Abstract: A removable, spiral vane insert for receipt by a centrifuge rotor enclosure includes a unitary, molded plastic spiral vane portion including a spiral vane module and a baseplate that are all integrally joined together. The spiral vane portion further includes a tubular sleeve having a longitudinal axis corresponding to the axis of rotation for the rotor.

Abstract: A centrifuge for separating particulate matter from circulating fluid includes a centrifuge enclosure including a housing and a base joined together so as to define a hollow interior. A rotor is positioned in the hollow interior and is supported by the base in a manner to permit rotary motion of the rotor relative to the centrifuge enclosure. A coalescing filter assembly is secured to the rotor and is constructed and arranged for removing oil aerosol from a blowby gas which is introduced into the centrifuge. A roller bearing, press fit into the centrifuge housing, receives a portion of the coalescing filter assembly.

Abstract: The invention concerns a filter for liquid circulating in an engine unit or in hydraulic equipment including a tank (1) cooperating with a closure element (2) with a filtering cartridge (3) inserted in the tank (1) and adjusted therein by threadedly engaging the closure element (2) with the tank (1). The cartridge (3) includes a filtering material (4) having at one of its ends a first flange (5) and at the other of its ends a second flange (6) that includes a peripheral seal (8) designed to be sealingly clamped between an end of the tank and the closure element (2) when the tank (1) is threadedly with the closure element (2). The invention is characterized in that it includes at least one element forming a stop (9, 91) provided on the second flange (6) and/or on the closure element (2) and/or on the tank (1), the element forming a stop (9,91) being designed to control clamping of the peripheral seal (8) with the closure element (2).
