The invention relates to a rotor (2) for a centrifuge (1), in particular for purifying lubricating oil in an internal combustion engine, wherein said rotor (2) is rotatably mounted in the centrifuge housing (10) and is provided with an impurity trapping element (4), the rotor (2) or the impurity trapping element (4) thereof are made of a plastic material and remote deflecting baffles (45) arranged in said impurity trapping element (4) can be removed from the centrifuge housing (10). The invention is characterised in that the inventive rotor (2) or the impurity trapping element (4) thereof comprises a lower part (41) and a top part (42), lower deflecting baffles (46) are provided in the lower part (41), top deflecting baffles (48) are provided in the top part (42), the lower (41) and top (42) parts are congruently welded to each other, the deflecting baffles (46, 48) are incorporated into the welded connection (40) and through openings (47'), which connect the chambers (45') of the impurity trapping element (4) delimited by said deflecting baffles (45) to each other in a fluid permeable manner, are embodied in at least one part of the deflecting baffles (45) on one or two sides of the welded connection (40) or on the plane thereof.
The invention relates to a separating device which is used to separate liquid particles from a gaseous particles. Known separating devices require an enlarged constructional area in order to have a conveying effect on the gaseous medium. As a result, said separating device (1) comprises a rotor (4) and a rotor shaft (6). Said rotor (4), which comprises conductor elements (7) which are arranged on the outer periphery (8) of the rotor shaft (6), is rotationally mounted in a housing (11) with the aid of the rotor shaft (6) thereof, and comprises a crude gas inlet (21), a pure gas outlet (15) and a fluid outlet (23). Essentially, the conductor elements (7) are arranged in a helical manner about said elements when seen in the longitudinal direction (13) of the rotor shaft (6). Said novel separating device combines the oil separating function with the medium conveying function, without the enlarging the constructional area.

IMPULSE CENTRIFUGE FOR CLEANING THE LUBRICATING OIL OF AN INTERNAL COMBUSTION ENGINE
The invention relates to an impulse centrifuge (1) for cleaning the lubricating oil of an internal combustion engine. Said centrifuge comprises a housing (10) having a cover (14), and a rotor (2) having recoil nozzles (34) and a dirt collecting area (4'). A piece of the rotor (2) holding the deposited dirt can be removed from the housing (10) and the rotor (2) is configured from interlinked elements. The inventive centrifuge is characterized in that the rotor (2) is constituted of three main components (21, 22, 23), namely an inner piece (21), a top piece (22) and a bottom piece (23); the top piece (22) and the lower piece (23) are interlinked die-cast or pressure-cast elements that are produced from incinerable plastic or light metal material and configure the piece of the rotor (2) that can be removed from the housing (10); the bottom piece (23) is annular, axially delimits the lower section of the dirt collecting piece (4) and comprises the recoil nozzles (34) and at least one nozzle channel (33) leading towards the recoil nozzles (34); and the removable piece of the rotor (2) configured by the top piece (22) and the bottom piece (23) is axially put on the inner piece (21) in a rotationally fixed manner sufficient to transmit the required torques and can be axially drawn of therefrom.
