Abstract: This filter element (1) comprises a filter medium (3) configured with an annular shape, having a central axis (X1) and forming inside a central channel (4) extending substantially axially, a first and a second end plates (5, 6), each plate covering one axial end of the filter medium (3) and being sealingly mounted on said axial end, the first end plate (5) having a central opening (7) substantially coaxial with the central axis (X1) and in fluid communication with the channel (4), and a central perforated rigid tube (9) that extends axially between the first and second end plates (5, 6) and having an inner perforated wall delimiting the central channel (4). The filter element (1) is designed to be placed in a filter housing (14) for forming a liquid filtering device (10), whereby a liquid to be filtered can flow along a liquid path through the filter medium (3) towards the channel (4) and out of the filter element (1) through the central opening (7). The central perforated rigid tube (9) comprises at least one guiding path (24), arranged inside the central perforated rigid tube (9), adapted to generate, by contact with a following member (204) of a rotatable central element (200) of the filter housing (14), at least a first, progressive rotational movement (A5) of the rotatable element (200) of the filter housing (14) when the filter element (1) is mounted in the filter housing (14) during a first translation movement (A1) along the central axis (X1). The at least one guiding path (24) comprises at least one portion of helical path (24A) for obtaining the first, progressive rotational movement (A5), and the helical path (24A) extends on less than half of the inner periphery of the central perforated rigid tube (9) in order to generate a rotation of the rotatable element (200) inferior to one half of a turn.

Abstract: A filter assembly includes a housing, a proximal end cap, and a nut plate. The housing defines a longitudinal axis and includes an inner surface surrounding the longitudinal axis. The proximal end cap is disposed within the housing and defines a central aperture. The nut plate is disposed within the housing and includes a flange portion and an outer wall. The flange portion is disposed within the central aperture. The outer wall includes a plurality of protrusions disposed about the longitudinal axis. At least one of the plurality of protrusions engages the inner surface to prevent rotation of the nut plate relative to the housing.

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 housing assembly for fluid filtration which may be attached to, and removed from, a filter base by a push-actuated release. The filter housing assembly has a top portion with an ingress port and egress port extending therefrom, and a protrusion extending from the filter housing longitudinally axial center. The ingress and egress port are formed in an hourglass shape. A filter key having a base with a groove for mating with said projection, at least one finger extending from said base, and an electronic circuit component housing attached thereto for receiving a printed circuit board, is connected to the filter housing top portion by mating said top portion protrusion with the filter key groove. Both of said ingress and egress port have at least one cavity for the passage of fluid therethrough, where each cavity is exposed in a direction facing away from the printed circuit board.

Abstract: A modular filtration platform having at least one manifold head and at least one respective filter cartridge assembly. Each manifold head is connected to one another to establish a water flow in a series or parallel manner. Each filter cartridge assembly is releasably secured from rotation relative to the manifold head by a locking mechanism. An aperture on the filter cartridge assembly annular collar mates with a protruding resilient extension on either the manifold head or support bracket. Alternatively, an aperture on the filter cartridge assembly annular collar and an aperture on the manifold head annular collar mate with a protruding member from a locking ring extending through both apertures. An integrated sensor package may be integrated with the system for true managed water visible/audible indications and Wi-Fi interface to facilitate virtually instantaneous response times for filtration needs.
