Abstract
The present invention relates to a turbine assembly with a basically hollow aerofoil, having at least a cavity with an inner wall and having at least an aperture providing access to the cavity, and at least a first impingement device arrangeable within the cavity. The at least first impingement device is self-locking, resilient and preloadable and has at least one locking element to lock the at least first impingement device in place in the cavity via a force fit between the at least one locking element and the inner wall of the cavity wherein the locking element of the at least first impingement device is embodied as a protrusion extending in an assembled state of the at least first impingement device in the cavity basically perpendicular to a surface of a side wall of the at least first impingement device in a direction towards the inner wall.

14. A turbine assembly comprising
a basically hollow aerofoil, having at least a cavity with an inner wall and having at least an aperture providing access to the cavity, and at least a first impingement device arrangeable within the cavity, wherein the at least first impingement device is self-locking, resilient and preloadable and has two locking elements to lock the at least first impingement device in place in the cavity via a force fit between each one of the two locking elements and the inner wall of the cavity wherein the at least first impingement device has at least two side walls with the two locking elements of the at least first impingement device are embodied as protrusions each processed by a bending of an end region of the side walls basically perpendicular with an angle of approximately 90° - to a surface of each side wall, wherein the surface faces the inner wall and is arranged basically in parallel to the inner wall, therefore each protrusion extends in an assembled state of the at least first impingement device in the cavity basically perpendicular with an angle of approximately 90°
to the surface of each side wall of the at least first impingement device in a direction towards the inner wall. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
