Abstract: The invention relates to a centrifugal separator for separating oil and/or solid particles entrained in an air stream, particularly for de-oiling crankcase gases of an internal combustion engine. The centrifugal separator has a mixture inlet for the oil and/or solid particle containing air, an air outlet for the cleaned air and an oil outlet for oil and/or solid particles. It has a stator configured as a housing in which a rotor is disposed, which is operably connected to a drive. A basket is non-rotatably connected to the rotor. The basket has a substantially cylindrical part, which extends in the direction of the mixture inlet and substantially parallel to the stator.

Abstract: A process is described for producing filter elements which contain a cross-wound yarn as the filter material, wherein twisted yarn of fine individual fibers is roughened to enhance its filtering action. The yarn may be heat-resistant and the filter element may be used as a soot filter in the exhaust gas stream of an internal combustion engine. Before the yarn is wound up, fiber tufts are broken up by pulling the yarn under tension over a moving roughening surface, the direction of movement of the roughening surface differing by an angle alpha from the direction of movement of the yarn in the area of contact between the yarn and the roughening surface, and the angle alpha being selected in relation to the twist of the yarn, particularly so that the threads of the yarn in contact with the roughening surface are oriented transversely to the direction of movement of the roughening surface. The process produces a roughened yarn which provides the required high filter performance for a soot filter.

Abstract: A free-jet centrifuge which, in contrast to prior art centrifuges which are braked by bearing friction, includes a device for braking the rotor when the oil pressure falls below a predetermined value. The rotor is mounted in a slide bearing (12), which simultaneously forms the centrifuge oil inlet (23), and also is provided with a roller bearing (19), which minimize bearing friction and enables the rotor to attain the highest possible rotational speeds. Friction partners (15a, 15b) are disposed on the centrifuge housing (10) and rotor (11) and are pressed against one another by a spring (20) when the oil pressure drops below operating pressure, to stop the rotor in order to minimize run-on of the centrifuge and the noise and bearing wear associated with run-on.
