摘要： A method for operating a hydraulic system has at least one supply device, in particular a hydraulic pump (3) supplying different hydraulic consumers. A synchronizing device (33, 35) ensures that, if at least one hydraulic consumer is not supplied sufficiently, the deficit in volumetric flow for that consumer is compensated such that all the consumers compensate for the deficit equally.

摘要： A hydraulic valve device, especially in the form of at least one load sensing valve, includes a valve housing (10), a control slide (12) longitudinally movable in the housing and controlling a fluid connection arrangement (14). The fluid connection arrangement includes at least one control pressure line (PST) and at least one supply pressure line (Y). At least for a load sensing connection (LS), a pocket-type channel (18) is arranged between the valve housing (10) and the control slide (12), as well as for a control pressure line (PST) and a supply pressure line (Y). This arrangement enables the available ring channel of the load sensing message chain to be used on axial point of the control slide axle, reducing cost and space.

摘要： A filter device has a filter housing (1), at least one filter element (13) received in the filter housing (1) and an inner fluid space (71) limited by a filter medium (17) through which the fluid to be cleaned can flow. The filter medium separates the inner fluid space (71) from an exterior fluid space (11) located in the filter housing (1). The filter housing (1) has a fluid inlet (7) and a fluid outlet for cleaned fluid. A fluid guide device (9) is connected downstream to the fluid inlet (7) and can be optionally retrofitted to form a flow path between the fluid inlet (7) and the exterior fluid space (11) or between the fluid inlet (7) and the inner fluid space (71) disposed in the filter element (13).

摘要： A ventilation device for fluid-storing reservoirs includes a connecting part (1) attachable to the opening of the reservoir to form an air- and/or fluid-conducting connection between the inside of the reservoir and the surroundings. This connection is effectively sealed by a labyrinth-like seal of a system of seal passages (53, 59, 69, 73) from the penetration of media such as water and/or cleaning chemicals but is not sealed off from an exchange of air for ventilation. A filter element (61) is placed inside the connection. A portion of the seal passages (59, 69, 73) is formed on a ventilation chamber (41) releasably attachable to the connecting part (1) and having a seat (79) for the filter element provided as a filter leaf (61). The filter leaf (61) forms a partition between two successive seal passages (59 and 69) adjacently extending approximately parallel to one another.

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 lubricating device for gear trains (10), especially for wind power stations, includes at least two gear stages (16,18) that are disposed next to each other and are effectively interconnected, and a lubricant circuit (20) into which at least one filter unit (26) is mounted. To prevent stagnant resting zones for the lubricant from being created within the gear train housing including the gear stages, while ensuring that the entire lubricant that circulates in the gear stages is fed to the filter unit to be drawn off and filtered within predefined periods of time, the lubricant circulating inside the lubricant circuit (20) is discharged at one gear stage (18), is drawn off through the filter unit, and can then be fed to the other gear stage (16).

摘要： A device tests at least one quality parameter of a fluid in fluid apparatuses, e.g., working cylinders (10), hydraulic accumulators, valves, filter housings, pressure tubes, which at least temporarily accommodate a given fluid volume in at least one fluid chamber (12, 14). The fluid volume is stored in a storage unit (16) with the aid of a control mechanism (16) after being discharged from the fluid apparatus in order to be redirected from there into a measuring element (22, 24) to verify the respective quality parameter of the fluid. The inventive device makes it possible to specifically obtain a statement about the operability of the respective fluid apparatus within a very short period of time.

摘要： A filter element includes a filter cylinder whose outer side rests against a fluid-permeable supporting tube (15). The inside (3) of the filter cylinder can be flown through by the fluid to be filtered. The filter cylinder is formed by a filter mat web. The filter mat web has a series of folds (9) that rest against one another at least in areas. Both ends of the filter mat web are joined to one another at a junction (5) to form an annular body (1). The filter element includes a device that acts upon the junction (5) to prevent, in the area of the junction (5), a bulging of the folds (9) caused by the flow of the fluid.

摘要： A filter device includes a pot-shaped filter housing (1) that defines a longitudinal axis along which a filter element (13) can be inserted into and removed form the filter housing (1). A retaining device detachably retains the filter element (13) in the filter housing (1) and has first and second retaining elements on the inner side of the filter housing (1) and on the filter element (13) and interacting with one another. At least one set of the retaining elements has a shape coaxial to the longitudinal axis of the filter housing (1) and forms at least a part of a thread. When the filter element (13) is rotated about its longitudinal axis, it is locked in a form-fit.

摘要： A method produces a connection interface in a tubular filter element for filtering liquids, including a filter mat (10). The opposite ends (14) of the filter mat are interconnected in a connection position by a planar weld seam (28) provided with an embossed strip in the region of the free ends (14) of the filter mat. A region is provided between the embossed weld seam (30) and the beginning of the transition towards the tubular filter mats, in which a smooth weld seam (32) is applied without embossing in a flat strip along the ends (14) of the filter mat. This arrangement enables the ends of the filter mat to be welded together in a strong and long-lasting manner. The embossed weld seam is simultaneously unloaded of any stress by the smooth weld seam.
