摘要： A rotary piston engine (10) is described, with a housing (12), with two shafts (18, 20) running on bearings therein and coupled by a wheel gearing, with the shafts bearing two rotary pistons (28, 30) that can be put into counter-rotational motion in the housing by admission of a compressed medium, which motion can be used for the drive via one of the shafts. The two rotary pistons (28, 30) contact each other and the housing wall (32) under elastic pressure and like said housing wall they comprise extruded sections. The compressed air intake and outlet are arranged and designed in such a manner that as small a dead space as possible is formed. By means of this structure leakage losses are avoided, so that the engine has a good efficiency and can be used in particular as a swivel actuator with an actuating stroke of 360°.

摘要： Eine Rotationskolbenmaschine mit wenigen, plattenförmigen Bauteilen hat innerhalb des Gehäuses (G) einen bevorzugt zwischen zwei Verdichterblöcken gekapselten Motorblock (M, 1). Auf Wellen (54, 55) gelagerte gleichartige Flügelläufer (4, 5) kämmen mit dazu achsparallelen Drehkörpern (6, 21) berührungslos derart, daß einander diametral gegenüberliegende Arbeitsräume (7; 8) sowie Ein- und Auslässe (12; 15, 16) pro Umlauf z.B. zweimal von den Flügeln (18; 19) überstrichen werden; dann sind bei faktischer Hubraum-Verdoppelung die Brennraum-Kaltflächen anteilig halbiert. sowie die vier Ein- und Auslaßöffnungen ebenfalls faktisch verdoppelt und so die Strömungsgeschwindigkeiten entsprechend gesenkt. Kurze, breite Verbindungswege (10, 20) bewirken guten Gasaustausch mit mäßig hoher Strömungsgeschwindigkeit. Während jeder Motorwellen-Umdrehung erfolgen zwei symmetrisch-gegenüberliegende Verbrennungshübe (= vier Arbeitshübe), somit je vier Auspuff-, Spül-, Ansaug- und Verdichtungshübe. Die Konstruktion erlaubt Vollkeramik- und Typenvielfalt bei hohem Wirkungsgrad.
摘要翻译：具有很少板形部件的旋转活塞式发动机在壳体（G）内部具有优选地封装在两个压缩机块之间的发动机缸体（M，1）。支撑在轴（54,55）上的相似的叶片转子（4,5）与轴向平行的旋转体（6,21）啮合，使得叶片（18; 19）在直径相对的工作室（7 ; 8）和入口和出口（12; 15,16），例如每转两次; 在这样做时，燃烧室冷表面的比例减半，而实际位移加倍，并且四个入口和出口实际上也加倍，从而相应地降低了流速。短的，宽的连接路径（10,20）在适度高的流速下导致良好的排气和再填充。在发动机轴的每次旋转期间，发生两个对称的相对的燃烧冲程（=四个工作冲程），因此发生四个排气，扫气，进气和压缩冲程。该设计允许完全陶瓷结构和各种类型的高效率。

摘要： Internal combustion engine includes a rotary oxidizing gas compressor, a constant volume combustion chamber with pneumatically controlled intake and exhaust valves and a fuel injector, and a rotary combustion gas expander. Each of the rotary compressor and rotary expander has a pair of tangential rotors dependently rotatable in a housing, one rotor having a vane and the other a notch for allowing passage of the vane, to form a fluid tight segmented annular region through which the vane moves. The respective one of the intake valve and the exhaust valve admits a mass of high pressure compressible fluid to the region through a triangular port for expansion or from the region after compression, the mass of fluid being confined in a part of the region between the vane and the surface of the notched rotor and changing in pressure because of the change in arcuate length and volume of the confined part. The respective pairs of rotors are included on the same respective shafts. Two vanes may be included on the one rotor and two notches on the other. Two vaned rotors may cooperate with one notched rotor, the vaned rotors being on separate shafts.

摘要： A kind of gear is provided with shorter teeth, transition teeth and at least one longer tooth. The cross-section of the longer tooth is of a hawk beak shape, and the profile of the longer tooth is smoothly connected in series by a convex section, a tip section, a concave section, and a leading section. The two sides of the longer tooth are each provided with a transition tooth which neighbors a shorter tooth on the opposite side of the longer tooth. The pair of engaging gears according to this invention has advantages of reducing the fluid leakage, canceling the inertia of the rotors, and minimizing the vibration and noise. This invention also discloses a fluid machine for conveying, compressing or expanding liquid or gaseous fluids, which includes a casing comprising a housing, an upper end cover and a lower end cover. At least one pair of engaging gears which includes one driving rotor according to this invention and one driven rotor according to this invention is accommodated in the housing. As a result, the leakage between the rotors can be reduced, therefore the compression ratio can be improved. In addition, over compression and under compression can be avoided in operation.
