Assembly () comprising an annular turbine distributor () for turbomachinery (), an annular structural element () of the turbomachinery (), coaxial with the distributor () and at least one device () for attaching the annular distributor () with the annular structural element (), characterised in that: &#x2014;the annular distributor () is crossed by at least two axial passages, and &#x2014;the or each attachment device () comprises: at least two pins (), rigidly connected to the annular structural element () and passing through one of said passages of the distributor (), a first transverse stop () for stopping the distributor () axially and passing through two consecutive pins (), and two second stops () rigidly connected to the structural element () to retain, in the pins (), the first transverse stop () for stopping the distributor () radially.

Assembly for a turbomachine comprising a distributor, a structural element of the turbomachine, and an attachment device

A device for controlling clearance at the tops of turbine rotating blades. The device comprises shroud supporting rings, abradable ring sectors, elastic centering elements, and a shroud supporting ring sectors inserted radially to the supporting shroud, between the elastic elements and the abradable ring sectors, which are attached to said supporting shroud, which has a volume varying according to temperature, due to the action of fluid supply elements.
