AIR SEAL BETWEEN RELATIVELY MOVEABLE DUCTS

摘要

AIR SEAL BETWEEN RELATIVELY MOVEABLE DUCTS A seal for interconnecting a vibrating plenum chamber to a stationary air duct for air flow communication therebetween is shown. The chamber defines an inlet duct bounded by an upstream facing annular sealing surface. A baffle member is attached to, and encircles, the adjacent end of the stationary air duct. The baffle member comprises a pair of outwardly converging annular sides sealingly joined at their outer radius, with the innermost annular portion of one side attached to the stationary air duct and the innermost annular portion of the other side attached to a sealing member defining an annular surface slidingly engaging the upstream facing annular sealing surface on the inlet duct.
