A flow machine is described having a first space adapted to contain a hot fluid and delimited by a wall. The wall having a first wall surface facing the first space and a second wall surface turned away from the first space. Cooling is provided for a region of the wall by supplying a relatively cool fluid onto the second wall surface. The cooling means includes a supply chamber containing the second fluid, a cavity adjacent the second wall surface, at least one duct, which has an inlet opening at the supply chamber and an outlet opening at the cavity for conveying the cool fluid to the cavity, and a deflection surface facing the cavity. |
