A disposable, cone-stack, self-driven centrifuge rotor assembly (20) for separating particulate matter out of a circulating flow of oil includes first and second rotor shell portions (22 and 23) which are injection molded out of plastic and joined together by ultrasonically welding engaging edges (26 and 27) so as to create an enclosing shell with a hollow interior. An injection molded, plastic support hub (25) is assembled into a central opening in the lower half (23) of the rotor shell and extends upwardly into the hollow interior. An injection molded, plastic bearing/alignment spool (24) is assembled into a central opening in the upper portion (22) of the rotor shell and extends downwardly into the hollow interior. A cone-stack subassembly (21), including a plurality of individual separation cones which are injection molded out of plastic, are arranged into an aligned stack and positioned within the hollow interior and cooperatively assembled between the support hub (25) and the bearing/alignment spool (24). The all plastic construction for the centrifuge rotor assembly (20) allows the entire assembly (20) to be disposed of without any disassembly required.

An exhaust aftertreatment filter (20) includes a housing (22) extending axially along an axis (28) between distally opposite first and second ends (30 and 32), a first port (34) at the first end of the housing, a second port (36) also at the first end of the housing, one of the first and second ports being an inlet, and the other being an outlet, the housing having an intermediate section (38) between the distally opposite ends, the intermediate section having a given cross sectional area A1 along a sectional plane transverse to the axis, a catalytic exhaust filter element (24) in the intermediate section and entirely filling the cross sectional area A1 except for a smaller cut-out (40) in the exhaust filter element of cross sectional area A2, the exhaust filter element having a cross sectional area A3 = A1-A2, a transfer tube (26) extending through the cut-out and communicating with the second port. Exhaust flows axially (42) through the exhaust filter element between first and second distally opposite sides (44 and 46) of the exhaust filter element, the first side facing the first end of the housing, the second side facing the second end of the housing, exhaust flowing axially through the exhaust filter element in one axial direction (42) and flowing through the transfer tube and cut-out in the opposite axial direction (48).
摘要:
A self-driven centrifuge (20) for separating particulate matter out of a circulating liquid includes a base (29) having a pair of tangential jet nozzles (34) for generating the self-driven force for the centrifuge. Connected to the base is a centrifuge shell (28) which defines a hollow interior space A disposable liner (24) is positioned within the centrifuge shell, allowing any sludge that is collected to be easily disposable without the need to clean other portions of the centrifuge. A hollow rotor hub (39) having a central axis of rotation is assembled to the base and extends through the hollow interior space. A support plate (33) is positioned within the hollow interior space and, in cooperation with the rotor hub, defines an annular flow exit opening (32) for the circulating liquid. Positioned within the hollow interior space is a separation vane module (21) which is constructed and arranged so as to extend around the rotor hub and positioned so as to be supported by the support plate. The separation vane module includes a plurality of axially-extending and spaced-apart separation vanes (25).
摘要:
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 (174) 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 (172) is positioned so as to be directed at the turbine wheel. The flow jet nozzle (172) is coupled to the second passageway (174) 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 (172) 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 honeycomb-like insert (170) is assembled into the flow jet nozzle (172) in order to reduce inlet turbulence and improve the turbine efficiency.

摘要:
An abrasive particle detection system includes a fluid circulation system, a probe assembly, a monitoring circuit, and an operator indicator The probe assembly includes an orifice from which a stream of fluid emerges, and a probe having a face upon which the stream at least partially impinges The probe face includes an insulative substrate and a conductive film formed on the substrate Abrasive particles in the fluid stream abrade the conductive film, changing its electrical resistance. A monitoring circuit is utilized to observe these changes, and when they correspond to a concentration above a pre-selected level, an operator indicator is triggered. The system may include an electronic controller coupled to the monitoring circuit. which can account for variables such as temperature, viscosity, and/or pressure in the fluid circulation system.

The fuel filter housing includes an outer surface with a connection interface for a fuel pump (22). This connection interface includes a flow inlet for fuel. The fuel pump which completes the integrated assembly includes a fuel inlet and a fuel exit which is directly connected to the flow inlet of the housing. Further, the fuel pump is directly mounted to the outer surface of the housing in a unitized-type of arrangement.
摘要:
A drain valve (102) for a fuel filter water separator (70) for an internal combustion engine has a first port (116) mating with the vent opening (100) of the separator (70), a second port (118) mating with the drain opening (98) of the separator (70) and a third port (120). The drain valve (102) is actuable between a closed position blocking communication of the first port (116) with the third port (120) and blocking communication of the second port (118) with the third port (120), and an open position providing communication of the first port (116) with the third port (120) and providing communication of the second port (118) with the third port (120). If the valve (102) is actuated to the open position when the engine is off, collected water and vent air each flow through the third port (120) but in opposite directions. If the drain valve (102) is actuated while the engine is running, pressurized fuel spray from the vent opening (100) and collected water from the drain opening (98) of the separator (70) each flow through the third port (120) in the same direction.
