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.

摘要： A device for branching a fluidic partial flow off a main flow by a hydraulic pump (10) includes individual main chambers (12, 14, 16, 18, 20) sealed from each other and divided into functional groups, and operates according to the displacement principle. The chambers enable fluid from at least one main flow inlet (22) to be transported from an inlet or suction side to an outlet or pressure side of the hydraulic pump (10) and then via at least one main flow outlet. At least one independent partial chamber (26) is provided for the transport of the partial flow in addition to the main chambers (12, 14, 16, 18, 20). The partial chamber forms part of the pressure side of the hydraulic pump (10) and is connected to an independent partial current outlet (42) separate from the main flow inlet (22) and the main flow outlet (24).

摘要： A valve arrangement has an adjustable control valve (10) including a control slide (12) for actuating at least one consumer connection (A, B) and an LS control line. The differential pressure of two actuating pressures (xa, xb) serves for the actuation of the control slide (12). Since the actuating pressures (xa, xb) also actuate a logic valve, which in turn influences an additional valve, and/or actuates a pressure compensator connected upstream to the control valve (10), the difference of the two actuating pressures (xa, xb) initially displaces the control slide of the control valve. The higher or the lower of the two actuating pressures (xa, xb) either actuate the further valve in the form of the additional valve, and/or influences the pressure compensator.

摘要： A hydraulic valve device includes a fluid connection arrangement (10) having different connections and a mobile control (18) for at least partially controlling connections of the fluid connection arrangement (10). The control (18) is provided with load reporting and load detecting connections (32, 38; 34, 36). According to the displacement position of the control (18), at least one part of the connections of the fluid connection arrangement (10) are interconnected in a fluid-guiding manner. The control can then be brought with precision into the required functional positions, with a favorable dynamic driving behavior.

摘要： A controlling device for hydraulic consumers (10, 12) has one controlling valve (18) for controlling a supply pipeline (TReg) for the hydraulic consumer (10, 12) and a tank return pipeline (TRO). Because the control valve (18) is connected to an additional supply pipeline (TR) and constructed as a priority valve, the supply pipeline (TReg) receives priority preference of a fluid supply system over the priority of the tank return pipeline (TRO). A sensor circuit is realized which checks whether, in accordance with the load situation at the hydraulic consumer (10, 12), there is any need at all for a supply flow.

摘要： A filter device has a cup-shaped filter housing (1), a filter element (13) in the housing and at least one end cap (21). A retaining device detachably fixes the filter element (13) along its longitudinal axis and has screwing elements (33, 41) interacting with each other and configured on the interior of the filter housing (1) and on the filter element (13). A sealing device (38) forms the seal between the filter element (13) and a housing terminating part (5) limiting the filter housing (1) at an end. The housing terminating part (5) forms an element receiving device having a fluid passage (43) concentric to the longitudinal axis (3). The fluid passage has inner screwing elements (41). A connecting piece (31) of the end cap (21) is able to be screwed into the passage using outer screwing elements (33). The sealing device has a sealing element (38) that is combined with the end cap (21) to form a cohesive component and that is accommodated in a seat (37) configured at the transition between the end cap (21) and the adjacent beginning of the thread turns (39) of the screwing elements (33) positioned at the connecting piece (31).
