FIELD: engines and pumps.
SUBSTANCE: engine control device, in particular, for car engine equipped with, at least, one control unit (1) for pump (2) output control, which pumps medium along working line (4) to working area (5), wherein control unit (1) includes actuating cylinder (9), connected by control line (10) with working area (5), and available there medium operating pressure acts as supply force FZ acting on actuating cylinder (9) when supplying actuating cylinder (9), wherein return force FR from return unit (11) acts on actuating cylinder (9), which counteracts supply force FZ, wherein return unit (11) includes pressure line (12) with throttling action, at which flows medium, and return force FR is, at least, partially result of pressure in pressure line (12), wherein pressure line (12) is preferably connects pump (2) discharge side (13) and supply side (14).
EFFECT: higher reliability.
