A filter assembly has a housing with a housing inlet and a drain. A rotary vessel is rotatably mounted within the housing and has a rotary vessel inlet and a rotary vessel outlet. Fluid exiting the rotary vessel outlet exits the housing through the drain. A valve assembly moveable between a closed and an open configuration is provided. When closed, the valve assembly fluid-tightly seals rotary vessel inlet from housing inlet. When open, the rotary vessel inlet is in fluid communication with the housing inlet such that fluid flowing into the housing inlet passes into the rotary vessel inlet. The valve assembly is moveable from closed to open configuration when a pressure of fluid flowing into the housing inlet exceeds a threshold pressure. The filter assembly has a fluid passageway permitting air flow into the rotary vessel through the rotary vessel inlet when the valve assembly is closed.

A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.

A filter assembly comprises a filter housing defining an internal volume, a filter element positioned within the internal volume, and a gasket retainer. An outer edge of the gasket retainer is coupled to a top end of the filter housing, and an inner rim thereof forms a gasket retainer ledge. The filter assembly further comprises a retainer loop comprising a retainer loop main body. A plurality of retainer arms extend axially from the retainer loop main body towards the gasket retainer. Each of the plurality of retainer arms comprise a retainer arm ledge extending radially towards the retainer loop main body and snap-fit to the gasket retainer ledge. A retainer loop sidewall extends from the main body away from the gasket retainer. An outer surface of the retainer loop sidewall defines a curvature. A sealing member is removably positioned around the outer surface of the retainer loop sidewall.

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.

Various example embodiments relate to a filtration system and methods for the installation and use of such a filtration system. According to a set of embodiments, the filtration system comprises a housing that defines a central compartment therein. The filtration system further comprises a filter cartridge positioned within the central compartment of the housing. The filter cartridge comprises a filter media and an identification element. The filtration system further comprises a sensor. The sensor is structured to sense the identification element of the filter cartridge. The filtration system further comprises a filter blocking mechanism communicably coupled to the sensor. The filter blocking mechanism is structured prevent installation of the filter cartridge into the housing unless filter cartridge information of the identification element sensed by the sensor is identified as corresponding to an authorized filter cartridge.

A filter element of a filter for liquid has a filter medium surrounding an element interior circumferentially continuously relative to a virtual axis. An end body is connected to an axial end face of the filter element and has a filter element drainage opening surrounding the virtual axis and connected to the element interior. The end body has a filter element sealing surface or filter element seal surface of a filter element sealing device which surrounds the filter element drainage opening circumferentially continuously and closes the filter element drainage opening when the filter element is mounted in the filter. A seal of the filter element sealing device that is circumferentially continuous relative to the virtual axis is fastened at the filter element. A discharge closure element closes the discharge opening of the filter housing of the filter and has a sealing surface that close the filter element drainage opening.

A filter element arranged exchangeably in a filter housing of a filter has a filter medium delimiting an element interior. An end body arranged at the filter medium has a fastening region surrounding the interior opening that communicates with the element interior. An insertion adapter for connecting the filter element to a fluid connector of the filter housing has an insertion sleeve insertable axially into the fastening region of the end body. The inward side of the fastening region is provided with a material that is initially flexible during manufacture of the filter element and hardens later on. The insertion sleeve has a holding element radially outwardly arranged at the circumference. With inserted insertion sleeve, the holding element is arranged in the fastening region. The initially flexible material of the fastening region flows behind the holding element and forms a form fit connection with the holding element when hardened.

According to one aspect of the present disclosure, a filter assembly includes a filter housing including a housing inlet and a housing outlet, and a filtering section located downstream of the housing inlet and upstream of the housing outlet. The filtering section includes a first filtering portion, a second filtering portion, a wall longitudinally separating the first filtering portion and the second filtering portion, a filtering outlet, and a valve located in the filtering outlet. The valve includes a closed condition and an open condition, and wherein, in the valve closed condition the valve blocks flow from the second filtering portion to the housing outlet.

An oil filter assembly for an engine of an outboard motor includes a base having a high-pressure inlet port, a filter-mounting interface for receiving a filter, and a drain-back port for receiving a drain-back insert of the filter. The base includes an engine-mounting interface for mounting the base to the engine, which includes a high-pressure outlet port and a low-pressure outlet port providing oil to the engine. The base provides fluid communication between the high-pressure inlet port and an inlet side of the filter and between an outlet side of the filter and the high-pressure outlet port when the filter is installed and the drain-back insert is within the drain-back port. The base provides fluid communication between the drain-back port and the low-pressure outlet port when the drain-back insert is not within the drain-back port. A clean oil fill passageway is in fluid communication with the low-pressure outlet port.

A device for passing lubricant out of a lubricant collecting container to a lubricant pump, in particular for an oil circuit of an internal combustion engine. The device including a lubricant intake pipe and a sedimentation container, which is connected fluidically to the lubricant intake pipe.
