摘要： Method of and device for producing electric energy from a cyclic combustion process. The device includes two oppositely disposed aligned spark ignited internal combustion engine cylinders axially spaced from each other, means rigidly connecting the pistons so that they reciprocate in unison in their respective cylinders, and a reciprocable electrical linear generator-motor unit driven by said reciprocatory piston system. The generator-motor unit includes a very light coreless (ironless) coil rigidly attached to and reciprocatory with the piston system, the said coil reciprocating through a constant strength magnetic field. The beginning of the combustion process (or cycle) in each combustion chamber takes place at the lowest possible compression ratio sufficient for the initial ignition of the fuel-air mixture, the combustion process proceeding at a diminishing volume under the pressure from the compression- and combustion-forces of the opposite combustion chamber-piston system. The combustion process terminates after some extreme point at an expanding volume, whereby the resulting forces are used for compression in the opposite combustion chamber and there the cycle being repeated, which processes (cycles) are taking place under a positive feed-back relation. Because said feed-back relation is very pronounced, this results in a height velocity and a reciprocating rate of the connected piston system whereby there is induced an electromotive voltage in the coil.

摘要： A free piston gas generator assembly in which the scavenging efficiency of the power cylinder is increased, by interconnecting in series a plurality of three or more identical motor-compressor cylinders, by means of a piping system, into one engine assembly. Said interconnecting piping system constitutes a closed feedback or bounce energy transfer loop, by transferring the feedback or bounce energy of the up-stream motor-compressor cylinder to the down-steam motor-compressor cylinder in a continuous stepwise sequence. Consequently, the simultaneous outward and inward synchronized piston strokes of two motor-compressor cylinders in each working step, causes the pistons of the remaining motor-compressor cylinders in the assembly to be at rest in the outward dead points, where scavenging takes place. Hence, the number of motor-compressor cylinders interconnected by the feedback or bounce energy transfer loop and the cyclic frequency of the synchronized piston strokes, determines the scavenging time available for each of them, independently of the inertia of the respective piston mass.
摘要翻译：一种自由活塞气体发生器组件，通过将多个三个或更多相同的电动机 - 压缩机气缸通过管道系统串联连接到一个发动机组件中，增加动力缸的清除效率。所述互连管道系统通过将上游电动机 - 压缩机气缸的反馈或反弹能量以连续的逐步顺序传递到下蒸汽电动机 - 压缩机气缸来构成闭合的反馈或反弹能量传递回路。因此，在每个工作步骤中，两个电动机 - 压缩机气缸的同时向外和向内同步的活塞冲程使得组件中剩余的电动机 - 压缩机气缸的活塞在发生清扫的向外的死点中静止。因此，通过反馈或反弹能量传递回路相互连接的电动机 - 压缩机气缸的数量和同步的活塞冲程的循环频率，决定了它们中的每一个可用的清扫时间，而与各活塞质量块的惯性无关。

摘要： A piston engine employing a flywheel rotor, in lieu of a crankshaft, driven hydraulically by the piston. One end of a plunger is connected to the piston, the other end being slidably disposed in an hydraulic cylinder. In the combustion mode, fuel and oxygen are injected and spark ignited, both by the same variable speed D.C. speed control motor. The piston-driven plunger displaces hydraulic fluid in the cylinder through a high speed orifice to impinge against spaced cavity surfaces formed along the periphery of the flywheel rotor, thereby spinning the rotor. A slide valve is disposed in the orifice and is hydraulically connected to the cylinder so that pressure changes in the cylinder reciprocate the slide valve to provide momentary delay, during pressure build-up, and then release of the cylinder fluid, thereby increasing the fluid velocity. Hydraulic fluid is recirculated during an exhaust stroke wherein the piston is returned by injected air pressure.

摘要： Die vorliegende Erfindung betrifft ein Verfahren zum Betreiben eines Freikolbenlineargenerators (1) zur Erzeugung elektrischer Energie, wobei der Freikolbenlineargenerator (1) mindestens einen Lineargenerator (10) sowie mindestens eine Verbrennungseinheit (11) mit mindestens einer Brennkammer (110) aufweist und die Verbrennungseinheit (11) und der Lineargenerator (10) über zumindest eine Kolben-Läufer-Einheit (12) miteinander verkoppelt sind, die mindestens einen Kolben (120) umfasst, der einen Expansionshub von einem oberen Totpunkt (OT) zu einem unteren Totpunkt (UT) und einen Kompressionshub vom unteren Totpunkt (UT) zum oberen Totpunkt (OT) ausführt. Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, dass nach der Beschleunigung des mindestens einen Kolbens (120) die elektrische Energieentnahme durch den Lineargenerator (10) in der Weise geregelt oder gesteuert wird, dass hierdurch eine Regulierung der Geschwindigkeit des Kolbens (120) zwischen OT und UT erreicht wird. In einer vorteilhaften Ausführungsform der Erfindung wird der mindestens eine Kolben (120) nach der Zündung in der Brennkammer (11) zunächst bei OT maximal verzögert, bis die annähernd maximale Temperatur in der Brennkammer (110) erreicht ist, wobei nach Unterschreiten der angestrebten Geschwindigkeit (Verlassen des Regelbereichs) des Kolbens (120) eine finale Energieentnahme erfolgt, so dass der Kolben mittels Reluktanzkraft und optionaler Gasdruckfedern bis nahe UT durch den Lineargenerator (10) auf die Geschwindikgiet Null abgebremst wird und die Umkehr der Begegung (Rückfedrung) erfolgen kann. Die Beschleunigung von UT zu OT erfolgt vorzungswiese mittels Reluktanzkraft des Lineargenerators (10).

摘要： A free piston engine in which knocking of the engine is prevented by changing the return energy available to move the piston in its compression stroke and hence to vary the compression ratio. The apparatus includes a condition responsive means associated with possible knocking of the engine, which controls some controlling means for varying the return energy. Where the free piston engine employs a bounce chamber for controlling the return energy, the controlling means may be effective to change the pressure in this bounce chamber. Where the free piston engine has two power pistons acting alternately on a single assembly, the pressure ratio may be varied by controlling the amount of fuel admitted into one or more of the power cylinders. The apparatus also contemplates means for changing the return energy if a movable member driven by the piston moves too far with respect to an associated stationary member.

摘要： The disclosed engine comprises at least one cylinder inside which is moveably arranged a piston which may effect axial stroke motions within the cylinder and which is provided with cylindrical extensions which extend on both sides in the axial direction from the piston and presenting at least partially a diameter smaller than that of the piston, said extensions being partially guided in the axial bores. The cylinder presents combustion spaces which are formed of portions of inner surfaces of the cylinder wall and portions of the piston surfaces as well as of its extensions. Ports are provided in the longitudinal wall of the cylinder for air intake or air-fuel mixture as well as for the exhaust of burned gases, said intake and exhaust ports being respectively open or closed according to the axial position of the piston. Channels are provided inside the piston and its extensions to enable the controlled flow of fresh gases intended to the combustion, said channels communicating with borings provided in the surface of the envelope of the extensions. Through these borings, the channels may, for axial positions of the piston inside the cylinder which are substantially similar, communicate or not with the combustion spaces, the exhaust ports being also freed or closed by the piston.
