FIELD: engines and pumps.
SUBSTANCE: proposed assembly arranged between rotary and fixed turbine components comprises: at least, one seal ring fitted on fixed component to move to and from rotary component between open and closed positions depending upon pressure difference at seal ring, and fluid overflow circuit to direct fluid flow around, at least, one seal ring to reduce said pressure difference so that said seal ring moves into open position driven by, at least, one or several springs or actuators.
EFFECT: higher reliability.
