ABSTRACT:
A ring of an annular valve assembly is movable in the direction of its longitudinal axis and is intended for an axial compressor blow-off arrangement. The ring takes the form of an axially orientated channel-section member having a first annular skin of concave section nested in a second annular skin also of concave section. A cavity filled with a synthetic resin filler is defined by the two skins. The blow-off arrangement for an axial-flow compressor of a turbo-jet engine, which incorporates this ring, comprises an annular opening with which the ring cooperates to re-form the wall of the air flow when the blow-off arrangement is inoperative.
