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.

An externally fitted control device comprising:
- an electronic control module (1) and a hydraulic control module (2);
- the electronic control module (1) and the hydraulic control module (2) both being positioned in a common control enclosure (3);
- the common control enclosure (3) being connected fluid tight with a transmission enclosure (9) so as to create a fluid tight space with respect to an external environment in which the electronic control module (1) and the hydraulic control module (2) are positioned;
- and
- the hydraulic control module (2) including control pistons (14), electromagnetic actuators (10), and ducts (16, 17) for guiding pressure or fluid, and the control pistons (14) and the electromagnetic actuators (10) being spaced from one another such that the control pistons (14) are arranged along a first plane (21) and the electromagnetic (10) are arranged along a second plane (20) spaced from the first plane (21).
A hydraulic control module in which the hydraulic control module (2) includes ducts (16, 17), for guiding pressure or fluid, electromagnetic actuators (10), and control pistons (14);
- wherein the hydraulic control module (2) has a first surface (19) by which the hydraulic control module (2) is connectable with a transmission enclosure (9) and by which the ducts (17) guide the pressure or the fluid to the transmission enclosure (9), a first plane (21) is spaced from the first surface (19) and the electromagnetic actuators (10) are arranged along the first plane (21), and a second plane (20) is spaced from both the first plane (21) and the first surface (19), and the control pistons (14) are arranged along the second plane (20).
