The present invention relates to a filtering assembly for filtering at least one fluid flowing in particular in a hydraulic motor or device, comprising: &#x2014;a filter body which comprises a vessel and a cover which are configured to engage with one another in order to enable the filter body to close, &#x2014;a tube, in particular a central tube, inside the filter body extending along a longitudinal axis (X), &#x2014;a removable filter cartridge which is housed in the filter body and includes an upper end plate, a lower end plate and a filter medium which extends between the upper end plate and the lower end plate, the filter cartridge having a tubular opening for surrounding the tube, characterized in that the cover has a circular rib which is formed such as to project into an inner space of the filter body, and in that the upper end plate has a circular edge which is designed to sealingly engage radially and inwardly with said circular rib of the cover.

Filtering assembly comprising a filter cartridge

A Spin-on filter assembly that can be used with both suction-side and pressure-side filtration systems is described. The filter assembly screws onto a filter mounting head. The filter mounting head is part of a filtration system that provides fluid to be filtered to the filter assembly. The filter assembly filters the fluid to be filtered through a filter media contained within the filter assembly and provides the filtered fluid back to the filter mounting head. The filter assembly includes an upper seal that seals the clean side of the filter media from the dirty side of the filter media when the filter assembly is connected to the filter mounting head in an installed position. The upper seal includes a sealing ridge that has an elongated shape and is flexible such that the filter assembly can be used on both pressure-side and suction side applications in filtration systems.

Spin-on filter for suction-side and pressure-side applications in filtration systems

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 spin-on filter that eliminates the use of a nut plate and reduces the number of separate components. Instead, the spin-on filter utilizes the end plate of the filtercartridge to perform a number of functions, including closing the open end of the filter shell, sealing between the dirty and clean fluid sides, sealing between the filter and the mounting head to prevent leakage outside the filter to environment, attaching the filter cartridge to the shell, and sealing the end of the filter media.
