The system also includes a return flow line (20) for a return flow of fuel from the fuel injection apparatus (16) to the low pressure reservoir (10), and a filter arrangement (32) including a primary filter (14) arranged within the primary supply line (11) for filtering contaminants in the fuel flow through the primary supply line (11) and a secondary filter (30) arranged within the return flow line (20) for filtering contaminants from the flow through the return flow line (20).
Abstract:
A recharge and filter assembly (10) includes a housing (12) with a removable recharge and filter cartridge (142). The housing (12) includes a canister (13) with a removable cover (14) allowing access to the cartridge (42). The cartridge (42) includes a filter element (43) comprising a ring of media (45) and upper and lower end caps (50, 52). The upper end cap (50) carries a peripheral seal (86) which provides a fluid-tight seal with the housing canister (13). An annular channel (97) is provided between an annular portion (66) of the upper end cap (50) and the seal (86). An annular support member (100) from the cover (12) is received in the annular channel (97) to support the upper end cap (50). Latching fingers (74) on the upper end cap (50) and a mating ring (78) on the cover (12) removably couple the cartridge (42) to the cover (12). The cartridge (42) further includes a recharge canister (44) supported by tabs (120, 130) on the upper and lower end caps (50, 52). Fluid is recharged by the recharge canister (44), while particulates and other contaminants are removed by the filter media (45).

The system includes a controller (16) for controlling the operation of the peripheral treatment for the introduction of coagulants, flocculants and polymers to treat or condition a slurry introduced into the filter (32) and the control of additional peripheral equipment for treatment of the slurry with liquid clearing or cake forming gas, steam, or drying or conditioning gas within the filter chamber (40) for the production of both filtrate and filter cake from the filter (32) to a form desired.
Abstract:
The invention relates to a hydraulic circuit for filtering a fluid, comprising a fluid accumulator (10), a fluid pump (17), a user (14) a filter element (23) and a controller (24). A heated fluid can at least partly be fed to the filter element (23). Said hydraulic circuit may be applied in fluid systems whereby a fluid, such as for example water, oil or fuel is filtered and there is at least partly a return of fluid to the fluid accumulator (10). According to the invention, fluid is pumped in said hydraulic circuit by means of the fluid pump (17) from the fluid accumulator (10) in fluid lines (11, 13, 15, 16), purified by a filter element (23) and supplied to a user (14). The fluid not required by the user (14) is returned by means of a fluid return line (15) to the controller (24) which returns the fluid to either the filter element (23), or the fluid accumulator (10), according to the fluid temperature. Furthermore, the controller (24) and the filter element (23) are arranged in a common housing (18), provided with a raw fluid inlet (19), a clean fluid outlet (20), a fluid return (12) and a fluid outlet (22). By means of said connectors fixed to the housing (19, 21, 22) a rapid and simple assembly of the fluid circuit is possible.

Die Erfindung betrifft einen Kraftstofffilter (1) mit einem Filterelement und Anschlüssen (4, 8) für die Kraftstoffzufuhr und den Kraftstoffauslass. Um eine kompaktere Bauweise zu ermöglichen, wird ein Kraftstofffilter (1) mit einem flach ausgebildeten, blockartigen Filterelement vorgeschlagen.
Abstract:
The present invention is directed to a filter module that may incorporate sensors to measure various characteristics of fluid flow and filtration. The sensors may be MEMS and may measure the temperature, flow rate, pressure, etc. of the fluid. One or more MEMS sensors may be included in a sensor package which, in turn, may be included in a sensor component. The latter, which may also include a processor, conductor pins, etc. for data communication, may be coupled to a sensor port in such a way as to allow contact between the sensor(s) and the fluid. Sensor measurements may be used to determine the occurence of harmful events, such as cavitation or particle breakthrough, or to predict the remaining service life of a filter element.
Abstract:
A monitoring system (10) is disclosed for monitoring the condition of a filter (16) filtering a gas or liquid. Using various sensors, the permeability of the filter is monitored on a continuous basis. A significant increase in permeability, decrease in permeability or rate of change of permeability can lead to an indication of filter failure, such as rupture, leakage, loading and unloading. The system can be monitored by a computer and monitored from a remote location through phone lines and Internet computer systems.
Abstract:
Filtering apparatus includes two or more passages (2) acting in parallel, each having an extended filter (12) which passes through inlet and outlet ports (48, 49), preferably sealed by solidified plugs of the flowable substance such as a polymer being filtered. The flow of such substance to one passage can be terminated so as to permit filter advance under conditions of zero pressure drop, whilst flow through the other passage continues. Filter advance can be assisted by extrusion of a sealing plug in the outlet port under the pressure of such substance from the other passage which is still filtering. In an additional or alternative mode, flow into a passage is terminated and a secondary outlet (20, 21) in that passage is opened. This creates a counterflow under the pressure of substance from the other passage, which cleans the filter. The secondary outlet can be sealed by a plug which is extruded during counterflow. An alternative valve for the secondary outlet, which can also be used in a diverter valve for controlling the input of substance to the two passages, has a side passage (26) in which is formed a plug of solidified substance, and means (27) for pushing the plug into the flow substance.
