Patent ID: 7134667

Claim:
An arrangement for turbo machines having a rotating shaft, a throw-off ring adjacent to a shaft bearing and with a seal adjacent to a sealing gap between the shaft and the seal and having a seal housing, wherein the mutually confronting regions of the seal housing and of the throw-off ring initially run radially and subsequently conically outward and enclose an annular gap between them, the annular gap terminating in a region of the turbomachine not radially aligned with the seal, the mutually confronting regions of the seal housing and the throw-off ring are arranged in such a way that, during the rotation of the shaft, a medium located in the annular gap has imparted to it a turbulent flow, by means of which heavy constituents contained in the medium are centrifuged out, the seal housing has integrally formed on it an annular groove located on the circumference and a projection which extend over the entire circumference, and the mutually confronting regions of the throw-off ring and of the seal housing run so as to diverge from one another.
