Gas turbine engine seal assembly having flow-through tube

摘要

A seal assembly (54) for a gas turbine engine includes an annular body (56) and a flow-through tube (58) that extends through the annular body (56). The flow-through tube (58) includes an upstream orifice (86), a downstream orifice (88) and a tube body (84) that extends between the upstream orifice (86) and the downstream orifice (88). The tube body (84) establishes a gradually increasing cross-sectional area between the downstream orifice (88) and the upstream orifice (86).
