Abstract
A drive device serves for adjusting an operating element for a valve, a throttle, a blow-out preventor or the like, in particular in the field of gas and oil production, the operating element being actively connected to at least one driving motor via a drive train, and at least one transmission changing unit being arranged in the drive train for converting a revolution of the driving motor into a revolution of the operating element and/or a revolution/linear motion converter being arranged for converting the revolution of the driving motor into a linear motion of the operating element. In order to also have a very compact design in case of a high possible performance and to simultaneously permit a good thermal distribution within the drive device, so that separate cooling devices for carrying off the generated lost heat are superfluous, the drive train comprises at least one essentially disk- or wheel-shaped revolution introducing device which is actively connected with at least two drive shafts driven by separate driving motors.
