摘要:
A filtering apparatus has a filter housing with a structure forming a recessed region on the filter housing configured to be directly engaged by a filter element in order to form an integral seal. The structure may include one or more protrusions that extend into the filter element itself, or into respective recess(es) of the filter element.

A centrifuge includes a housing that defines a fluid inlet port to supply fluid to the centrifuge and an axle cavity fluidly coupled to the fluid inlet port. A bearing is received in the axle cavity. A check valve is disposed in the axle cavity to minimize tampering, and the check valve is configured to control flow of the fluid from the inlet port. A rotor is configured to separate particulate matter from the fluid. The rotor includes an axle rotatably received in the bearing, and the axle defines a fluid passage to supply the fluid to the rotor. The check valve is normally biased towards a closed position where the flow of the fluid is shutoff. The axle is configured to open the check valve when the axle is received in the bearing.

A pressure gradient dosing system is provided for a fluid supply system. A flow passage has first and second pressure zones having a pressure gradient therebetween. An additive reservoir in an additive delivery system responds to the pressure gradient to release additive to the flow passage.

The present invention provides a filter assembly containing a filter element and a container as a depot for a liquid additive. The container can include an inlet and an outlet, which are configured to allow a liquid to flow into the container mix with the contained additive and then flow out into the system. It has been observed that a liquid flowing through a filter assembly exhibits a pressure gradient within the filter. Consequently, the inlets and outlets to the container can be positioned to take advantage of the pressure gradient to enhance the addition of the additive to the liquid in the filter assembly.

A rotor assembly for use as part of a centrifuge for the separation of particulate matter from a fluid includes a collection chamber housing a particulate separation mechanism and a drive chamber including a Hero turbine which assembles to the collection chamber and which is separable from the collection chamber. The interfit between the drive chamber and the collection chamber imparts any drive chamber rotation due to the Hero turbine directly to the collection chamber for rotation and for particulate separation. By making the drive chamber separable from the collection chamber, the collection chamber can be discarded with its accumulated sludge, allowing the drive chamber to be reused.

A filtering system (10) is provided for filtering working fluid from a machine (12) and includes a cleanable filter (16) and a centrifuge (82) where filter capacity is too low for a permanent filter yet flow rate is too high for a centrifuge. The system transfers the contaminant storage function from the cleanable filter to the centrifuge. A simple effective centrifuge is provided.

A self-driven centrifuge for separating particulate matter out of a circulating liquid includes a base plate and a rotor shell. The base plate has a center tube extending therefrom along a longitudinal axis. The center tube is constructed and arranged to deliver fluid containing particulate matter. A rotor shell has an inner cavity and a plurality of spiral vanes extending along the longitudinal axis within the inner cavity. The spiral vanes extend spirally around the center tube and the spiral vanes are integrally formed with the rotor shell. In one form, spiral vanes are also formed on the base plate and are nested in between the spiral vanes of the rotor shell.

A cone-stack centrifuge for separating particulate matter out of a circulating liquid includes a cone-stack assembly which is configured with a hollow rotor hub and is constructed to rotate about an axis. The cone-stack assembly is mounted onto a shaft centertube which is attached to a hollow base hub of a base assembly. The base assembly further includes a liquid inlet, a first passageway, and a second passageway which is connected to the first passageway. The liquid inlet is connected to the hollow base hub by the first passageway. A bearing arrangement is positioned between the rotor hub and the shaft centertube for rotary motion of the cone-stack assembly. An impulse-turbine wheel is attached to the rotor hub and a flow jet nozzle is positioned so as to be directed at the turbine wheel. The flow jet nozzle is coupled to the second passageway for directing a flow jet of liquid at the turbine wheel in order to impart rotary motion to the cone-stack assembly. The liquid for the flow jet nozzle enters the cone-stack centrifuge by way of the liquid inlet. The same liquid inlet also provides the liquid which is circulated through the cone-stack assembly.

A bypass circuit centrifuge for separating particulate matter out of a circulating liquid includes a hollow and generally cylindrical centrifuge bowl which is arranged in combination with a base plate so as to define a liquid flow chamber. A hollow centertube axially extends up through the base plate into the hollow interior of the centrifuge bowl. The bypass circuit centrifuge is designed so as to be assembled within a cover assembly and a pair of oppositely disposed tangential flow nozzles in the base plate are used to spin the centrifuge within the cover so as to cause particles to separate out from the liquid. The interior of the centrifuge bowl includes a plurality of truncated cones which are arranged into a stacked array and are closely spaced so as to enhance the separation efficiency. The stacked array of truncated cones is sandwiched between a top plate positioned adjacent to the top portion of the centrifuge bowl and a bottom plate which is positioned closer to the base plate. The incoming liquid flow exits the centertube through a pair of oil inlets and from there flows through the top plate. The top plate in conjunction with ribs on the inside surface of the centrifuge bowl accelerate and direct this flow into the upper portion of the stacked array of truncated cones. As the flow passes through the channels created between adjacent cones, particle separation occurs as the liquid continues to flow downwardly to the tangential flow nozzles.

A V-shaped filter includes a V-shaped carrier frame, first and second cartridge frames movably mounted to the carrier frame, and first and second filter element cartridges removably and replaceably mounted to the first and second cartridge frames, respectively. The first and second cartridge frames are movable to an inserted position in the V-shaped carrier frame providing an installed condition with the first and second cartridge frames forming a V-shape, and are movable to an extended position extending beyond the V-shaped carrier frame and providing a replacement-service condition.
