Patent ID: 7665958

Claim:
A heat accumulation segment for local separation of a flow duct inside a turbo engine, from a stator housing that radially surrounds the flow duct, the heat accumulation segment comprising two axially opposed joining contoured elements that are engageable with two components that are axially adjacent along the flow duct, a first one of the two joining contoured elements has a radially oriented recess with a contoured surface against which a securing pin having an external contour complementary to the contoured surface acts radially under force action from a component that adjoins the first joining contoured element, and the first joining contoured element has a collar portion, having radially upper and lower collar surfaces, and the collar portion is connected within a counter-contoured receiving contoured element in the axially adjacent component by a joining force that acts between the securing pin and the contoured surface of the heat accumulation segment, wherein the radially oriented recess has a half shell form having half a cylindrical contoured surface, and the half cylindrical contoured surface axially faces the collar portion.
