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.

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.

Filtration assembly including a body, a head, a cartridge and means for retaining the cartridge on the head and the body, and corresponding filtration cartridge

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.

This invention relates to a hollow element designed to cooperate with a filter cartridge of a filter assembly for fluid circulating in an engine or a hydraulic equipment, of the type with support means for a filter medium included in the said cartridge, the said support means extending from connection means and designed with recesses between them through which the said fluid is free to flow, characterized in that the said support means extend from one of the said connection means to another following a path defining a spiral portion with a substantially constant slope.

Hollow element for the support of a filter medium including support means in the form of spiral portions with a substantially constant slope, and a corresponding filter assembly

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.

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.

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.

A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a stand pipe that is constructed and arranged to deliver fluid. A vane assembly is adapted to receive fluid from the stand pipe. The vane assembly includes a liner and a plurality of vanes. The liner defines an inner cavity and the vanes extends within this inner cavity. Each of the vanes has a radially outer edge portion and integrally formed with the liner and an opposite free edge. The vanes are oriented in a parallel relationship with the stand pipe, and the free edges of the vanes define a stand pipe passage in which the stand pipe is received.

The invention relates to a filter cartridge ( ) to be inserted in the filter feed trough of a filter for fluid flowing in a hydraulic motor or apparatus and for cooperating with a center tube ( ) of said filter, said cartridge having a filter medium ( ) and at least one end flange ( ) joined to said filter medium, characterized in that said end flange ( ) is extended by a projecting part ( ) defining a cavity for lodging a gasket ( ), and in that said gasket has at least one pressurizing duct from the inside of said cavity. The invention also relates to a corresponding filter cartridge ( )/gasket ( ) assembly wherein said gasket has at least three lobes defining three fluid receiving areas.

A maintaining device for a filter medium having a stack of filtration disks presenting a central aperture, characterized in that it comprises a first flange with at least one central opening, a second flange and at least one perforated first central element intended to operate together with said central aperture of said stack of filtration disks, said first central element being integral at one its extremities with said second flange and being provided at its other extremity with ratchets intended to operate together with said central opening of said first flange.

Filter apparatus having a maintaining device for centering a stack of filtration disks

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

A filter and filtering cartridge with a removable center tube, for the filtering of fluids. The invention relates to a filter for circulating fluid of the type consisting of a filtering cartridge inserted in an outer shell, with the outer shell being intended to be removably connected to a base. The outer shell cooperates with an independent and removable center tube. A filtering cartridge is mounted in the outer shell around the independent and removable center tube which extends longitudinally inside said outer shell over at least a substantial part of the length of the outer shell. The filtering cartridge is longitudinally restrained inside said outer shell in part by the removable center tube.
