A water filtration system that includes a filter manifold having a rotatable cover is provided. A filter cartridge is provided that includes a sump having a filter head integrally secured to a first end and cap releasably secured to a second end. A locking mechanism extending from the cover locks into the filter manifold to position the cartridge in an “in-use” state. The filter cartridge further includes two offset cylindrical inlet and outlet members protruding from the filter head that are designed to engage corresponding inlet and outlets of the filter manifold through a horizontal engagement mechanism. A check valve is positioned within the filter manifold adjacent the inlet of the filter cartridge to control fluid flow through the water filtration system. The filter cartridge head includes fins upwardly extending therefrom that are configured to engage corresponding slots formed in a plurality of corrugated channels of the filter manifold.

Disclosed is a disposable filter capsule apparatus that incorporates integral quick connect components and check valves to facilitate assembly to, and dis-assembly from, larger assemblies and apparatus. The quick connect elements and valves are configured to eliminate the need for auxiliary sealing elements, e.g., o-rings and valve springs so as to prevent unwanted reactions with fluids and/or gases flowing through the capsules, and to further prevent the disposal of expensive re-usable elements in the disposable capsules.

A filtration system comprises a housing and a shell housing removably coupled to the housing. A valve comprise a valve housing and a plunger. The plunger comprises a seal member structured to seal an opening in the valve housing. The plunger is axially movable between a closed position, in which the seal member seals the opening, and an open position, in which the seal member does not seal the opening, thereby permitting fluid to flow through the valve housing. A filter element comprises filter media and an endcap. The endcap comprises an alignment tab configured to rotationally secure the filter element with respect to the shell housing when the shell housing is received in the housing. The endcap comprise a valve interaction projection structured to transfer rotation of the filter element and the shell housing to the plunger during installation of the filter element.

A filter system for liquid has a filter head with drainage channel and stop element. A filter cartridge is mounted by screw-in movement at the filter head and has a support ring rotatably fastened to its housing part. The support ring has an eccentric closure element and a first positioning element guided toward the stop element by the screw-in movement to position the support ring at the filter head in a rotational position for axially aligning closure element and drainage channel. The closure element is transferred axially into a sealing seat at the filter head to close the drainage channel when screwing on the filter cartridge. The support ring has a second positioning element holding the support ring in a rotationally fixed position at the filter head when unscrewing the filter cartridge so that the closure element is moved out of the sealing seat only in an axial direction.

An apparatus and a method are provided for a high capacity oil filter configured to remove contaminants from engine oil flowing within an internal combustion engine. The oil filter comprises a hollow canister having a length and a diameter suitable for housing a large filtration medium. A base gasket forms a fluid-tight seal between the oil filter and the engine. A base plate circulates oil from the engine through the oil filter. An anti-drainback valve prevents oil from draining out of the filter and passages within the engine when the engine is not operating. A key aspect of the present disclosure is that the relatively large dimensions and the configuration of the filtration media provide a large surface area for entrapping contaminants flowing with the engine oil.

A removable filter cartridge includes a filter housing containing a filter, a sealing valve coupled to an open end of the filter housing and configured to removably couple the removable filter cartridge to a filter head. The sealing valve has an open position and a closed position that seals the filter housing, and is configured to maintain a seal of the filter housing while uncoupled from the filter head. A sealing valve includes a first end to be removably coupled to a filter head and a second end to be coupled to a filter housing to form a removable filter cartridge. A method of retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the filter housing to form a removable filter cartridge, and removably coupling the removable filter cartridge to the filter head.

A water purifier includes a filter head, a flow channel control module, and a filter element. The flow channel control module includes a waterway board and a flow manifold. The waterway board is provided with a water flow channel. The flow manifold is provided with a first passage and a second passage. When the flow manifold is driven by the filter element and rotated relative to the waterway board to a first position where the first passage is connected to the water flow channel, the flow channel control module is switched to a first flow channel waterway mode (or filter mode). When the flow manifold is driven by the filter element and rotated to a second position where the second passage is connected to the water flow channel, the flow channel control module is switched to a second flow channel waterway mode (or replacement mode).

A water-treatment device (100) comprising a head (2) and a water-treatment cartridge (1) configured for being arranged in the head (20) of the water-treatment device (100), which the device (100) is configured for treating water in the water-treatment cartridge (1). The water-treatment device (100) is characterized in that the device (100) comprises a first element (9A, 9B) of the orienting-ejecting means, arranged on the water-treatment cartridge (1), and a second element (26A, 26B) of the orienting-ejecting means, arranged on the head (20) of the water-treatment device (100), wherein, when the first element (9A, 9B) and the second element (26A, 26B) of the orienting-ejecting means are engaged, the position of the water-treatment cartridge (1) in the head (20) of the water-treatment device (100) is stabilized, when the cartridge (1) is mounted in the head (20) of the device (100), and there is provided ejection of the water-treatment cartridge (1) from the head (20) of the water-treatment device (100) during removal of the cartridge (1) from the device (100) by rotating said cartridge (1) around its longitudinal axis relative to the head (20) of the water-treatment device (100).

A filtration system comprises a housing and a shell housing removably coupled to the housing. A valve comprise a valve housing and a plunger. The plunger comprises a seal member structured to seal an opening in the valve housing. The plunger is axially movable between a closed position, in which the seal member seals the opening, and an open position, in which the seal member does not seal the opening, thereby permitting fluid to flow through the valve housing. A filter element comprises filter media and an endcap. The endcap comprises an alignment tab configured to rotationally secure the filter element with respect to the shell housing when the shell housing is received in the housing. The endcap comprise a valve interaction projection structured to transfer rotation of the filter element and the shell housing to the plunger during installation of the filter element.

An exchangeable filter system is provided with an exchangeable filter module that has at least one fluid inlet, at least one fluid outlet, and a fluid path connecting the at least one fluid inlet and the at least one fluid outlet with each other. The exchangeable filter module is provided with at least one filter element for filtering a fluid. A flange element and a counter flange element are provided. The flange element is provided to releasably engage the exchangeable filter module and to releasably engage the counter flange element. A valve device is arranged in the flange element. The valve device blocks the fluid path when the flange element is in engagement with the exchangeable filter module and is disengaged from the counter flange element. An internal combustion engine is provided with such an exchangeable filter system to filter fuel, lubricant or urea.
