Patent number: 5197443Abstract: A fuel system for a diesel truck has a first fuel tank (80) and a second fuel tank (82). A siphon line (90) is open to the lower portions of the tanks and extends above the upper portions of both tanks. A manually operated priming pump (98) is used to remove air from the siphon line. Fuel is delivered from the first tank to the engine of the truck through a fluid delivery line (84). As fuel is drawn from the first tank, the fuel levels in the tanks equalize as the result of flow through the siphon line. Fuel not consumed by the engine is returned through an overflow line (86). The returning fuel is warmed as a result absorbing energy during pumping and having been in close proximity to the engine. A three-way control valve (88) directs the warm returning fuel to either the first or second fuel tank in response to the temperature sensed by a temperature sensor (94).Type: GrantFiled: June 13, 1991Date of Patent: March 30, 1993Assignee: Parker Hannifin CorporationInventor: David H.

Patent number: 5082426Abstract: A jet pump structure for a fuel tank having first and second chambers therein includes first, second and third fuel pipes all of which are connected to a vacuum chamber provided within the fuel tank. The first pipe returns oversupplied fuel into the vacuum chamber, the second pipe transfers fuel stored in the first chamber into the vacuum chamber, and the third pipe receives the fuel from the first and second pipes and discharge same into the second chamber. A flow guide member is provided within the first pipe, which receives the oversupplied fuel to form same into a swirl flow. The swirl flow is ejected from the first pipe as a jet flow into the vacuum chamber to provide a vacuum therearound within the vacuum chamber. The ejected swirl flow further works to seal the vacuum chamber against the third pipe so that the vacuum generated within the vacuum chamber is prevented from being released through the third pipe to effectively suck the fuel from the first chamber.Type: GrantFiled: July 14, 1989Date of Patent: January 21, 1992Assignees: Nissan Motor Company, Limited, Jidosha Denki Kogyo Kabushiki KaishaInventors: Michiaki Sasaki, Kiyokazu Yamamoto, Toshiyuki Matsuki

Patent number: 4747429Abstract: An emergency fuel transfer accessory adapted for mounting in a vehicle's fuel system is disclosed. In a normal or first mode the accessory directs fuel through the confidential fuel system of the vehicles. The accessory includes a valve adapted for utilizing the action of the vehicle's fuel pump for drawing fuel from an external fuel source and directing that fuel through the fuel system of the accessory fitted vehicle into said vehicles fuel tank. The valve is further adapted in another mode to transfer fuel from the accessory fitted vehicle outward to an external fuel source. In a fourth mode, the valve is adapted to direct fuel from a first external fuel source, through the accessory fitted vehicle's fuel system, and thereafter discharging that fuel into a second external fuel source. The valve includes a plurality of channels which are positionable to connect with conduits connecting the accessory vehicle's fuel pump, fuel tank and carburetor.Type: GrantFiled: December 11, 1986Date of Patent: May 31, 1988Inventor: Lowell W. Sundstrom, Jr.

Patent number: 4694870Abstract: A vented fuel system for a vehicle includes a plurality of fuel storage tanks and a fuel sump tank with at least one fuel storage tank positioned on each side of the vehicle. The sump tank is positioned on the vehicle between the fuel storage tanks and at a lower elevation than the fuel storage tanks. Each of the fuel storage tanks is connected by a fuel line to the sump tank and all of the fuel storage tanks are interconnected by air transfer lines. One of the fuel storage tanks on each side of the vehicle is provided with a filler spout and a vented fuel cap assembly for closing the filler spout. All of the fuel tanks can be filled from either side of the vehicle, and during refueling, air is expelled from the closed vented fuel cap assemblies and the open filler spout. The plurality of air transfer lines prevent air entrapment in any of the tanks by transferring air between the tanks and subsequent venting of the air through either or both vented fuel cap assemblies.Type: GrantFiled: June 13, 1986Date of Patent: September 22, 1987Assignee: Caterpillar Inc.Inventor: Robert M. Vize

Patent number: 4620568Abstract: A fuel flow diverting system is provided for a diesel engine powered vehicle including an auxiliary power system driven from the engine of the vehicle when the latter is stationary and wherein the vehicle is provided with primary and secondary fuel tanks with fuel supply and return lines being provided for each tank. The fuel diverting system is operative when the auxiliary power system is not operating and the vehicle is being operated in an over-the-road mode, to draw engine fuel from and return excess engine fuel to the primary tank. The fuel diverting system is further operative, when the vehicle is stationary and the auxiliary power system drivable when the vehicle engine is actuated, to supply fuel to the engine from the auxiliary fuel tank only and to return fuel from the engine to the auxiliary fuel tank only.Type: GrantFiled: October 9, 1985Date of Patent: November 4, 1986Inventors: Harold A. Sumerford, Melvin R. Collins

Patent number: 4383590Abstract: A tractor having two power units supported on respective frame portions which are pivotably connected in tandem, each power unit operatively connected to its respective fore or after axle which respectively mounts four or six wheels. The frame portions supporting the power units are joined between the fore and aft axles by vertical and horizontal solid steel pivotable shafts so as to be pivotable within limits about both a vertical axis and a horizontal axis aligned with the longitudinal axis of the tractor. Hydraulic piston and cylinder units extending from the frame portion of one power unit to the other on either side of the vertical pivotable shaft provide steering from controls located in a cabin suspended by an inverted "U" structure included in the frame portion of the after power unit. Both power units are provided with large capacity fuel tanks which extend transversely above each set of wheels and have a configuration whereby they function as fenders or mudguards.Type: GrantFiled: January 31, 1979Date of Patent: May 17, 1983Inventor: Cornelis van der Lely

Patent number: 4287908Abstract: A valve assembly for selectively connecting either one of a pair of fuel supply tanks through supply and return lines to and from a combustion engine while isolating the other tank from communication both with the selected active tank and with the engine. The valve includes first and second chambers dedicated respectively to supply and return service. Valving elements in the chambers are operated by a selector shaft shiftable between first and second positions corresponding to the first and second tanks. The valve is advantageously ported in a manner which only requires a single supply line and a single return line to and from the engine.Type: GrantFiled: July 30, 1980Date of Patent: September 8, 1981Assignee: Dana CorporationInventor: David N. Storgard

Patent number: 4270621Abstract: A tractor with two engines arranged in tandem, each carried by a frame portion pivotable relative to the other counterbalances about a vertical axis under the rear engine. The body of the tractor is narrow forward and to the rear wherein axles for front and rear sets of ground engaging wheels extend laterally and mount six wheels each. The front engine and rear engines extend forward of the respective front and rear sets of ground wheels. The front frame portion is turnable axially relative to the rear frame portion under the rear engine and steering is accomplished by the relative pivoting of the portions about the aforesaid vertical axis. A fuel tank forms a guard over the rear set of wheels and includes a depression for an operator's seat. The fuel tank has a central partition and is optionally hinged in its outer portions whereby the width of the tractor is reduced by removing the outer wheels and pivoting the outer portions of the fuel tank to the rear.Type: GrantFiled: January 17, 1979Date of Patent: June 2, 1981Inventor: Cornelis van der Lely
