A turbine intermediate case in which a turbine bearing support and an inner case are supported centrally within an outer case by radially inward extending hollow struts. An inner case carrying a diaphragm and seals which defines a vent cavity surrounding a bearing compartment. Air leaking past seals is collected in this vent cavity and flows through the hollow struts to be utilized for impingement cooling of the outer surface of the outer case.
