a motor, that the working piston can be braked by the motor in the axial direction and / or driven. The invention also relates to a rotary, pivotal or linear drive unit with such a drive as well as a method for operating a drive or a rotary, pivotal or linear drive unit.
