Abstract

The externally fitted control device includes an electronic control module (1), a hydraulic control module (2) and a common control enclosure (3). The hydraulic control module (2) has electromagnetic actuators (10) and control pistons (14) which are positioned on top of one another to result in a compact design which is safe to operate and can be manufactured economically.
