Patent ID: 7360989

Claim:
A device for axially holding a ring spacer sector of a high-pressure turbine of a turbomachine, wherein said spacer sector comprises: an upstream radial wall provided with an outer upstream tongue for being engaged in a corresponding upstream groove of a casing of the high-pressure turbine, and with an inner upstream tongue for being engaged in a corresponding upstream groove of a ring sector; and a downstream radial wall provided with an outer downstream tongue for being engaged in a corresponding downstream groove of the casing of the high-pressure turbine, and with an inner downstream tongue for being secured to the ring sector; the device comprising a piece of longitudinally-extending sheet metal that constitutes a heat shield disposed upstream from the upstream radial wall of the spacer sector against an inner surface of the casing, wherein the piece of longitudinally-extending sheet metal bears axially against the upstream radial wall of the spacer sector and is secured to the casing so as to hold the spacer sector axially.
