摘要： An improved center-tube sealing grommet for use in a dual-flow filter assembly has annular lands which provide additional support to the filter elements located between the lands and a sealing flange. A fillet is incorporated into each annular land, extending from the grommet body to the annular land. Each fillet is positioned in a manner so as to facilitate the installation of the grommet into its respective filter element. Each annular land locks onto its respective filter element, providing a more rigid assembly that allows the filter element to be preassembled to the grommet prior to their installation into the filter housing. The improved center-tube sealing grommet provides increased stability which allows the axis of the filter elements to be maintained to the axis of the filter housing during the assembly of the dual-flow filter assembly, thereby reducing assembly defects.

摘要： According to the invention, several filter elements (13, 14) for purifying a liquid are connected with a connecting piece (21) to form a single constructional unit which is then arranged in a filter housing (12). One of the advantages of the inventive filter is that the filter elements (13, 14) can be connected before they are introduced into the filter housing (12). This makes the final assembly of the complete filter (11) considerably easier by reducing the number of parts. The connecting piece (21) can also be used to separate a flow of liquid into two sub-flows. The sub-flows can be filtered through different filter elements so that they differ in their degrees of purity.

摘要： The present invention provides a filter apparatus for removing impurities contained in a fluid that includes a housing (1), a full flow filter contained in the housing, the housing and the full flow filter (8) arranged such that the entirety of the fluid to be filtered by the filter apparatus passes through the full flow filter (8), a bypass filter (15), and a conduit (16) which contains a pressure reduction section (51). The full flow filter (8), bypass filter (15), and conduit (16) positioned within the housing (1) such that the bypass filter (15) is positioned downstream of the full flow filter (8) and the pressure reduction section (51) is arranged to create a pressure differential across the bypass filter (15) such that a predetermined portion of the fluid to be filtered by the filter apparatus passes through the bypass filter (15). The invention further provides a method of removing impurities contained in a fluid by filtration by introducing a fluid to a filtering apparatus including a full flow filter (8) and a bypass filter (15); filtering 100% of the fluid with the full flow filter (8); creating a pressure differential across the bypass filter (15) whereby a predetermined portion of the fluid filtered by the full flow filter is drawn through the bypass filter (15), thereby filtering the predetermined portion of the fluid a second time.

摘要： A fuel filter comprising a filter body (10) defining an internal chamber (15) within which a filter medium (16) is to be located, the filter body (10) being of multi-part construction, the parts (10 a , 10 b ) of the filter body (10) being non-removably, sealingly secured to one another. The filter body (10) is shaped to define an inlet port (11) and an outlet port (13) communicating with dirty and clean sides of the filter medium, respectively. The fuel filter may also include a second inlet port (12) for receiving fuel, a return port (14) arranged to permit the return flow of fuel from the filter to a low pressure fuel reservoir, and a temperature sensitive valve (22) operable to control whether fuel entering the filter body (10) through the second inlet port (12) is supplied to the dirty side of the filter medium (16) or supplied to the return port (14) for return to the fuel reservoir.

摘要： PCT No. PCT/GB95/02725 Sec. 371 Date Apr. 17, 1997 Sec. 102(e) Date Apr. 17, 1997 PCT Filed Nov. 23, 1995 PCT Pub. No. WO96/16716 PCT Pub. Date Jun. 6, 1996A full-flow fluid filter assembly is provided including a large pore size screen disposed in series with a relatively smaller pore size screen, together with a device responsive to obstruction of the smaller pore size screen to cause substantially all of the fluid flow to pass only through the large pore size screen. The arrangement is such that during use the fluid passes through both screens and, during bypassing of the smaller pore size screen, passes through at least the larger pore size screen. The device may be a one-way valve adapted to respond to increased back pressure developed across the small pore size screen. Preferably, the small pore size screen is provided with a shield or baffle adapted to minimize direct impingement of the fluid flow on the small pore size screen with the result of entrainment of debris from the small pore size screen during bypassing of this screen.

摘要： The invention relates to a filter provided with a bypass opening (14) to be used especially as an oil filter in hydraulic systems. The filter includes a casing-like filtering element (1) mounted on a support (3), whereby the stream to be filtered can be conducted into the space (11) defined by the element such that filtering takes place from this space through the filtering element envelope towards the outside of the space. The bypass opening (14) is produced by prestressing the filtering element (1) and the support against each other with a spring (5) such that, as the pressure in the filter exceeds the prestressing force, they will be dislodged relative to each other, leaving the opening concerned between the support and the filtering element (1). Essential features of the filter of the invention are that the filter is equipped with a frame (17) between the casing-like filtering element (1) and the support (3), that the frame and the support are prestressed against each other to leave a bypass opening (14) between them under the effect of pressure, and that the filtering element is removably attached to the prestressed frame. The frame (17) and the support (3) are kept continuously prestressed in the filter, while the cylindrical filtering element (1) attached to the frame, which does not affect prestressing, can be removed and replaced when needed.

摘要： An oil filter assembly for an internal combustion engine includes a body (31) which provides inflow and delivery passages and an attachable filter element container (45) which is attached to the body by a screw-thread at its open end to enclose a cylindrical pleated paper filter element (41) which is located by a perforated support tube (35) carried by the main body, the filter element (35) is sealed at one end against the body and is axially positioned by a spring (38) acting between the closed end of the container and a disc-like closure member (42) which thereby maintains engagement between one end of the filter element and the main body and sealing closure of the other end of the filter by the closure member sealing, the radial and axial compression of the filter element being limited by the support tube.
