Abstract: The invention relates to a device for separating media, in particular for removing gases, such as air, from a fluid, such as oil, comprising a separating apparatus (10), which causes the medium to rotate upon entering the separating apparatus for the purpose of carrying out the separation and which has one outlet point (14, 12) each for the gas and for the fluid, said outlet points being separated from each other, wherein the device for separating media is characterized in that the separating apparatus (10) has a bypass valve (16), which is arranged downstream of the fluid flow and upstream of the outlet point (12) for the fluid and through which at least part of the medium flows to the outlet point (12) for the fluid in order to bypass the region of the separating apparatus (10) designed to remove gas front the fluid, provided the medium in the vicinity of the bypass valve (16) exerts a pressure sufficient to open the bypass valve (16).

Abstract: The invention relates to a filter apparatus, especially intended for incorporation into a fluid reservoir tank (10) with at least one preferably exchangeable filter element (18) through which fluid can flow from the inside outward and which is surrounded, in each case maintaining a presettable radial distance and with formation of a fluid flow space (66), by a housing wall (44) which has a plurality of passage sites of which some are arranged below the particular adjustable fluid level (68) in the reservoir tank (10) and the rest are arranged above this fluid level (68). The invention further relates to a filter element for this kind of apparatus.
