Abstract:
A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base. Keyed arrangements may occur between a filter element and a filter housing, a filter and a filter base, and a filter base and a filter housing. A locking arrangement may be provided to prevent undesired loosening of a filter relative to a filter base. The filter base may include a torsion lock insert that engages lock detents of a filter to prevent the undesired loosening. An adaptor may be provided to provide the lock detents that interact with a torsion lock insert.
Abstract:
A liquid filter arrangement is provided, as well as methods of assembly and use. Advantageous features, relating to a preferred filter cartridge and a preferred slide arrangement, are provided.
Abstract:
A fluid filter includes a base plate, a canister, and filtering media contained in the canister for filtering fluid from an inlet port to an outlet port. Notches are formed into an outer periphery of the base plate. An annular bead of the canister side wall is partially formed into the notches to provide a torque locking mechanism between the base plate and the canister. The terminating lip portion of the canister is wrapped around the outer face of the base plate and formed into an annular trough to directly secure the base plate to the canister. The annular trough includes a diverging outer wall that provides a narrow contact interface between the terminating lip portion and the retention corner of the base plate to thereby reduce moment loads induced therebetween as a result of high fluid pressures in the filter.
Abstract:
A filter system for a fluid having a cup-shaped housing releasably connected to a connecting head and a filter element arranged in the housing, in which the releasable connection is formed by at least one connecting element formed on the connecting head which engages a connecting element formed by a part of the filter element in combination with a part of the cup-shaped housing such that the connection between the housing and the receiving head can only be produced if a proper filter element is installed in the housing.
Abstract:
The present invention relates to a retaining device for retaining at least one external functional apparatus comprising at least two tube ports on a treatment apparatus, wherein the retaining device comprises at least two stops which restrict a rotational movement of the external functional apparatus inside the retaining device. It further relates to an external functional apparatus as well as a treatment apparatus.
Abstract:
A filter assembly for filtering water from an external source, the filter assembly having a manifold assembly and a filter cartridge. The filter cartridge includes a cartridge engagement means while the manifold includes a manifold engagement means. The cartridge engagement means and manifold engagement means cooperatively interfacing for removable attachment of the filter cartridge to the manifold assembly. The cartridge engagement means and manifold engagement means oriented in a retaining relation during removal of the cartridge filter from the manifold assembly such that any entrained pressure within the cartridge filter is vented while the cartridge engagement means and manifold engagement means are in the retaining relation.
Abstract:
A fuel filter assembly includes a header and a can-shaped housing removeably attached to the header. The can-shaped housing has an upper rim portion provided with a plurality of notches therein. A filter unit has an upper end cap provided with a plurality of tabs extending from the periphery and positioned within the notches of the housing. The spacing of the notches about the axis of the housing must be the same as the spacing of the tabs about the axis of the filter unit to permit the filter unit and housing to be properly assembled, thereby preventing the use of an incorrect filter unit within the housing. Additionally, the header has a plurality of key slots that receive the tabs on the filter unit. The spacing of the key slots and tabs must be the same to permit the housing and received filter unit to be properly connected to the header.
Abstract:
A water treatment apparatus includes a frame and a plurality of connecting accessories, manifolds and filter cartridges. Each of the connecting accessories includes a seat ring fixed on the frame and a communicating pipe coaxially received in the seat ring. The seat rings together with the communicating pipes are spaced at a distance from one another. Each of the manifolds is suspended between adjacent two of the connecting accessories and has inlet and outlet ports at opposite ends. The inlet and outlet ports of each of the manifolds are rotatably and coaxially received in adjacent the seat rings respectively with their exterior walls in contact with inner walls of adjacent the seat rings and their interior walls in contact with outer walls of adjacent the communicating pipes. Additionally, the filter cartridges are detachably joined to the manifolds respectively.

Abstract:
An oil filter arrangement (10) comprises a housing, which has a receiving chamber (16) for a filter element (18) which can be cross-flowed in a radial manner by oil and which can be inserted into the housing, a support tube (42) which supports the filter element when it is inserted and a cover (14) which can be screwed to the housing (12) via a thread (15). The cover comprises engaging ribs (44) which are used to rotate the filter element (18) when screwing and/or unscrewing the cover (14) to the housing and/or from the housing.
