Disclosed is a filter assembly capable of adjusting elimination of solid materials using a flow-variable bypass flow path. The filter assembly includes a filter portion (100) which includes a cover portion (110) formed on top to have a shape in which a bypass flow pipe (112) and a water discharge pipe (113) sequentially surrounds a perimeter of a vertically protruding original water inflow pipe (111) in a stepped structure and accommodates a filter body therein and a filter cartridge header (200) in which the cover portion (110) of the filter portion (100) is accommodated therebelow and which includes a bypass flow rate control unit (300) capable of adjusting an inflow amount of original water flowing into the bypass flow pipe (112).

The present disclosure relates to a filter system and a method for monitoring a vehicle condition using the same. The filter system according to an embodiment of the present disclosure includes a sensing apparatus installed at an exterior surface of a housing of a filter having a bypass valve, and configured to sense the condition of the filter, wherein the sensing apparatus is configured to include a hole sensor for sensing magnetic force caused by a location of a bypass valve lid, and a communication unit for transmitting measurement data of the hole sensor to outside.

A filtration system includes a filter housing having a cavity and a base, a drain defined in the base, a channel defined in the base and in fluid communication with the drain, and a filter cartridge having a longitudinal axis and being movable between an installed position within the cavity of the filter housing and an uninstalled position outside the cavity of the filter housing. The channel defines an outer diameter. The filter cartridge includes a bottom endplate defining an outer diameter that is greater than the outer diameter of the channel so that, in the installed position, the bottom endplate covers the channel and prevents fluid flow from the cavity to the drain, and a filter media extending axially outwardly from the bottom endplate.

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.

The present invention relates to a method for converting a full flow oil and/or fuel filter system into a bypass filter system comprising the use of a retro-fittable bypass filter configured to directly replace the pre-existing full flow filter, without the need for additional hoses or mounts etc. as in existing methods. Also described is a filter device for converting a full flow oil and/or fuel filter system into a bypass filter system comprising: an inlet for allowing fluid into the filter; a plurality of screens for filtering particles from the fluid; a cellulose element for filtering moisture from the fluid; an outlet for allowing fluid out of the filter; and a bypass for fluid to bypass the cellulose element and at least one screen and exit the filter, wherein the bypass filter is configured to directly replace the pre-existing full flow filter.

An exchangeable filter of a treatment device has a housing with a housing pot and a housing cover connected to the open side of the housing pot. The exchangeable filter is connectable to a connecting head of the treatment device with a bayonet-type connecting device. The connecting device has a housing connecting part on the housing interacting with a head connecting part of the connecting head for connecting the connecting device. The housing has an inlet for a fluid to be treated connectable to a supply conduit of the treatment head and an outlet for the treated fluid connectable to a discharge conduit of the treatment head. The housing pot has a rim at the open side of the housing pot. The rim radially outwardly surrounds the housing connecting part and axially projects past the housing connecting part in a direction away from the housing bottom.

A filter element may include a tubular member including a partition at least partially defining first and second chambers. The tubular member may further include at least one outlet aperture and at least one inlet aperture configured to provide flow communication exiting from the first chamber and flow communication into the second chamber, respectively. The filter element may be configured such that fluid passing through the filter element from an inlet port to an outlet port passes through the first chamber, a filter medium, and the second chamber. The filter element may also include an end cap having a return aperture configured to provide flow communication between fluid exiting from the first chamber and fluid entering the inlet port, wherein a portion of fluid exiting from the first chamber is returned to the inlet port for recirculation through the first chamber.

A fuel filter device for operation in a position under non-extreme conditions, when there is enough time for replacement of the clogged filter element, or in a reverse position in a fuel bypassing state for non-stop operation under extreme conditions, when there is no time for replacement of the clogged filter element. The device consists of cup-shaped members, which are interconnected through a threaded connection and form a cavity that contains a spring compressed between the bottom of an opening of one of the cup-shaped members and an abutment formed between two openings of another cup-shaped member. The compression force of the spring is applied to a seal ring placed into an annular groove formed in the abutment surface through a flange of the filter element. Another improved sealing feature is provided by a second seal ring, which seals the threaded connection, when the connection is tightened.

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.
