    Abstract: An oil capturing device for capturing oil from crankcase gases. The oil capturing device includes a housing containing a central chamber and a rotor disposed in the central chamber. The rotor includes a shaft rotatable about an axis and a flange extending from the shaft towards the inner wall of the central chamber. The flange is in contact with the inner wall, and spirals along the shaft so as to define a gas passage interconnecting the inlet to the first port. The gas passage provides a passage for crankcase gases to flow from the inlet to the first port, and narrows as it proceeds from the inlet to the port so as to compress crankcase gases travelling from the inlet to the first port. The rotor may be operable by a motor, pulley connected to the engine, or a turbine driven by the engine's exhaust.

  • Publication number: 20090304526
    Abstract: A pump apparatus includes a gear pump assembly interposed between top and bottom drive gear assemblies, and coupler assemblies interposed between a bottom of the top drive gear assembly and a top of the gear pump assembly, and between a top of the bottom drive gear assembly and a bottom of the gear pump assembly. The drive assemblies rotate a pre-feed auger. A cyclone screen located within a cyclone housing is positioned over a shaft of the pre-feed auger and interposed between a blade of the pre-feed auger and the bottom drive gear assembly. An intake housing is positioned over the blade of the pre-feed auger, and regulates fluid intake into the pump. As fluid is taken into the pump, it is caused to spin by the action of the auger. This causes solids to be separated from the fluid and to be expelled through exhaust ports in the pump apparatus. As a result, fewer solids are permitted to travel northward with the pumped fluid, thereby helping to protect the components of the pump.

  • Publication number: 20090194484
    Abstract: Novel filter elements for sequestering acids from oil or fuel, the strong base floes that comprise the filter elements, and methods of their preparation and use are disclosed. The filter elements comprise a mechanically linked interlocking fiber matrix interspersed with strong base particle floes wherein the strong base particles constitute at least 30% by weight of the filter element. Certain filter elements may be useful for sequestering acids or neutralized acids in certain oils or fuels, for example, the acids originating in the combustion and lubrication system of an internal combustion engine or those contained in oils in an oil circulation system. Other filter elements may be useful for reducing oxidation of an oil.

  • Patent number: 7510662
    Abstract: A contaminant-flushing machine for removing contaminants from a container, such as an engine transmission, air-conditioner coil, or transmission cooler, which includes hoses for coupling to the transmission cooler and a pump for circulating fluid through the hoses and the transmission cooler, and a fluid filter having a reduced tendency towards causing vaporization of the fluid. Also included in the contaminant-flushing machine is an automatic aeration system for injecting air into the circulating fluid at predetermined intervals. Additionally, a reverse flow piping circuit is included to permit automatic and electric manipulation of the flow direction of fluid through said transmission cooler while at the same time not altering the direction of flow of fluid through the pump. The flow reversals are repeated with a cycle of three (3) seconds in one direction followed by a flow in the other direction of one-fourth (¼) of a second, thereby creating an overall flow of fluid primarily in one reverse direction.
