FIELD: automatic control of flow rate of fluid media. SUBSTANCE: invention refers specifically to automatic control devices to feed fuel which present compressed fluid medium into internal combustion engines. Device regulating flow rate of fluid medium has collection of main lines pieced in parallel between common inlet and outlet. Each main line has valve with drive ensuring their selected opening and shutting and pulse mode of operation. Sizes of holes in main lines are so chosen that their capacities so correspond with each other that they are proportional to one of collection. Proportionality factors in this case present power series related to corresponding variant of invention. EFFECT: improved functional reliability of device. 3 cl, 20 dwg
