    Abstract: A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.

    Abstract: A hollow filter element of a fluid filter has a filter element-associated retention/carrier device of a retention/carrier system retaining the filter element in a first housing section of a filter housing during installation/removal in or from a second housing section by rotation and/or insertion movement. The filter element-associated retention/carrier device has a retention/carrier part extending radially and circumferentially and has through holes adjacent thereto extending circumferentially so as to enable a filter housing-associated retention/carrier part of the retention/carrier system to pass through axially. This retention/carrier part has a tensile face extending circumferentially and radially on a side facing away from an end face of the filter element facing the first housing section. This retention/carrier part has a rear side in circumferential direction. A space axially adjacent to the tensile face is connected on the rear side to a through hole for guiding through the filter housing-associated retention/carrier part.

    Abstract: A filter element includes a substantially cylindrical center tube having a first end, a second end opposite the first end, and a central longitudinal axis. The filter element also includes filter media extending circumferentially around and longitudinally along the center tube, and a plate connected to the center tube proximate the first end. The plate includes an orifice and a cap. The orifice includes a pilot feature configured to locate the filter element at a single circumferential position relative to the longitudinal axis, the cap extending from a top surface of the plate toward the second end and having an inner wall configured to mate with a drain plug. In such embodiments, the orifice and the cap are disposed radially inward of an inner circumference of the center tube, and at least one of the orifice and the cap extends circumferentially around an additional longitudinal axis spaced radially from the central longitudinal axis of the center tube.

    Abstract: A filter having a filter housing, an inlet for liquid to be filtered and an outlet for filtered liquid. An exchangeable filter insert separates an unfiltered side and a filtered side of the filter. A filter bypass valve has a valve seat and a valve body guided so as to be movable relative to the valve seat and preloaded in the closing direction. The valve seat is fixed to the filter. The valve body is guided in the filter so as to be fixed to the filter. A spring that preloads the valve body in the closing direction is guided in the filter so as to be fixed to the filter. The filter insert has a spring support that, in the state in which the insert is placed into the filter housing, supports and pre-stresses the spring at its end facing away from the valve body.

    Abstract: A filter and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock,” wherein cooperation of these keyed surfaces is required in order for the filter to be installed in the holder. Modification/adaptation of the keyed surfaces, by changing the location, number and length of the key protrusions and cooperating recesses during manufacture, allows various sets of mating filters and holders to be produced so that only mating/matching filters and holders may be connected together. The keyed protrusions are preferably located on an upper shoulder or on protruding flange(s) of the upper end of the filter. The cooperating recess structure inside the filter holder comprises axial recesses that allow axial insertion of the key protrusions, and hence the filter, into the holder and also a circumferential recesses portion that receives multiple key protrusions to retain the filter in the holder. This way, multiple key protrusions slide into and are retained in a single circumferential recess/slot, rather than each key protrusion being received in its own separate circumferential recess/slot.

    Abstract translation: 过滤器及其保持器各自具有带键表面，一个是突出的“键”，一个是凹入的“锁定”，其中需要这些键合表面的协作以使过滤器安装在保持器中。 通过在制造过程中改变键突起和配合凹槽的位置，数量和长度来改变键盘表面的修改/改编，允许制造各种配套的过滤器和保持器，使得仅配合/匹配过滤器和保持器可以连接在一起 。 键合的突起优选地位于过滤器的上端的上肩部或突出的凸缘上。 过滤器保持器内部的配合凹槽结构包括轴向凹槽，其允许将键突起部以及因此的过滤器轴向插入到保持器中，并且还包括容纳多个键突起以将过滤器保持在保持器中的周向凹部。 这样，多个键突起滑入并保持在单个周向凹槽/槽中，而不是每个键突起被容纳在其自己的独立的周向凹槽/槽中。
