ABSTRACT:
A ring or other annular assembly is supported within a compressor casing by means of one or more resiliently deformable bodies of elastomeric material adhered between two rigid plates. One of the rigid plates is secured to the ring, the other to the compressor casing, and both plates are disposed parallel to the direction of movement of the ring. Preferably, the resiliently deformable body is made up of an alternating stack of the elastomeric plates and rigid plates adhered together, and parallel with the first two rigid plates which secured the body to the ring and the casing. A compressor of a gas turbine plant incorporates an antisurge blow-off valve mechanism in the form of a slot formed in the outer wall defining the flow path and an annular assembly movable axially of the plant to close and open the slot.
