    摘要： A filter apparatus includes a filter housing having a filter head (3) and a filter bowl (7). The housing accommodates a filter element that separates a non-filtrate side (15) from a filtrate side (17). A differential pressure measurement device (59) indicates at least a blockage of the filter element during filtration operation and has a measurement piston (91) that is guided in a measurement housing (88) in a longitudinally displaceable manner. An end face (90) of that piston is subjected to the instantaneous pressure of the non-filtrate side (15). The opposite end face of the piston is subjected to the instantaneous pressure of the filtrate side (17). Each instantaneous pressure passes into the measurement housing (88) via at least one conduit (57, 61, 65, 89). At least a section (57, 61) of the conduit is arranged in an element cap (43) of the filter element.

    摘要： A filter device includes a filter element (3), through which a fluid to be purified can flow at a determinable fluid operating pressure, and which can be accommodated in a housing (1). The fluid pressure prevailing at the respective filter element (3) may exhibit pressure increases or pressure peaks, which are damaging to the filter element (3), and in particular to its filter material (9), and which can be reduced and/or smoothened by a compensation device acting directly on the filter element (3) and having a flexible compensation element (29) that enables the volume of the fluid chamber of the housing (1) to be increased in accordance with a pressure peak or pressure increase. The flexible compensation element (29) is arranged between the outer side of the filter material (9) of the filter element (3) and the adjacent inner wall of the housing (1).

    摘要： A filter device has a filter element (37) in a filter housing having a connection unit (29) forming a fluid connection to the filter element (37). The connection unit (29) feeds fluid to be purified to the dirty side (41) of the filter element (37) and is a component of the element receiver mounting the filter element (37) in the functioning position. The connection unit (29) is a component of the filter housing. The valve arrangement (61; 67, 69) is movable such that by removing the filter element (37) from the filter housing, the valve arrangement (61; 67, 69) closes and by insertion of the filter element (37) into the filter housing, the valve arrangement (61; 67, 69) opens.

    摘要： A filter device has a filter housing having two separable housing parts (1 and 11) that can receive at least one filter element (21). The housing parts can be connected to one another by a coupling device (7). The filter element (21), or an adapter that can be connected to it, forms a functionally essential component of the coupling device (7). Only when the filter element (21) has been placed in its functional position within at least one of the housing parts (1, 11), can the housing parts (1, 11) be connected to form the filter housing of a functional filter device.

    摘要： A filter device, in particular for fluids polluted with admixtures of water, such as diesel oil, includes a filter housing (1) having a fluid inlet (51), a fluid outlet and at least one filter element (9). During the filtering process, fluid can flow through the filter medium (11) of the filter element from the unfiltered side (13) to the filtered side (19) of the filter medium. The filtered side surrounds an inner filter cavity (17). On one side of the filter medium (11), a water-separating device (26) and a separating region (27) for separated water are present. The filter element (9) has a passage (43) that forms a fluid connection to the filter cavity (17) and at least one water opening (47) that is open toward the separating region (27). The filter element can be fixed to an element receptacle (29) of the filter housing (1) and can be connected to a water collecting chamber (33). An adapter part (49) is provided at least as part of a fluid-conducting system, in which fluid paths separated from each other are formed. A first fluid path (59, 67, 61) leads from a fluid connection (51) of the housing (1) via the passage (43) to the inner filter cavity (17) of the filter element (9). A second fluid path (69) connects the respective water opening (47) to the water collecting chamber (33).

    摘要： A filter device, in particular a return line suction filter, has at least one filter housing (3) receiving a filter element (17) defining a longitudinal axis. The filter element has an end cap with an enclosure at one filter element end enclosing an end edge of the filter material (39) and fixed to an element receptacle (5) connected to the filter housing (3) for fixing the location of the filter element (17) in its functional position. The element receptacle (5) and the associated end cap (21) of the filter element (17) have design irregularities (63, 65) adapted to each other at their parts (23, 47) engaging each other in the functional position of the filter element (17). The irregularities enable the engagement in a positional alignment to each other.
