An inlet port is located in the bottom closed end of one of the cavities and an outlet port is located in the other of the cavities. The surfaces that define the chambers can be configured such that the box can be oriented in different positions and still work, namely, in horizontal and vertical positions. When in the vertical position, the divider can include surfaces that are angled off of the horizontal plane and towards the inlet port such that water and debris will return to the inlet port via gravity.Type: GrantFiled: December 19, 2008Date of Patent: July 19, 2011Assignee: Honda Motor Co., Ltd.Inventor: Scott Jeffrey Volchko

Patent number: 7955408Abstract: This Invention relates to a kind of devices with no emission resulted for treatment of exhaust gas. The Device comprises a vessel having openings that serve only as inlet. At least two exchange sections are provided inside the vessel after inlet of exhaust gas. There is a gas chamber at each connection part between two sequential sections. The gas exchange chamber at the first gas exchange section has a through opening leading to outside atmosphere area, and at each one from the second to the last exchange section, there is a feedback pipe to connect to the inlet of the first stage of exchange section. With this configuration, on entering into the exchange section, exhaust gas will be ejected inwards and causes very strong entrainment, which makes the gas chamber become vacuum and sucks air with oxygen from atmosphere into gas chamber via the through opening to atmosphere.Type: GrantFiled: November 13, 2007Date of Patent: June 7, 2011Inventor: Yuguang Zhang

Patent number: 7938875Abstract: The present invention relates to a variable apparatus for separating oil from blow-by gas in an engine. More particularly, the variable apparatus of the present invention is installed in a baffle compartment of a cylinder head cover of the engine, and includes a partition wall (10), a cover (20) and an elastic member (30) that elastically supports the cover (20), thus separating oil from blow-by gas generated in the engine. The variable apparatus having the above-mentioned construction actively responds to the flow speed of the blow-by gas, thus markedly enhancing the ability to separate oil from blow-by gas even when the engine is operating at high speed.Type: GrantFiled: December 26, 2006Date of Patent: May 10, 2011Assignee: LG Chem, Ltd.Inventors: Young-Ki Son, Hee-Deog Kim

Patent number: 7927404Abstract: A downcomer for a reactor for downwardly conducting a multi-phase mixture, the downcomer includes a transport section having an interior comprised of inner and outer regions separated horizontally by a vertical barrier, and a baffle structure disposed on an inner surface of the barrier. The baffle structure is arranged to induce the mixture to flow in a downward generally helical path such that denser components of the mixture are centrifugally urged outwardly away from a center of the downcomer and less dense components migrate toward the center. The barrier includes openings enabling the denser components to travel from the inner region to the outer region to be collected herein.Type: GrantFiled: December 19, 2007Date of Patent: April 19, 2011Assignee: Chevron U.S.A. Inc.Inventor: Abdenour Kemoun
