摘要: A filtering device includes a cylindrical screen (2) and a backwash tube (3) provided in the cylindrical screen and rotatable about its axis. The backwash tube (3) has an inlet (3c) for introducing filtered liquid in one end and an opening (3d) for discharging the filtered liquid and introducing backwash water in the other end and has backwash water injection holes (13) formed in the axial direction at a predetermined interval. A check valve (14) is provided on the side of the opening (3d) for discharging the filtered liquid and introducing the backwash water in the vicinity of the inlet (3c) for the filtered liquid for allowing flowing of the filtered liquid from the inlet (3c) to the backwash tube (3) and prohibiting flowing of the backwash water from inside of the backwash tube to the inlet. Backwash tube rotation means which may be made of a blade (15) or offset backwash water injection holes is provided for rotating the backwash tube (3) about its axis.

摘要: The invention concerns a filter device with a bypass valve (20) which, releases a fluid-conveying path to an outlet when a filter element (14) becomes clogged and comprises a closure part (22) on which at least one closure spring (24) acts. According to the invention, in order to adjust the spring pretension and hence the opening force for the closure part (22), an adjusting device (28) is provided for adjusting the opening force of the respective closure spring (24). As a result, a filter device is provided which can be economically adapted without any structural modifications to very different applications in a predetermiend pressure range.

摘要: Es wird ein Flüssigkeitsfilter zum Reinigen von Kraftstoffen vorgeschlagen, das als Gehäusefilter (10) mit lösbarem Gehäuseteil (12) ausgebildet ist und an dessen Deckelteil (15) ein Filtereinsatz (19) axial aufgesteckt ist. Der Filtereinsatz (19) hat ein radial durchströmtes Hauptfilterelement (21) und ein dazu konzentrisch in letzterem angeordnetes Hilfsfilterelement (22), das erst bei verschmutztem Hauptfilterelement (21) und dabei auftretender Druckdifferenz über ein in Serie zum Hilfsfilterelement (21) geschaltetes Druckdifferenzventil (45) zur Standzeiterhöhung aktivierbar ist. Das Druckdifferenzventil (45) ist unmittelbar im Deckelteil (15) angeordnet, wodurch sich eine einfache, kompakte und kostengünstige Bauweise ergibt, bei welcher der Filtereinsatz leicht austauschbar ist.

摘要: A filter unit comprises a housing (10;30) containing a filter element (11;34). The housing (10;30) includes an inlet (12;39) for fluid and an inlet passage (14;51) which passes fluid to the filter element (11;34). An outlet passage (15;47) conveys filtered fluid from the element (11;34) to an outlet (13;40) to the housing (10;30). The inlet passage (14;51) includes a valve (16;53) which can close the inlet passage (14;51). When this happens, a by-pass valve (19;42) opens and connects the inlet (12;39) direct to the housing outlet (13;40). An anti-backflow valve (17;50) is provided in the outlet passage (15;47) to prevent fluid passing back down the outlet passage to the filter element. The filter element (11;34) can then be changed. A re-pressurization valve (23;58) is provided to pass fluid to the element (11;34) while the inlet passage (14;51) is still closed and a vent port (21;55) vents air from the element during this re-pressurization. Once re-pressurization is complete, the vent port (21;55) and the re-pressurization valve (23;58) are closed and the inlet valve (16;59) opened so that filtration recommences.

摘要: A fuel filter has a semipermeable spiral baffle with an open circuitous spiral channel between spiral flights of filter media. Fuel may pass radially (inwardly or outwardly) through the media which preferentially slows water and other contaminants such that the contaminants tend to "settle" in the channel and slowly flow out of the baffle to a contaminant collection zone.
