Abstract

A retainer for non-rotatably retaining a conduit member that extends through an opening in a casing wall. The retainer has an annular top wall that includes an inner periphery having inwardly extending projections to engage the outer surface of the conduit member. Additionally, the retainer includes a depending skirt that extends from the outer periphery of the top wall. A pair of outwardly extending straps extend from the skirt and include bolt holes for enabling the retainer to be bolted relative to the casing wall. The retainer limits axial outward movement of the conduit member and also diffuses and deflects any leakage air that passes around the conduit member to avoid impingement of the leakage air against the structural components and accessories that are positioned outside the engine casing.

Claims14

Dependent claims

A retainer for retaining a conduit that extends through a gas turbine engine casing wall, said retainer comprising:

a. an annular top wall having an outer edge and an opening having an opening axis and including a plurality of contact surfaces for cooperative engagement with a conduit member to be retained;
b. a depending skirt extending from the outer edge at one face of the top wall and having a predetermined length in a direction of the top wall opening axis, the skirt terminating at a free end;
c. at least two circumferentially-spaced legs extending from the free end of the depending skirt in the direction of the top wall opening axis, each leg extending in a circumferential direction relative to the top wall opening for a predetermined circumferential distance to define circumferentially spaced passageways between the respective legs and the free end of the skirt to allow flow through the passageways of gas leakage from within the casing wall;
and
d. a radially-outwardly-extending tab carried by each of the at least two legs, each tab including a bolt opening for receiving a connecting bolt for attaching the retainer to a wall through which the conduit member extends.
