Sealing device for a pressure case used in a rotary machine

---

Abstract

---

A sealing device, which is situated between a rotary cylinder and the opposite edge of a wall of a pressure case, is used in a rotary machine and comprises a seal fitted over its whole length along an edge of a wall, which is parallel to the axis of rotation of the cylinder, and the wall is shifted toward the cylinder by a pressing arrangement so as to enable the seal to be applied against the cylinder. Specifically, the seal has the shape of at least one lengthwise brush with the bristles, which consist of a relatively flexible and heat-resistant material, which is preferably a synthetic material.
