FIELD: machine building.
SUBSTANCE: volume booster for fluid flow control device comprises feed path for feeding additionally injected fluid to facilitate actuating drive in first direction and outputs a path for controlled discharge to facilitate drive actuator in second direction. Feed path specifies inlet resistance, which is set by geometry of feed control component. Discharge path includes discharge resistance set by geometry of carrier control component. Feed and discharge control components are detachable and replaceable on replaceable components independently from each other for adjustment of carrier and input resistance and, consequently, outgoing and supply power for specific applications.
EFFECT: higher reliability of flow control device.
