Patent ID: 7445426

Claim:
A compressor stator comprising: a casing having a circumferential slot for mounting a plurality of vane sectors; a vane sector having an outer shroud with a means to hold the forward section of the outer shroud to a forward section of the slot, and a means to hold the rearward section of the outer shroud to a rearward section of the slot; the vane sector comprising a forward guide vane and a rearward guide vane extending from the outer shroud; an inner shroud forming a gap between a tip of the forward guide vane and a gap between a tip of the rearward guide vane; the slot including a space to allow for the outer shroud to move radially when the rearward guide vane tip contacts the inner shroud due to thermal growth of the stator; and, a spring means located substantially in the rearward section of the slot and outer shroud to bias the rearward guide vane toward the inner shroud and allow the space between the slot of the outer shroud to shrink when the rearward guide vane tip contacts the inner shroud.
