摘要： A filter device for filtering fluid particularly an aqueous urea solution, includes a filter housing (1), a filter element (11) and a compensating element (31) for compensating fluctuations in the pressure and/or volume of the fluid. At least one elastically-flexible membrane (31) serves as the compensating element. The membrane wall of of the membrane is held in a retaining part (35) and maintains a separation between the fluid and a compressible filling medium such as a working gas.

摘要： A filter device has a filter element (3) in a filter housing (1). Corresponding threads (23, 33) form a screw connection between a housing cover (5) of the filter housing (1) and the filter element (3). A seal (29, 35) is between the filter element (3) and the housing cover (5). The screw connection is formed by threads (33) on a connecting pipe piece (31) that is part of an end cap (17) of the filter element (3) and that extends into the inner filter cavity (22) and by the threads (23) of the housing cover (5). The housing cover threads (23) are on a receiving pipe piece (21) formed by a separate component attached to the housing cover (5).

摘要： An assembly forms a seal between components (11, 33) having sealing zones (37,51). The sealing zones face each other in a functional position of the components. A sealing element (43, 57) is on the sealing zone (37, 51) of one component (11, 33). A sealing surface (51) is on the sealing zone (37, 51) of the other component (11, 33) to form a radial seal. The components (11, 33) can be brought into the functional position by a relative movement in the axial direction. The sealing element (43, 57) sealingly interacts with the sealing surface (51) in the functional position. A third component (61) associated with an actuating part (62) acts on the sealing element (43;57) in the functional position of the components (11, 33) to deform the element to increase the sealing force.

摘要： The invention relates to a filter device with a filter element (1) which can be received in a filter housing that consists of at least two interconnectable housing parts (17, 19). The filter element (1) can be fixed to a housing part (19) in a removable manner by means of a screw connection (32, 33), and an additional screw connection (17, 41) is provided for connecting the housing parts (17, 19). The invention is characterized in that in order to transmit a torque between threaded elements (33) of the screw connection (32, 33) and of the additional screw connection (41), said threaded elements being rotatable relative to each other, a coupling device (43, 46, 61) is added which allows an additional rotational movement of the threaded element (17) of the additional screw connection (41) when the threaded element (33) of the screw connection (32, 33) reaches the fixed rotational state.

摘要： A filter device, having a filter housing (1) which has a filter head (3), a filter pot (7) and a removable housing cover part (51) and which accommodates a filter element (13) which separates a non-filtrate side (15) from a filtrate side (17), and having a bypass valve device which has a valve closure element (65) which is preloaded by means of a closing spring (69) into a closed position in which it bears against a valve seat part (74) and which, if the filter element (13) is blocked, passes into a position in which it opens up a fluid path from the non-filtrate side (15) to the filtrate side (17), by passing the filter element (13), is distinguished by the fact that the valve closure element (65) and the closing spring (69) are arranged on the cover part (51) and the valve seat part (74) is situated on an element cap (43) of the filter element (13), which element cap has a receiving part (45) which forms an enclosure for that end of the filter material (27) of the filter element (13) which faces toward the cover part (51).

摘要： A filter device has a filter element (3) received in a filter housing (1) and has a holding device (19) for detachably fixing the filter element in the filter housing (1). Corresponding threads (23, 33) form a screw connection between a housing cover (5) of the filter housing (1) and the filter element (3). A sealing device (29, 35) imparts a sealing action between the filter element (3) and the housing cover (5). The screw connection is formed by threads (23, 33) situated in the interior (22) of the filter element (3). The thread (33) assigned to the filter element (3) is situated on a connecting pipe piece (31) that, as a constituent part of an end cap (17) of the filter element (3), extends into the inner filter cavity (22) of the filter element (3). The thread (23) assigned to the housing cover (5) is situated on a receiving pipe piece (21), which can be screwed to the connecting pipe piece (31) of the filter element (3). The receiving pipe piece is formed by a separate component in the form of a pipe piece (21) attached to the housing cover (5).

摘要： A filtering apparatus includes a pot-type filter housing (10), a filter element (28) accommodated in the housing, a holding mechanism (38) disposed in the filter housing (10) to removably fix the filter element along its longitudinal axis, and a sealing device (60) that seals between a lid (20) of the filter housing (10) and the filter element (28). The holding mechanism (38) is provided with cooperating holding elements embodied on the interior face of the filter housing (10) as well as on the filter element (28). The filtering apparatus dispenses with the need for O-seals that are known in prior art and extend in a radial direction between the filter element and the filter head as a housing lid because the sealing device (60) encompasses at least one sealing edge (62) or sealing surface placed parallel to the longitudinal axis in a radial direction and seals under the effect of the pressure applied it by the holding mechanism (38). The invention further relates to a filter element that is to be used in such filtering apparatus.
