Abstract

A wheel member (20, 21, 22) includes a body (50) having a first surface (54) that extends to a second surface (55) through an intermediate portion (56). The body (50) includes an outer diametric surface (58) and a central bore (60). A first plurality of purge circuits (64) are formed in the body (50). The first plurality of purge circuits (64) extend from a first end (74) to a second end (75) through the body (50). The first plurality of purge circuits (64) are arranged to direct a first purge flow (80) in a first direction. A second plurality of purge circuits (68) are formed in the body (50) and fluidly isolated from the first plurality of purge circuits (64). The second plurality of purge circuits (68) extend from a first end portion (85) to a second end portion (86) through the body (50) and are arranged to direct a second purge flow (95) in a second direction, that is distinct from the first direction, to establish a cross-over purge flow system (45).
