The invention concerns a method for making a two-stroke engine, capable of running exclusively on gas, or a back draught-free engine by not using fixed connecting rods but rather standard rods, thereby enabling to keep a small-size engine.

The invention aims at generalizing in the form of a single traction engine and hence in the form of a single invention, any traction engine with closed compression chambers. It will be shown that, both in their shapes and in their support methods, prior art traction engines, as well as those already disclosed by the present applicants can all be included in unified manner, to be then physically represented in several embodiments whereof the construction and combination principles will be here disclosed. Among these machines, are included for example retro-rotary traction engines, namely triangular motors, polyturbines, differential semi-turbines, machines with rotor cylinder, standard, Slinky, machines with peripheral cylinders and several others. Therefore, the invention aims at demonstrating in unified manner the main types of machines, mechanical types of support of compression parts, types of shapes of compression parts. Finally some particular features will be defined, such as the use of multiple-cam and interlocked eccentric gear assemblies, as well as some specific types of techniques for balancing the support and certain types of gas management enabled by said types of machines.

An apparatus and method is provided for a dual compression and dual expansion internal combustion engine that is compact, efficient, and has low combustion noise and emissions. The subject engine includes a low pressure piston assembly reciprocally disposed in an operating chamber defined in a housing. A pair of opposed high pressure piston assemblies are directly mounted on a pair of geared together, counter rotating, crankshafts and reciprocally disposed in bores of the low pressure piston assembly. The disposition of the second and third piston assemblies within their respective bores defines a combustion chamber. An intake chamber for compression of inducted air and an exhaust chamber for expansion of exhaust gas are defined in the operating chamber between the low pressure piston assembly and the housing. Air moves from the intake chamber to the exhaust chamber, but in the process the air compressed, mixed with fuel, and combusted. The resulting gas is expanded in the combustion space between the high pressure piston assemblies. A complete cycle from start of air entry into the intake chamber to the exit of the exhaust gas of the same charge from the exhaust chamber takes approximately 900 degrees of rotation of the crankshafts during which the intake chamber, the combustion chamber, and the exhaust chamber each undergoes five "strokes". Thus, the disclosed engine is compact, efficient, and has less combustion noise, and low emissions.

A compact lightweight engine (20) or pump is constructed having a H-shaped piston (56), usually double acting. Each end of the piston (56) has extending surfaces (70, 72 and 74, 76) which form two moving sidewalls which act with two case sidewalls (58, 60) and a block-shaped head (114, 116) protrusion to define a working chamber (78, 80) with the appropriate top surface of the piston (62, 63) which moves to extract or add energy to the working chamber (78, 80). Energy is transferred between the piston (56) and a crankshaft (25) by means of a slide block (50) on the crankshaft and the inner surfaces of a pair of parallel walls forming the center of the «H» of the piston, whose opposite surfaces form the piston top surfaces. Through the use of suitable cams and valves, 4-cycle, 2-cylinder equivalent engines can be produced. With suitable porting, baffles, and/or auxiliary compression means, 2-cycle engines can also be produced as well as air pumps. The planar walls of the devices maximize displacement while the planar design reduces mechanical stress allowing coatings of heat resistant materials such as ceramic for thermal protection rather than extensive cooling systems.

@ Un moteur à carburation volumétrique avec deux pistons (2-7) pour chaque cylindre et en culasse des soupapes (14) à glissement; les deux pistons (2-7) à l'intérieur du cylindre sont intubés l'un (7) dans l'autre (2), et le piston (7) interne, qui se déplace dans le même sens que le piston (2) externe, a une course double de celle de celui-ci (7) et leur PMS (piont mort supérieur) coincident. Dans les phases d'aspiration et de détente après la combustion, la cylindrée disponible est supérieure a celle d'un cylindre similaire à piston unique et ceci permet, respectivement, d'utiliser une charge majeure pour un rapport de compression supérieur et de recueillir une plus grande force de détente des produits de la combustion.

The invention relates to a dual piston engine comprising two pistons (1, 3) which can be displaced in relation to each other,characterized in that the outer diameter of the one piston (1) corresponds approximately to the inner diameter of the combustion chamber, wherein the one piston (1) is displaceably arranged in the combustion chamber and comprises on the side facing away from the combustion chamber a receptacle for the other piston (3). The other piston (3) is displaceably arranged in the receptacle of the one piston (1) and is connected to a shaft via a connecting rod (4), the one piston (1) comprising on the front face facing away from the other piston (3) an opening that connects the receptacle to the combustion chamber above the one piston (1) and can be closed by the other piston (3).

An internal combustion engine (1010 or 2000) is provided. The internal combustion engine includes a housing (1013 or 1068) and a piston assembly (6, 1012, and 2038) disposed on the housing: The piston assembly is substantially stationary relative to the housing. A cylinder (1, 1014, and 2040) is movably disposed within the housing. A combustion chamber (20, 1033, and 2064) is disposed between the piston assembly and the cylinder.

Die Konstruktion eines 3-Kammer-Zylinders ermöglicht die Erweiterung der nutzbaren Kolbenfläche durch Integration einer zweiten Vorlaufkammer in den Zylinder. Abbildung Fig. 5 stellt einen Längsschnitt durch den 3-Kammer-Zylinder dar, der durch die Öffnungen 51 zu Kammer a und 58 zu Kammer b mit Flüssigkeit oder Gas angetrieben wird = Vorlauf. Durch die Öffnungen 59 und 55 entweicht die Flüssigkeit oder das Gas aus Kammer c = Rücklauf. Gleichung: Durch die Kolbenflächen 52 und 53 in den Kammern a und b wird die Preßkraft des 3-Kammer-Zylinders bestimmt. Gleichzeitig sind die Öffnungen 59 und 55 geöffnet. Durch die Kolbenflächen 52 und 53 aus der Sicht der Kammer c wird die Zugkraft des 3-Kammer-Zylinders bestimmt. Gleichzeitig sind die Öffnungen 51 und 58 geöffnet. Wenn die Zugkraft und die Preßkraft gleich groß sein sollen, dann muß die Flüssigkeit oder das Gas mit dem doppelten Druck in die Kammer c gepumpt werden, da dieser Arbeitshub nur aus einer Kammer = c erfolgt und nicht, wie bei der Preßkraft, aus zwei Kammern. Abbildung Fig. 6 zeigt den Längsschnitt des 3-Kammer-Zylinders in eingefahrenem und Abbildung Fig. 7 in ausgefahrenem Zustand.
