摘要： The invention relates to a method for forming a filter medium, which is suitable for filtering fluids, for a filter element, said method having at least the following steps: —applying at least one self-contained sealant (16, 28) onto a fluid-permeable media web (14) in a specifiable direction (26), —producing a solid composite at least between parts of the sealant (16, 28) and the media web (14), —pleating the composite, thereby forming individual filter folds, —producing a hollow body such that in order to —obtain at least one seal region on the media web (14), the respective sealant (16, 28) is arranged on the inner face of the hollow body, a seal is produced for each filter fold, and an end-face seal of the media web (14) is produced. An application medium is applied as the sealant (16, 28) onto the media web (14) in a strip-shaped manner along at least one longitudinal edge (51) of the media web (14), said sealant forming the respective seal region when cured.

摘要： A filter element (1), with a preferably multilayer structure of a filter medium (3), in pleated form has filter pleats (5, 7) of different pleat heights (h1, h2). The filter pleats (7) with a first pleat height (h1) oppose the filter pleats (5) lower second pleat height (h2). The filter element has a throughflow direction for fluid to be cleaned away from a dirty side to a clean side (R). The transitions arranged adjacent to the inner side all conclude along a fictitious circular cylinder (9), which penetrates the filter medium (3) coaxially to its longitudinal axis (LA).

摘要： 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).

摘要： A control device, in particular for hydraulically controlling components of mobile working machines, has a pressure supply connection (P) and a tank or return connection (T) in addition to two user connections (A, B). Control and/or regulating valves (10, 14, 16, 18) are connected between the individual connections (P, T, A, B). Two control lines (C, Z) can control at least one of the control and/or regulating valves. A modular-type functional block (24, 26) is connected to at least one of the control lines (C, Z).

摘要： A filter device with a filter body (1) has a filter bowl (3) and a filter head (5) formed by a removable locking piece of the filter bowl (3). The filter head (5) has a connection point (15) for an unfiltrate flow and a connection point (27) for discharging a filtrate flow. A filter element (7) containing filter material (11) is connected between the connection points (15, 27) and is disposed inside the filter bowl (3) for the filtration of the unfiltrate, specifically for particle contamination. A flow directing device (33) directs the unfiltrate flow to the surface sections of the filter material (11) of the filter element (7) to provide a filtering action when the device is in operation. The flow directing device is a molded component (33) that belongs to the filter head (5) and to which a fluid flow is applied.

摘要： A filter device for fluids with a fluid inlet (14) and a fluid outlet (24). A filter element (9) is enclosed by an end cap (21) on its lower end facing a bottom part (5) of the filter housing (1). The end cap has a passage (29) forming a fluid connection to the filter element inner filter cavity (17) and can be fixed to an element retainer (23) of the filter housing (1). The element retainer (23) includes a retaining piece (35) open towards the filter element (9) with a fluid channel (37) leading to a housing connection (24). The end cap (21) has a connecting piece (27) in the retaining piece (35). The retaining piece (35) forms an opening (43) connected to the fluid channel (37) leading to the element retainer (23). A sealing (45, 47) seals the opening from the open end of the retaining piece.

摘要： A filter element (20) includes individual components (2, 4, 8), such as a filter medium (8) as one component and further filter element components (2, 4), of which at least one component (4) is made of a material that is at least partially transparent to laser light and at least one further component (2), in the manner of a barrier layer, is made of a material that is at least partially opaque to laser light to perform a transmission welding method by laser light for connecting associable components to each other. At least some of the components of the filter element that are exposed to the laser light during the transmission welding method are at least partially electrically conductive.
