Abstract

The present invention relates to a gas turbine engine component includes a static component (64) with at least one first flow channel (74). The labyrinth seal (62) rotates relative to the static component (64). The labyrinth seal (62) is spaced from the static component (64) by a second flow channel (76). The flow passing between the labyrinth seal (62) and the static component (64) will have a first portion that travels through the at least one first flow channel (74) and a second portion that travels through the second flow channel (76) with the first portion of the flow being reintroduced into the second flow channel (76) to create a flow restriction.
