ABSTRACT:
A variable geometry device is provided for use in a turbine engine having a support housing, a rotor contained within the support housing and a pair of spaced walls forming an annular and radially extending passageway open at one end to the rotor. An annular recessed channel is formed in one of the support housing walls while a ring is mounted within the channel and movable between a retracted position in which the ring is nested within the channel and an extended position in which the ring protrudes transversely into and variably restricts the passageway so that the restriction of the fluid passageway is substantially proportional to the transverse position of the ring. A plurality of circumferentially spaced vanes are secured to the ring and these vanes extend transversely across the fluid passageway and are slidably received within slots formed in the other support housing wall. In addition, the face of the ring open to the fluid passageway is contoured by meridional constriction for maximum engine efficiency.
