ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to a flange particularly for a device for separating an aerosol from air.
Published German Patent Application No. DE 3,311,682 discloses an air drying system for a compressed air apparatus driven by a compressor, especially the air-brake apparatus of motor vehicles. It operates with a drying agent which has a limited absorption capacity and has to be changed frequently as liquid accumulates.
Furthermore, German Utility Model No. DE-GM 85/01,736 discloses an air de-oiling element which is constructed as a changeable filter. This means that the coalescer is disposed in a replaceable element. This replaceable element can be fastened to a separator head with a central mounting screw thread. A disadvantage of this known oil separator is that when the coalescer is changed, the entire replaceable element must be removed and replaced with a fresh one. As a result, a large amount of waste, in particular waste requiring special handling, must be disposed of.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an improved device for separating an oil aerosol from air.
Another object of the invention is to provide a device for separating an oil aerosol from air which produces only a small amount of waste material for subsequent waste disposal.
These and other objects of the invention have been achieved by providing an apparatus for separating an oil aerosol from air which comprises a flange which is formed of a rubber-coated metal sheet.
The invention thus relates to a device for separating an oil aerosol from air in which a flange is provided which consists of a rubber-coated sheet metal.
Rubber-coated sheet metal is described, for example, in the literature of EAGLE PICHER Industries GmbH. This document discloses flat gaskets of rubber-coated sheet metal and other sealing materials, as well as noise absorbing plates for motor vehicle brakes etc.
The invention utilizes the advantages of these rubber-covered sheet metals and uses them in a flange which on one hand has a sealing action and on the other hand can be equipped with appropriate fastening means.
In accordance with one preferred embodiment of the invention, provision is made for the use of sheet metal that is coated with rubber on both sides. In this way a sealing action can be achieved on both sides of the flange. The flange is preferably disposed on an annular coalescer. Such a coalescer element is disposed on the one hand between the surrounding housing and a base element.
These and other features of preferred embodiments of the invention, in addition to being set forth in the claims, are also disclosed in the specification and/or the drawings, and the individual features each may be implemented in embodiments of the invention either individually or in the form of subcombinations of two or more features and can be applied to other fields of use and may constitute advantageous, separately protectable constructions for which protection is also claimed.
