摘要： The invention relates to a device for admitting air to, and extracting air from, an oil tank, having a housing, of which the interior can be connected to the oil tank via a first housing opening and is in flow connection, via a second housing opening, with the exterior space enclosing the housing, wherein a valve body is retained in an axially movable manner between the first and the second housing opening, and this valve body has a first through-passage, which can be closed by a first closure member and can be released by being subjected to a first differential pressure, and, starting from a closing position, in which it closes a second through-passage in cooperation with a second closure member, it can be moved, by being subjected to a second differential pressure, which is directed counter to the first differential pressure, into a release position, in which it releases the second through-passage. In order to develop the device such that the first through-passage can be released in the presence of even a small first differential pressure, it is proposed according to the invention that the first closure member comprises a dome-shaped valve diaphragm which has a sealing region which, by virtue of the valve diaphragm being subjected to the first differential pressure, can be raised up from the first sealing surface and, by virtue of the valve diaphragm being subjected to the second differential pressure, can be pressed onto the first sealing surface.

摘要： The invention relates to a filter device (10) for filtering a liquid, especially a hydraulic oil. The inventive device comprises an essentially cylindrical filter housing (12) which receives a filter element (30) and can be closed by means of a lid (18). Said filter element (30) is associated with a non-treated area (70) having an inlet (22) for supplying liquid to be filtered and a treated area (74) having an outlet (26) for evacuating filtered liquid. The filter element (30) comprises an end disc (58) which faces the lid (18). A radially acting sealing element (62) is held on said end disc and is used to seal the non-treated area (70) of the filter element (30). The aim of the invention is to develop one such filter device in such a way that it can be economically produced and easily mounted. In order to achieve this, the sealing element (62) comprises a radial sealing lip (64) arranged on the inner side of the filter housing (12) and inclined in the direction of the non-treated area (70) of the filter element (30).
