Abstract[English]
The invention relates to a sealing device (1) for a flow machine, wherein the sealing device (1) comprises a flap seal (2), a surface (4), a first protrusion (5) protruding from the surface (4), a second protrusion (6) protruding from the surface (4) and a biasing means (3) that is supported on the first protrusion (5) and the second protrusion (6) and is adapted to push the flap seal (2) away from the first protrusion (5) and the second protrusion (6) in a direction transversal to the normal (23) of the surface (4), wherein the biasing means (3) comprises a foot (12) that protrudes from a first region of the biasing means (3) in a direction towards the surface (4), wherein the first region is arranged immediately neighboured to the foot (12), wherein the foot (12) contacts the surface (4) and biases the remaining biasing means (3) in a direction away from the first protrusion (5) and the second protrusion (6).[French]
