Claim Text:
1. A turbine, comprising: a first inner wall; a second inner wall; an inner casing, and a shield element; wherein the first inner wall and the second inner wall are mounted to the inner casing, wherein the first inner wall and the second inner wall are arranged such that an inner volume, through which a working fluid of the turbine is flowable, is separated from an outer volume, through which a cooling fluid is flowable, wherein the first inner wall, the second inner wall and the inner casing are arranged with respect to each other such that a cavity is formed in the outer volume, wherein the shield element is arranged inside the cavity such that the shield element separates the cavity in an inner region and an outer region which is formed in a radially outer position in comparison to the inner region, wherein a gap is formed between the first inner wall and the second inner wall, through the gap the working fluid is flowable between the inner volume and the inner region, and wherein the shield element is arranged in the cavity such that a fluid inlet is formed, through which the cooling fluid is injectable from the outer region to the inner region for generating a predefined recirculation of the working fluid and the cooling fluid inside the inner region.
