Abstract:
A filter cartridge which is environmentally friendly in that it is made up of components which are all incinerateable. The ends of a filter element are sealed using potting compound and plastic endcaps. The upper endcap, which is closed, has a pressure relief aperture associated therewith to prevent bowing. In a plugged filter condition the high downward pressure introduced on the upper endcap is compensated by providing the cartridge with centering ribs which bottom on an associated ledge in the housing to provide a positive stop for the top endcap, preventing it from being driven down into and through the filter element. Rubber gaskets are associated with the respective endcaps, and are reliably secured to the endcaps by being snap fit into grooves molded into the plastic of the endcaps. The lower endcap utilizes a simple radial seal gasket which is both highly effective and also positioned to avoid structural crushing forces on the cartridge. A keying system prevents the installation of improper filters.
Abstract:
A filter system in which a housing and an environmentally friendly filter cartridge are coordinated to provide ease of change of the filter cartridge and reliable operation. The cartridge contains no metal parts and is readily incinerateable. The housing is provided with a number of “universality” features including a changeable bottom which allows the housing to operate as a fuel filter, a lubrication filter, or a hydraulic filter in different applications. The housing and cartridge are configured to provide support for the plastic elements of the cartridge to prevent crushing of the filter under normal and abnormal filter operating conditions. A key system associated with the cartridge and the housing provides assurance that the correct filter is installed for a particular application.
Abstract:
Provided is a container having a detachable lid that is suitable for use as a reusable oil filter and can improve the disassembling and assembling efficiency and minimize the weight. The container 1 suitable for use as an oil filter essentially consists of a casing 2, a set plate 3 closing the lower end of the casing 2 and a lock ring 4 that fastens the set plate 3 onto the casing 2. The casing 2 is provided with a radial outer flange formed around an open end of the main body thereof 22. The radial outer flange 23 is provided with three stop projections 25, three notches 26 and three biasing projections 27, the members of each threesome being arranged at a regular angular interval and each threesome being arranged at different angular phase positions from those of the other threesomes. The outer periphery of the set plate 3 is provided with three stop recesses 41, three notches 42 and three engagement rims 43, the members of each threesome being arranged at a regular angular interval and each threesome being arranged at different angular phase positions from those of the other threesomes. The outer periphery of the lock ring 4 is provided with three engagement lugs 54 that project inwardly at a regular angular interval.

Abstract:
An oil filter system includes an oil filter module and an adapter. The oil filter module includes a detent and an actuator. The adapter includes a protuberance and is configured to be secured to the engine. The oil filter module connects to the adapter when the detent secures to the protuberance as the oil filter module is urged into a connection position with the adapter. The oil filter module disconnects from the adapter when the actuator is actuated, thereby disengaging the detent from the protuberance.
Abstract:
A filtering device includes a container, a cover attached on top of the container having a space communicating with an inlet opening and a chamber of the container, and a filter screen received in the container for filtering the fluid from the inlet opening to the chamber of the container. The filter screen includes an upper peripheral flange having a peripheral wall or a peripheral flap for making an excellent seal between the container and the cover. The space of the cover includes a changing volume for decreasing the flowing speed of the fluid.
Abstract:
An environmentally friendly acid neutralizing filter cartridge is adapted to be mounted in a cartridge mounting body of an engine oil circuit for filtering particulates and neutralizing acid in oil. The filter cartridge comprises a support housing that comprises substantially no metal parts such that the filter cartridge can be readily incinerated. A full flow particulate filter and a bypass particulate filter are arranged in the support housing. A bed of acid neutralizing particles is contained in the support housing. The housing is configured such that a predetermined primary flow path is defined through the filter cartridge that passes through the full flow particulate filter and bypassing the bed of acid neutralizing particles; and a predetermined bypass path is defined through the filter cartridge that passes, in sequence, through the bed of acid neutralizing particles and the bypass particulate filter.
Abstract:
A liquid filter including a valve arranged in a supporting tube of a filter insert, in which the valve is fixed by a disk (60) which is oversized relative to a mounting opening (61), so that reliable sealing to the edges of the disk is facilitated. Use of the disk (60) simplifies the mounting of the valve.
Abstract:
A filter assembly for filtering water from an external source, the filter assembly including a manifold assembly mountable to an appliance and being in fluid communication with the external source and a cartridge assembly, the cartridge assembly being replaceably fluidly couplable to the manifold assembly, the filter assembly includes a first and a second fluid tube, the first fluid tube being fluidly couplable to the external source being an unfiltered fluid inlet, the second fluid tube being a filtered fluid outlet, the first and the second fluid tubes each having a barbed end for coupling to the manifold assembly. A tube retainer assembly is associated with each of the first and second fluid tubes, the tube retainer assemblies each having a port being fixedly couplable to the manifold assembly, the port having a retainer bore defined therein for receiving a tube barbed end therein, a retainer ring disposable on the tube, the retainer ring compressively engaging a barbed surface of the tube barbed end and being fixedly bondable to the port for forming a fluid tight seal between the fluid tube and the retainer assembly. A cartridge assembly and a method of disengaging the cartridge assembly from a manifold assembly are also included.
Abstract:
A fluid filter assembly includes a housing having a closed end and an open end; a filter element operably oriented in the housing; a baffle plate mounted to operably cover the housing open end; the baffle plate including a first axial face and an outer circumferential wall circumbscribing the first axial face; the outer circumferential wall being groove-free; the first axial face defining at least a first sealing groove; and a sealing gasket oriented in the first sealing groove; the sealing gasket forming a seal between the housing and the baffle plate. Methods of constructing, installing, and servicing includes fluids filters of the type described.
