摘要： 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.

摘要： A centrifuge for processing a flow of oil in order to remove particulate matter includes a mounting base defining a drain passageway, a drain conduit connected to the mounting base, a unitary housing connected to the mounting base, and a cone-stack subassembly which is positioned in and cooperates with the unitary housing. The mounting base is constructed and arranged to mount directly to a portion of a vehicle engine (or other equipment) and the drain conduit provides a return path to sump for oil from a remote engine (or equipment) location. The unitary housing is an injection molded plastic component including both a main body portion and an integral oil fill port. The oil fill port is substantially cylindrical with a longitudinal axis which is parallel to the axis of rotation for the rotor portion of the centrifuge.

摘要： A coalescing filter for separating oil from a blowby gas stream includes a coalescing filter element designed with a plurality of relatively small flow-through pores which have the potential for creating a high restriction when wetted due to the surface tension which results. In order to reduce the restriction level, the coalescing filter is attached to a rotating component, such as a gear, so that rotary motion is imparted to the coalescing filter and centrifugal force is generated across the plurality of flow-through pores. By generating centrifugal force, any oil which might otherwise remain in said pores so as to clog the pores is spun out so that the pores of the coalescing filter element remain in a "dry" condition such that any restriction to continued flow is substantially lower than the restriction level when the pores are wetted.
摘要翻译：用于从窜气流中分离油的聚结过滤器包括设计有多个相对小的流通孔的聚结过滤元件，其具有由于所产生的表面张力而润湿时产生高限制的可能性。为了降低限制水平，将聚结过滤器附着到诸如齿轮的旋转部件上，使得旋转运动被赋予聚结过滤器，并且跨过多个流通孔产生离心力。通过产生离心力，可以将任何可能残留在所述孔中以阻塞孔的油旋转出来，使得聚结过滤元件的孔保持在“干”状态，使得对持续流动的任何限制都显着低于当毛孔被润湿时的限制水平。

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 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 honeycomb-like insert is assembled into the flow jet nozzle in order to reduce inlet turbulence and improve the turbine efficiency.

摘要： An inertial gas-liquid impactor separator includes an inertial impactor collector having an impactor surface extending diagonally relative to axially accelerated flow, which surface is preferably a cone having a leading tip axially facing and axially aligned with the acceleration nozzle. In a further aspect, first and second inertial impactor collectors are provided in series, with an orifice in the first inertial impactor collector providing a nozzle for the second inertial impactor collector. Improved performance is provided by reducing the extent of the stagnation region to change from a narrow band particle size range to a wider band range and to shift cut-off size. An inertial gas-liquid impactor separator has a perforated layer of coalescence media having at least one aperture through which the gas-liquid stream flows. Improved performance is provided by increased penetration of the flow into the media patch and thereby enhancing particle capture by interception, impaction and diffusion.

摘要： An apparatus, system and method to maximize ultrafine meltblown fiber attenuation. The nozzle apparatus includes a polymer streaming channel, at least one gas delivery channel, a restricted throat area, and a bounded expansion area. In some embodiments, the nozzle comprises a two-dimensional converging-diverging Laval nozzle geometry. The gas delivery channels may provide the gas under a pressure exceeding critical pressure, such that the gas achieves supersonic speeds at the restricted throat area. The bounded expansion area may stabilize such supersonic speeds, thus maximizing ultrafine meltblown fiber attenuation while minimizing the formation of fly and other defects.
