A fuel filter system that does not require the periodic draining of a water sump. The system includes a fuel tank for storing fuel and a fuel filter fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side and a high pressure side. The high pressure side of the fuel pump is fluidly coupled to the fuel filter for pumping fuel to the fuel filter. A water emulsifier, such as an orifice, is fluidly coupled to the fuel filter to receive water and fuel from the fuel filter and form a water-fuel emulsion. The water-fuel emulsion is supplied to any point in the system on the suction side of the fuel pump, such that the water-fuel emulsion passes through the fuel pump and fuel filter.

Facial sealing system for a filter

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

The present invention relates to a filtering assembly () for filtering at least one fluid circulating in particular in an engine or a hydraulic device, comprising: a filter body (), which comprises a vessel () and a head (), the vessel () and the head () being provided to engage with one another in order to close the filter body (), in particular by screwing; a tube (), in particular a central tube, which is inside the filter body () and extends along a longitudinal axis (X); a removable filtration cartridge (,) which is accommodated in the filter body () and includes an upper end plate (), a lower end plate () and a filtration medium () which extends between the upper () and lower () end plates, the filtering medium () having a tubular opening () for surrounding the tube (), characterized in that the upper end plate () comprises first reversible rigid-connection means () and in that the vessel () comprises second reversible rigid-connection means () which are complementary to the first reversible rigid-connection means (), such as to enable the filtration cartridge () to stay in position in the vessel on the one hand, and in the filtering assembly () on the other hand, only by rigidly connecting the first and second reversible rigid-connection means ().

Filtering assembly comprising a filter cartridge

Assembly to be used to filter a fluid, containing a housing () which comprises a housing base () and a housing upper part () connected removably to the housing base (). An axial shaft () extends at least partially through the filter element () when the filter element () is contained inside the housing (). A lower bearing () is arranged between the axial shaft () and the housing base () and underneath the filter element () when a filter element () is contained inside the housing (). The housing () is able to contain a filter element () within it and the filter element () fits onto the axial shaft () in such a way that the axial shaft () is rotationally coupled to the filter element (). The filter assembly () has no bearing above the filter element ().
