ABSTRACT:
The invention is a valve seal assembly (43) illustrated in the context of a compressor bleed valve (36) for a gas turbine engine. The seal assembly includes a seal carrier (44) having a circumferentially extending groove (72) bordered by a pair of opposing flanges (74). The flanges cooperate to define a recess (76) portion of the groove and a throat (78) portion of the groove. The seal assembly also includes one or more seal elements (46) each having a base (82), conformal with the recess, and longitudinally captured in the recess by the flanges. A stem (84) extends from the base and projects through the throat, and a sealing bead (86) extends from the stem. An insert (88) extends circumferentially in the base for stiffening the base about a circumferential bending axis (C). An access port (96) facilitates installation and removal of the seal elements (46) and a cover (98) traps the seal elements in the carrier (44). During operation of the valve, shearing forces act on the seal elements as the valve approaches its fully closed position. The flanges and the stiffness of the insert resist any tendency of the shearing forces to peel the seal element out of the groove.
