FIELD: machine building.
SUBSTANCE: device provides for installation of the drain nozzle in the liquid-liquid ejector of the confusor-diffuser type with perforated diffuser with screen, having device of angular rotation relatively to axis of the drain nozzle, rotation drive, at that rotation of screen changes area of the perforated surface of the diffuser, through its perforation the flow exit the ejector to tank. The drive of screen rotation has automatic regulator, for example, spring.
EFFECT: increased efficiency of liquid degassing by intensification of the degassing process.
