Abstract: A filter element, in particular for cleaning combustion air for internal combustion engines, arranged in a filter housing composed of a filter medium having at least one end face on which a resilient, synthetic resin sealing bead is arranged which contacts a sealing contour on the filter housing. An identifier element which is completely covered by the sealing bead is arranged in the filter element, for example, within an end disk thereof.

Abstract: A filter cartridge (16), especially for installation in an air filter of an internal combustion engine having a housing (10) with an inlet (12) for untreated air and an outlet (13) for clean air, the filter cartridge preferably being made of a pleated filter medium, and being provided with sealing elements on end plates (18, 19) arranged at the axial end faces of the filter cartridge. A support body (17) is provided on the inner wall of the filter cartridge with support surfaces (23) for axially and radially positioning the filter cartridge. A seal element (26) extending axially along the support body is also provided in the area of the support body.

Abstract: A fuel module including a fuel filter located on a valve block 10 and having a replaceable filter insert 14 in a filter housing 11. The fuel module also has a manually-operable feed pump 31, a connection 8, located on the valve block 10, for fuel supply, a connection C for fuel return, two connections A, D for a mechanical feed pump and a connection E to the injector pump, the manually-operable feed pump 31 containing two identically-constructed valves 23, 24.

Abstract: An oil separator for the gases of the crankcase ventilating system of an internal-combustion engine has a filter element through which the breathing gases flow and from which the separated oil is returned via an oil return into the oil tank 4. The blow-by gases, from which the oil was removed, are supplied to the air intake system of the internal-combustion engine. A vacuum generator is provided which generates a specified constant vacuum for the sucking-off of the blow-by gases. In addition, an air oil removal element that separates the oil has microfibers which are made of fiber glass material.
