FIELD: machine building.
SUBSTANCE: high pressure turbine includes an outer housing, a distributor, a blade wheel, an assembly forming a ring and arranged in a circumferential direction of rotating blades, a control device of radial gap between tips of rotating blades and the ring, as well as an annular support and an annular shock absorbing element. The distributor is formed with a row of guide vanes, and the blade wheel is installed on its exit side. Radial gap control device includes a control chamber with annular chambers, which is attached to the outer housing at least at two points at some distance from each other. The annular support supports the ring and is attached to the outer housing of the turbine. The annular shock absorbing element has the specified elasticity; one of its ends is fixed on the annular support, and the other end is borne in axial direction against the inlet side of the control chamber to provide shock absorption at least of some part of vibrations of the chamber, which occur at operation of the turbo-machine. The other invention of the group refers to a turbo-machine containing the above turbine.
EFFECT: inventions allow increasing service life of a radial gap control chamber.
