Patent number: 7905203Abstract: In an oil cooler, a heat exchange core is housed in a casing including a cylindrical sidewall part in a way that a cooling water passage is formed around a heat exchange core. The heat exchange core includes inlet-side and outlet-side oil passages, and enables oil to be delivered from the inlet-side oil passage to the outlet-side oil passage. Inlet and outlet pipes are connected to the sidewall part. The inlet pipe forms a cooling water inlet passage in communication with the cooling water passage. The outlet pipe forms a cooling water outlet passage in communication with the cooling water passage. Outward of the inlet-side oil passage, an outwardly swelling part is formed in the sidewall part of the casing. This arrangement avoids the oil cooler being constructed in a large size and avoids decreasing the heat exchange efficiency of the oil cooler, and also prevents cavitation and erosion from occurring due to the flow of cooling water in an area corresponding to the inlet-side oil passage.Type: GrantFiled: August 11, 2008Date of Patent: March 15, 2011Assignees: Honda Motor Co., Ltd., Denso CorporationInventors: Yuichi Tawarada, Masashi Furuya, Yoshihiro Tajima

Patent number: 7905204Abstract: Constant pressure internal combustion engine having compression and expansion chambers of variable volume, an elongated combustion chamber of substantially constant volume between the compression and expansion chambers, and a fuel inlet for introducing fuel into the combustion chamber where it mixes with compressed air from the compression chamber to form a mixture of fuel and air that burns as it travels through the combustion chamber. In some embodiments, the combustion chamber is folded back upon itself and has a rough, twisting interior side wall, with long, sharp protrusions extending inwardly therefrom and forming hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber. These protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air in the combustion chamber.Type: GrantFiled: July 17, 2006Date of Patent: March 15, 2011Assignee: Zajac Optimum Output Motors, Inc.Inventor: John Zajac

Patent number: 7900604Abstract: A dampening stop pin that reduces a needle velocity at the time when the needle valve of a fuel injector is about to be seated in a closed position. A gap between a bottom surface of the stop-pin flange and a sealing seat of a nozzle is provided to compress the fuel trapped therein to form a fuel cushion that dampens the closing motion of the needle. Moreover, a diametrical clearance between an outer circumferential edge of the flange and an inner surface of a needle spring cage must be sized to prevent undesired high pressure from building up in the gap by venting a quantity of compressed fuel while still permitting the fuel cushion to dampen the closing force of the needle.Type: GrantFiled: June 15, 2006Date of Patent: March 8, 2011Assignee: Siemens Diesel Systems TechnologyInventor: Olaf Enke

Patent number: 7836678Abstract: A propulsion system for use in a liquid or gas fluid is provided including an axially-extending funnel-shaped conduit, a flow generator, a power source, and, optionally, an airfoil-shaped wing. The funnel-shaped conduit has outer walls forming an inner fluid passageway, an upper edge defining a fluid inlet, and a lower edge defining a fluid outlet. The optional airfoil-shaped wing is connected to and circumferentially surrounds the funnel-shaped conduit upper edge. The flow generator is rotatably mounted about the axis of the funnel-shaped conduit and is configured to force the fluid from the fluid inlet rearward through the fluid outlet. A forward force is produced by the combination of both thrust from the flow generator plus the lift force created as the flow generator draws the fluid across the annular airfoil-shaped wing and inwardly through the fluid inlet forcing the fluid rearward to exit out of the fluid outlet.Type: GrantFiled: March 25, 2008Date of Patent: November 23, 2010Inventors: Gaofei Yan, James Dees
