Adverse pressure gradient seal mechanism

摘要

An adverse pressure gradient seal mechanism (100) for use with variable speed components (110) and a method of limiting a leakage flow through variable speed components (110). The adverse pressure gradient seal mechanism (100) may include a number of labyrinth teeth (120) positioned on a component (110) and an adverse pressure gradient seal (130) positioned between a pair of the labyrinth teeth (120). The adverse pressure gradient seal (130) may include a number of strips (140) with each of the strips (140) having an angled end (160).
