摘要： A fuel selection device is provided for allowing a user to connect the cylinders of an internal combustion engine to a user-selected fuel source. The fuel selection device includes a housing that defines a cavity for receiving a moveable selector therein. The selector defining first, second, third and fourth flow paths. The first and second flow paths are used for flowing a first type (e.g., natural gas) of fuel from a fuel source to the cylinders of the engine. The second and fourth flow paths are used for flowing a second type of fuel (e.g., liquid propane vapor) from a fuel source to the cylinder. The selector is movable between a first position wherein first and second cylinders communicate with the first and second flow paths, respectively, and a second position wherein the first and second cylinders communicate with the second flow path and fourth flow paths, respectively.

摘要： An apparatus and method are provided for facilitating the cooling of engine coolant flowing through a radiator operatively connected to the engine of an engine-driven, electrical generator set. The engine has a crankshaft rotatable about a first axis and a radiator having a first side directed towards the engine and a second side. The apparatus includes a fan positionable on the second side of the radiator that is rotatable about a second axis generally parallel to and vertically spaced from the first axis. The apparatus includes a thermally responsive clutch having a driven portion. The clutch is movable between a first disengaged position wherein the driven portion is isolated from the crankshaft and a second engaged position wherein the driven portion rotates in unison with the crankshaft in response to a predetermined temperature. A fan drive system interconnects the driven portion of the clutch and the fan for translating rotation of the driven portion to the fan.

摘要： An air flow structure is provided for controlling the flow of air through an enclosure of a generator. The enclosure has first and second opposite ends and the generator includes an alternator and an engine driving the alternator. A first air flow generator draws ambient air into the chamber through the first end of the enclosure and directs the first portion of air in the chamber across the engine. A second air flow generator draws a second portion of the air over the alternator, and thereafter, combines the first portion of air directed over the engine and the second portion of air drawn over the alternator. The second air flow generator urges the combined air from the enclosure through the second end thereof.

摘要： A method is provided for cooling an engine driven, electrical generator set and for reducing the fan noise associated with operation of the same. The method includes positioning a fan on the first side of the radiator. The temperature adjacent a first side of the radiator is monitored and the fan is rotated in response to the temperature of the air on the first side of the radiator exceeding a threshold. The fan urges air through the radiator in order to cool the engine coolant flowing therethrough.

摘要： A relay is provided for a transfer mechanism which transfers power between a utility source and a stand-by electrical generator. The relay incorporates contacts formed from two distinct materials. A backing portion of each contact is formed from copper and a contacting portion is deposited on the backing portion. The contacting portion is formed from tungsten. The arrangement of the contact minimizes the potential for failure of the transfer mechanism when the transfer mechanism is exposed to significant current and/or heating during operation thereof.

摘要： A generator structure is provided having an improved air flow arrangement. The generator structure includes an enclosure having an interior for receiving an engine and an alternator therein. A roof structure is positioned on the enclosure and includes an eave portion and an attic portion. The eave portion has an inlet which communicates with the ambient air external of the generator structure, an outlet communicating with the interior of the enclosure and input flow path therebetween. The attic portion has an inlet communicating with the interior of the enclosure, an outlet communicating with the ambient air external of the generator structure and an exit flow path therebetween. An air flow generator draws ambient air through the inlet flow path in the eave portion of the roof structure into the interior of the enclosure to cool the engine and the alternator and urges air from the interior of the enclosure through the exit flow path in the attic portion and out of the generator structure.

摘要： A "hot start" method for arc welding includes selecting a first weld current, setting a time interval, striking an arc, flowing a second, higher weld current through the welding rod and then, after a brief time interval, reducing the current through the rod to the value of the first weld current. Also disclosed is a new arc welder stator having two groups of slots around a core. The group of larger slots contains the weld current windings and slots in the group of smaller slots contain windings for timing, gate voltage, battery charging, auxiliary power and the like. A new cooling apparatus for an arc welder has an air duct and a "double-bladed" fan for flowing air along several paths and cooling both the welder control section and the generating section. A new method for electronically controlling engine speed in an engine-driven arc welder is also disclosed. Such method includes manipulating a current-selecting device, contacting a work piece with a welding rod, accelerating the engine to an elevated speed and then either maintaining such speed or reducing it, depending upon the value of weld current selected.
