    Abstract: 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.

    Abstract: The invention relates to an assembly for forming a seal between components (11, 33), which have sealing zones (37,51), said sealing zones facing each other in a functional position of the components. A sealing element (43, 57) is provided on the sealing zone (37, 51) of one component (11, 33) and a sealing surface (51) is provided on the sealing zone (37, 51) of the other component (11, 33) in order to form a radial seal, and the components (11, 33) can be brought into the functional position by a relative movement which is carried out in the axial direction, said sealing element (43, 57) sealingly interacting with the sealing surface (51) in said functional position. The invention is characterized in that the assembly has a third component (61) which is associated with an actuating part (62) that acts on the sealing element (43;57) in the functional position of the components (11, 33) so as to deform said element in order increase the sealing force.

    Abstract translation: 本发明涉及一种用于在组件（11,33）之间形成密封件的组件，其具有密封区域（37,51），所述密封区域在组件的功能位置彼此面对。 在一个部件（11,33）的密封区（37,51）上设有密封元件（43,47），并且在另一部件的密封区（37,51）上设置密封表面（51） 为了形成径向密封，可以通过在轴向上进行的相对运动使部件（11,33）进入功能位置，所述密封元件（43,57）密封相互作用 其中所述密封表面（51）处于所述功能位置。 本发明的特征在于，组件具有第三部件（61），其与在部件（11,33）的功能位置作用在密封元件（43; 57）上的致动部件（62）相关联，以便 以使所述元件变形以增加密封力。

    Abstract: A filter device has a filter housing (1) with a filter head (3), a filter pot (7) and a removable housing cover part (51) and has a filter element (13) separating a non-filtrate side (15) from a filtrate side (17) in the housing. A bypass valve device has a valve closure element (65) preloaded by a closing spring (69) into a closed position in which it bears against a valve seat part (74). If the filter element (13) is blocked, the closure element opens up a fluid path from the non-filtrate side (15) to the filtrate side (17), by passing the filter element (13). The valve closure element (65) and the closing spring (69) are on the cover part (51). The valve seat part (74) is on an element cap (43) of the filter element (13). The element cap has a receiving part (45) forming an enclosure for that end of the filter material (27) of the filter element (13) facing toward the cover part (51).
