Patent Application
20160281599
The disclosure relates to engine devices and more particularly pertains to a new engine device for providing opposed pistons in linear alignment for compressing explosive gases within an engine block cylinder.
An embodiment of the disclosure meets the needs presented above by generally comprising an engine block having a plurality of cylinders having linearly aligned open ends. Each of a pair of piston crankshafts is positioned on a respective side of the engine block in alignment with the cylinders. Pistons are positioned in pairs within each cylinder and coupled to an associated one of the piston crankshafts such that rotation of the piston crankshafts moves the pistons within the associated cylinder. Each piston crankshaft is rotated by an associated gear. The gears are geared together coordinating the piston crankshafts to alternately urge oppositely positioned pistons together and apart within the associated cylinders as the piston crankshafts rotate.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each of a plurality of intake conduits 30 extends through the engine block 12 and is in environmental communication with an associated one of the cylinders 14 in a conventional manner. Each of a plurality of intake valves 32 is positioned in an associated one of the intake conduits 30 in a conventional manner. Each intake valve 32 is transversely oriented relative to the associated cylinder 14. Each of the intake valves 32 is coupled to an intake camshaft 34. The intake camshaft 34 is rotated by rotation of the gears 26 wherein each intake valve 32 moves within the associated intake conduit 30 for allowing or urging a fuel 36 into the associated cylinder 14 in a conventional manner when the fuel 36 after the fuel 36 is introduced into the associated intake conduit 30.
Each of a plurality of exhaust conduits 38 extends through the engine block 12 and is in environmental communication with an associated one of the cylinders 14. Each of a plurality of exhaust valves 40 is positioned in an associated one of the exhaust conduits 38. Each intake valve 32 is linearly aligned with an associated one of the exhaust valves 40. Each of the exhaust valves 40 is coupled to an exhaust camshaft 42. The exhaust camshaft 42 is rotated by rotation of the gears 26 similarly to the rotation of the intake camshaft 34. Each exhaust valve 40 moves within the associated exhaust conduit 38 such that each exhaust valve 40 is configured for removal of combusted fuel out of the associated cylinder 14 in a conventional manner after the fuel 36 is ignited within the associated cylinder 14. Each cylinder 14 is structured to include a spark plug aperture 46 wherein each cylinder 14 is configured for ignition of the fuel 36 within each cylinder 14 by a respective spark plug 48 coupled to the engine block 12 adjacent to the spark plug aperture 46 in each cylinder 14. Each spark plug aperture 46 is positioned proximate the exhaust conduit 38 in the associated cylinder 14. The movement of the pistons 22, compression of the fuel 36, intake of the fuel 36 and exhaust of the combusted fuel is generally conventional in function. Thus, one skilled in the art would be able to structure the engine block 12 to provide the above described positional relationships and functions.
In use, each cylinder 14 provides for alternating separation and moving together of the piston pairs 24. The fuel 36 is introduced into each cylinder 14 by movement of the piston pairs 24 in a separating motion while the associated intake valve 32 is open. The piston pair 24 compresses and the spark plug 48 is fired to combust the fuel 36 driving for separation of the piston pair 24. Compression by the piston pair 24 immediately after combustion is coordinated with opening of the exhaust valve 40 prior to opening of the intake valve 32 and introduction of new fuel into the cylinder 14. The device 10 may be used to rotate a driveshaft in conventional fashion to produce work.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
