Reporters obtained the following quote from the background information supplied by the inventors: "The sweep core die device generally relates to injection dies and more specifically to two piece dies. More particularly, the invention has two movable and retractable arcuate cores that move simultaneously during casting.
"Dies produce various parts of many descriptions. Such parts function as individual machines or as a component in another machine. One machine is a motorcycle, having two wheels upon a frame with an engine and transmission and controls for them manipulated by the operator. The operator starts the motorcycle, operates the gears and the brakes, and steers the motorcycle as desired. The motorcycle moves under the power of its engine.
"Engines come in a plurality of designs. Yet all engines require fuel. Earlier engines utilized carburetors to blend fuel and air into a mixture. The mixture then entered the cylinders of the engine for combustion. Carburetors performed their blending with precise adjustments to select screws which regulated the flow of fuel and air through venture like passages within the carburetor. In time, the screws accumulate deposits from the fuel and vibration of the engine rattles the position of the screws. With the screws out of position or gummed up, the carburetor releases an altered fuel air mixture and the engine performs differently, usually poorly. The operator notices a decrease in performance when climbing hills or accelerating to pass a car. The operator may also detect an increase in fuel consumption.
"Noting the mechanical and fluid weaknesses of carburetors, scientists, engineers, and mechanics worked to develop a replacement, the fuel injector. A fuel injector delivers a precise amount of fuel through a shaped nozzle directly into the top of a cylinder. Each cylinder has its own injector, or throttle body. The injector disperses the fuel into the cylinder generally in mist form. The mist blends with air previously drawn into the cylinder and compressed by the piston into the head of the cylinder. Each throttle body has a sensor that detects the resulting fuel air mixture allowing for adjustment of the fuel into the next stroke of the piston in that cylinder. Each throttle body has electronic communication to a control module where a computer or microprocessor monitors and adjusts the fuel in real time."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "Generally, the sweep core die device has a cover insert and an ej insert that cooperatively engage leaving a void within them, a ram component that enters the void between the inserts, and two cores mutually connected to the ram for simultaneous movement. These components cooperate for causing simultaneous movement in several different axes within the voids. The cores have a generally mirror image shape and connect to one end of a mount. The other end of the mount pivotally connects to the ej insert. A shaft pivotally connects to each mount and to a cylinder clamp outwardly from the two inserts. The cylinder clamp moves inwardly and outwardly from the two inserts and moves the shafts inwardly and outwardly thus rotating the cores inwardly and outwardly through the void. The cores have the internal shape of the passage through each horn of a finished injector. The cores produce passages that allow fuel to attain laminar flow conditions within the throttle body.
"There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and that the present contribution to the art may be better appreciated. The present invention also includes two mirror image sweep reliefs in the ej insert upon which the cores traverse, ball joint connections of the shaft to the mounts and to the cylinder clamp, and clamp connection of the ball joint and core to the mount. Additional features of the invention will be described hereinafter and which will form the subject matter of the claims attached.
"Numerous objects, features and advantages of the present invention will be readily apparent to those of ordinary skill in the art upon a reading of the following detailed description of the presently preferred, but nonetheless illustrative, embodiment of the present invention when taken in conjunction with the accompanying drawings. Before explaining the current embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
"One object of the present invention is to provide a sweep core die device that produces two passages in an injector that achieve laminar fuel flow.
"Another object is to provide such a sweep core die device that forms passages simultaneously.
"Another object is to provide such a sweep core die device that sweeps through any angle whether compound or straight.
"Another object is to provide such a sweep core die device that allows for alteration of passage geometry by replacement of cores.
"Another object is to provide such a sweep core die device that casts injectors utilizing metals and polymers as materials of the cast injector.
"Another object is to provide such a sweep core die device that operates two mirror image portions simultaneously.
"Another object is to provide such a sweep core die device that can be easily and efficiently manufactured and marketed to the die makers and molders.
"These together with other objects of the invention, along with the various features of novelty that characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and the specific objects attained by its uses, reference should be had to the accompanying drawings and descriptive matter in which there is illustrated a preferred embodiment of the invention.
