Abstract
A drive device comprises a fluid driven drive (2), which defines a drive space (8), in which at least one drive piston (14) is located which is able to be linearly shifted by fluid actuation and is kinematically coupled with an output drive part (17). Furthermore there is a position regulator (3) which is responsible for setting the position of the at least one drive piston (14), such regulator having a electronic regulation circuitry (26) and a valve means (27) and being a component of a regulator cartridge (28) which is inserted as a unitary assembly from the side, which is axially opposite to the drive space (8), through an installation opening into a accommodating space (25) defined by an integral extension of the drive housing (4) made in one piece therewith and axially in sequence with the drive space (8).
