20080202081 | FLUID FILTER - The invention relates to a fluid filter ( | 08-28-2008 |
20100326392 | FILTER SYSTEM - A liquid filter system, having an annular first filter element that separates a crude side from a clean side in a first filter chamber and a first plug, which projects axially and eccentrically with respect to a longitudinal center axis of the first filter element and extends axially into a first plug receptacle after insertion in the first filter chamber. A annular second filter element that separates a crude side from a clean side in a second filter chamber and a second plug, which projects axially and eccentrically with respect to a longitudinal center axis of the second filter element and extends axially into a second plug receptacle after insertion in the second filter chamber, and wherein the filter elements differ from one another at least in that the plugs have at least one of different eccentricities and shapes. | 12-30-2010 |
20110017650 | LIQUID FILTER, ESPECIALLY OIL FILTER - An oil purifying liquid filter, having an annular ring element receiving space, wherein the ring element has two axial end disks, a cover selectively fastened to a housing to close the receiving space, an inlet that is formed within the housing on a crude side, an outlet that is formed within the housing on a pure side, a first additional opening that is formed within the housing, a second additional opening that is formed within the cover, a first closure that is formed on the first end disk of the filter element in order to close the first additional opening, and a second closure that is formed on the second end disk of the filter element to selectively close the second additional opening. | 01-27-2011 |
20110089091 | FILTER DEVICE - A filter device having a filter element received in a filter housing, the filter housing has an inlet and an outlet. The filter element separates a crude chamber that communicates with the inlet from a pure chamber that communicates with the outlet. The filter element has an axially and eccentrically projecting plug, which in an inserted state, is plugged into a plug receptacle formed within the filter housing, and wherein at least one signal generator recognizes at least one of a presence and an absence of the plug in the plug receptacle, generating at least one signal. | 04-21-2011 |
