Abstract
A sealing arrangement (100) in an axial turbomachine between, on the one hand, a rotor (1) and, on the other hand, a stator (3) and/or a housing, including a support device (7, 7′) and a sealing element, whereby the support device (7, 7′) extends essentially in the radial direction (r). In the axial direction (u) of the turbomachine, the support device (7, 7′) has an axial contour that effectuates a stiffening effect for the support device (7, 7′).
Claims19
A sealing arrangement between:
- (a) a rotor and (b) a stator or a housing, the sealing arrangement comprising:
- a support device;
- a holding plate;
- and
- a seal element comprising a wire with bristles wrapped around the wire and a clip holding the wire and bristles together located between the support device and the holding plate, the clip having an inner surface contacting the bristles and an outer surface contacting the support device;
- the support device extending radially, and, in the axial direction of the turbomachine, having an axial contour stiffening the support device;
- wherein the support device or the seal element is configured so as to be ring-shaped or segmented in the circumferential direction, wherein the support device is configured so as to have a wavy or zigzag shape in a developed view.

A sealing arrangement between:
- (a) a rotor and (b) a stator or a housing, the sealing arrangement comprising:
- a backing plate;
- and
- a seal element backed by the backing plate, the seal element comprising a wire with bristles wrapped around the wire and a clip holding the wire and bristles together;
- the clip having an inner surface contacting the bristles and an outer surface contacting the backing plate;
- the backing plate extending radially, and, in the axial direction of the turbomachine, having an axial contour stiffening the support device;
- wherein the backing plate or the seal element is configured so as to be ring-shaped or segmented in the circumferential direction, wherein the backing plate is configured so as to have a wavy or zigzag shape in a developed view.
