Abstract
Two rotationally symmetrically correlated components of a turbomachine, such as a gas turbine engine, define between them an air duct surrounding the axis of the components. A resilient band-like wall section extending radially from the first component bears resiliently in an axial direction against a wall section projecting radially from the second component to provide a seal for the duct. Another wall section of each component cooperate to form a radially extending tongue-in-groove joint, which may incorporate another seal for the duct, this joint permitting relative axial and radial movements between the two components. Means may be provided to maintain the fluid pressure within the duct higher than the pressure exterior thereto. The two components may be joined together by a bayonet-type connection. One of the components may comprise two members so that the member carrying part of the bayonet-type connection can be rotated with respect to the other member during assembly of the two components. One of the components may form part of the turbine casing or part of a turbine nozzle, the cooling channels of the nozzle vanes communicating with the air duct. At least some of the abuti…
