ABSTRACT:
An electric control device in the form of a final control element for fuel injection pumps for internal combustion engines is protected in the interior of its housing from having the parts it contains inundated by lubricant originating in the interior of the injection pump. This protection is effected in that a suction device driven by the camshaft is disposed in the interior and aspirates lubricant originating in the injection pump and returns it then. The suction device has a rotating part driven by the camshaft, and at its lowest point in the sump it has a sliding shoe which under spring pressure rests at the rear on the rotating part and is so embodied that lubricant adhering to the rotating part reaches a gap and from there is transported back into the injection pump via a drainage hose containing a check valve.
