Abstract: A fuel filter cartridge assembly employs a two piece housing to house a replaceable filter unit. The filter cartridge assembly incorporates a key system to ensure compatibility of a replacement filter unit for a given cartridge assembly. Keys formed on the filter unit cooperate with keyways formed in the housing to ensure that only filter units having key structures may be used. Each key may have a different angular position, angular dimension and radial projection. By varying the dimensions of the keys and/or the positions and/or the number of keys, a composite compatibility matrix comprising an infinite number of configuration sets are available to differentiate between filter units having differing flow capacities, filter media, disposal options or other characteristics.

Abstract: Embodiments of a fluid filtering assembly are shown and described, each embodiment including a valve head that routes fluid to and from a filter cartridge and that includes a valve system that automatically opens and closes when the filter cartridge is inserted and removed, respectively. The valve system preferably includes a generally-cylindrical piston with a hollow interior space, which receives a stem member. The stem member has a bottom-end seat or sealing member and has a central body shape that allows fluid to flow up through the piston interior space, either through or up around the stem member. Upon removal of the filter cartridge, the piston is biased to move down into an "off" position, to close both the inlet and outlet fluid passages. In this "off" position, the piston exterior surface blocks off radial fluid inlets and the piston interior surface seals with the stem bottom end seat to prevent fluid backflow out of the piston interior space. The filter cartridge preferably includes a neck with a centrally-located, vertical fluid outlet hole surrounded by a ring of vertical fluid inlet holes near the outer perimeter edge of the neck.

Abstract translation: 流体过滤组件的实施例被示出和描述，每个实施例包括将流体输送到过滤器滤芯和从过滤器滤芯传送流体的阀头，并且包括分别在过滤器滤芯被插入和拆卸时自动打开和关闭的阀门系统。 阀系统优选地包括具有中空内部空间的大致圆柱形的活塞，其容纳杆构件。 杆构件具有底端座或密封构件，并且具有允许流体通过活塞内部空间向上流动的中心体形状，或者通过杆构件的上方或上方向上流动。 在移除过滤器滤芯时，活塞被偏压以向下移动到“关闭”位置，以关闭入口和出口流体通道。 在该“关闭”位置，活塞外表面阻挡径向流体入口，并且活塞内表面与阀杆底端座密封，以防止流体从活塞内部空间流出。 滤筒优选地包括具有中心位置的垂直流体出口孔的颈部，所述中心位置的垂直流体出口孔被靠近颈部的外周边缘的垂直流体入口孔环围绕。

Abstract: The fixing apparatus for fixing a fuel filter in the present invention comprises a ring portion for fixing fuel filter body securely by utilizing contraction force of resin. The fixing apparatus is made of resin softened by heat. The resin fixing apparatus has ring portion for accommodating and fixing a fuel filter. The inside shape of the ring portion is formed similar and somewhat smaller than the outer cylindrical shape of the fuel filter body. When the ring portion is heated and the resin and resin become flexible, the fuel filter is allowed to be press fitted into the ring portion.

Abstract: A high-strength spin-on filter (10) of improved fatigue strength comprises a cylindrical housing (12), a unitary cover (28) and an internal filter element assembly (18). The open end of the housing (12) is folded inwardly over the periphery of the cover (28) and into deformable engagement with radial projections (54) thereon to secure the cover and housing against both relative rotation and separation without stress concentrations that would otherwise decrease fatigue life of the filter (10) in high-pressure pulsatile hydraulic systems.

Abstract: A retention mechanism for releasably securing a receptacle to another component includes a ratchet lever pivotally mounted about a screw, a torsion spring having a first end attached to a first end of the lever and being biased to pivot the lever about the screw axis to a first, locked position. A second end of the lever engages, in use, with teeth provided on the receptacle to secure the receptacle against rotation relative to the other component. The mechanism has a compression spring arranged to bias the lever in an axial position such that, in the first, locked position, the second end of the lever engages the teeth. The first end of the lever is configured to receive pressure from a user against the force of the torsion spring to pivot the lever about the axis such that the second end of the lever disengages from the teeth.

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 thread locking mechanism may be include in a threaded portion of a removable part to enable the removable part to be securely locked to an assembly such that the removable part does not turn when another part is being attached or removed. The thread locking mechanism may also be un-locked when it is desirable for the removable part to turn and be removed from, or further secured to, the assembly. In some examples the removable part may be an oil filter adapter, the assembly may include an engine, and the other part may be an oil filter.

Abstract: A filter element has a first follower element with a first traction surface and a second follower element with a second traction surface provided for interacting with first and second mating surfaces of the filter housing, respectively. The first and second traction surfaces interact with the first and second mating surfaces to pull out the filter element from the filter housing. The first and second traction surfaces are spaced apart from each other along a longitudinal axis of the filter element and project radially into the interior of the filter element. At least one of the first and second follower elements has a stop surface adjoining circumferentially the respective traction surface. In a position of use, the stop surface interacts with a counter stop surface of the filter housing to form an at least unidirectional rotational degree of freedom blocking about the longitudinal axis relative to the filter housing.

Abstract: A filter cartridge comprises a filter housing having a filter element disposed therewithin that comprises a filter media, and an end cap coupled to a top end of the filter media. The top end is positionable proximate to a filter head. A filter element outlet conduit extends from an inner rim of the end cap towards the filter head and is extendable into a filter head outlet. An end cap ledge extends radially outwards from an outer periphery of the end cap. A first sealing member is disposed at least partially on the end cap ledge and forms an axial seal with the filter head, and a second sealing member is disposed around the filter element outlet conduit on a radially outward surface thereof, and forms a radial seal with a radially inward surface of the filter head outlet conduit when the filter head is coupled to the filter cartridge.
