Abstract: An internal combustion engine crankcase ventilation rotating coalescer includes an annual rotating coalescing filter element, an inlet port supplying blow by gas from the crankcase to the hollow interior of the annular rotating coalescing filter element, and an outlet port delivering clean separated, air from the exterior of the rotating element. The direction of flow by gas inside-out, radially, outwardly from the hollow interior to the exterior.

Abstract: A filtration assembly is provided for a liquid flowing in an engine or hydraulic equipment, of the type including a body with a head on top thereof, and a cylindrical member for holding a filtration cartridge containing a filtration medium defined by an upper flange and a lower flange. The upper flange is coupled to the head by a first longitudinal retainer. The cartridge includes a second longitudinal retainer interacting with the body. The first retainer having a longitudinal tensile strength lower than the longitudinal tensile strength of the second retainer.

Abstract: A dual stage filter includes an outer filter with a first media and an inner filter with a second media. A barrier is between the first media and the second media. The barrier directs fluid flow between the first and second media. The barrier creates a flow path between the first and second media, such that a working fluid, which is desired to pass through the first and second media, is directed by the barrier and flows through the second media, and such that another fluid, which is not desired to pass through the second media, is directed by the barrier and separates from the working fluid. Using the barrier, the dual stage filter can employ either or both upward flow and downward flow to achieve efficient fluid separation, for example fuel water separation in an engine fuel filter.

Abstract: A filter cartridge includes a filtering medium having a tubular cavity and an upper flange having an orifice communicating with the tubular cavity. A gas-permeable element closes off the orifice and has a greater permeability than the filtering medium, and less resistance to gas flow than the filtering medium.

Abstract: The object of the invention is a filter cartridge of a filter assembly for fluid circulating in an engine or a hydraulic machine, designed to cooperate with a central tube, said cartridge comprising a filtration medium and at least one end flange integrated with said medium, said flange projecting to form a cavity for a gasket, characterized in that said cavity incorporates radial retention means for said gasket.

Abstract: A fuel water separator system includes a fuel tank for storing fuel and a fuel water separator fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side that is fluidly coupled to the fuel water separator for pumping fuel from the fuel water separator. The fuel pump has a high pressure side where the fuel has a higher pressure than at the suction side. A water pump, such as a venturi or a jet pump, is fluidly coupled between the fuel water separator and the fuel tank for pumping the water from the fuel water separator into the fuel tank. The water pump is fluidly coupled to the high pressure side of the fuel pump to receive the fuel at the higher pressure to drive the water pump.

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: The purpose of the invention is a device to circulate air between the interior and the exterior of an enclosure (1) intended to contain air and a liquid, in which the enclosure (1) is an element intended to be installed in a vehicle, characterized in that it consists of at least two separate conduits (2, 3), connecting the interior of said enclosure (1) to its exterior, in which one conduit (2) is dedicated to the intake of air under normal conditions of pressure difference between the interior and the exterior of said enclosure (1), and one conduit (3) is dedicated to the release of air under normal conditions of pressure difference between the interior and the exterior of said enclosure.

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.
