Abstract:
A reciprocating part free kinematic apparatus, designed for transforming the volume variations of a plurality of chambers into a rotary motion of an axis, is characterized in that all the mechanism for performing this function is housed in a cylindric cavity coaxial with the driving axis, between the cylindric cavity, a smaller diameter inner coaxial cylinder and two discs perpendicular to the axis, being defined a toroidal cavity in which are housed rotary pistons, each longitudinally traversed by an axis and having a cross-section schematically in the shape of a circular sector, said rotary pistons rotating so as to cause the cavities defined therebetween, also of a substantially circular sector shape cross section, to cyclically change their volumes. This variation, controlled by a mechanism including a cam, the axes passing through the pistons and suitably arranged connecting rods, provides a fluid working cycle causing the driving shaft to rotate through a mechanism including a connecting rod and related crank system. Accordingly, the disclosed kinematic motion apparatus can be used both for transforming the expansion of the pressurized fluid into a mechanical work available on an axis, and to transform the mechanical work into a potential energy, by transforming it to a fluid through a compression operation.
Abstract:
The invention relates to a fluid pump with a rotation- symmetrical pump housing, a rotatably drivable shaft extending coaxially thereto, at least three blades extending radially from the shaft, at least one supply opening arranged in a pump housing wall and at least one discharge opening arranged in a pump housing wall, wherein the supply opening extends over a first arcuate part and the discharge opening extends over a second arcuate part, wherein the second arcuate part lies outside the first arcuate part, and blade displacing means are arranged for the purpose of increasing the distance between adjacent blades at the position of the supply opening and for reducing the distance between adjacent blades at the position of the discharge opening. This pump is a displacement pump. Fluid is here suctioned into a space between two blades because the volume between these blades is increased. Fluid is forced out when the space between the blades is reduced.

Abstract:
Beide Kolben (1) haben die gleiche Form und befinden sich in einem zylindrischen Gehäuse (2), dass eine Ansaugöffnung und eine Auslassöffnung für Gase besitzt. Die Kolben teilen den Zylindrischen Raum in vier Arbeitskammern auf. In Abhängigkeit davon, ob der Motor als Otto- oder Diesel-Motor arbeitet, befindet sich im zylindrischen Gehäuse eine Zündkerze oder eine Einspritzdüse für Kraftstoff (3). Die abgedichteten Kolben bewegen sich um eine gemeinsame Achse in die gleiche Richtung. Die Kolben sind unabhängig voneinander über gleiche, aber umgekehrte Übertragungssysteme des Antriebs (5), mit der Kurbelwelle (4) verbunden. Der Motor wird durch einen Anlasser über ein Schwungrad (6), dass an der Kurbelwelle angebracht ist, gestartet. Über Antriebssysteme erzwingt die Kurbelwelle eine Verschiebung des Kolbens im Gehäuse. Gleichzeitig wird der zweite Kolben blockiert. Der Motor startet. Die Kolben bewegen sich zyklisch abwechselnd umeine halbe Umdrehung. Jede Bewegung der Kolben um eine halbe Umdrehung verursacht vier Volumenänderungen, was den vier Takten des Viertakt-Verbrennungsmotors entspricht, das bedeutet, dass in jedem Moment der Verschiebung der Kolben folgende Takte (Hübe) ausgeführt werden : Ansaugtakt, Verdichtungstakt, Arbeitstakt und Ausstoßtakt. Das Antriebssystem überträgt die Leistung vom Kolben auf die Kurbelwelle. In Abhängigkeit von der Stellung der Excenterräder der Kurbelwelle, blockiert das System bei der Zündung den Kolben für längere oder kürzere Zeit. Alle Ansaug-, Verdichtungs-, Arbeits- Arbeits- und Ausstoßtakte passieren immer in der gleichen Stellung des Motors. Bei jeder Umdrehung der beiden Kolben im Motor erfolgen 16 Takte (Hübe), das heißt : 4 Ansaugtakte, 4 Verdichtungstakte, 4 Arbeitstakte, 4 Ausstoßtakte. Gleichzeitig macht die Kurbelwelle zwei volle Umdrehungen. Aus solchen Einheiten kann man leicht einen Reihenmotor bauen. Um einen Turboeffekt zu erzielen, muss man bei einer Einheit des Reihenmotors das Motorgehäuse so verändern, dass diese Einheit im System mit zwei Ansaugtakten und zwei Verdichtertakten gleichzeitig arbeitet. So übernimmt dieses Glied des Motors die Funktion des Rotationskompressors.
Abstract:
Methods of sealing a planetary rotor engine (10), and the resulting seals, are described which improve the engine's efficiency and solves each of three main problem areas. A first method and resulting dynamic seal for sealing the rotor face surfaces as they translate across one another to constantly reform the contact between each other includes the key step of moving the shaft centerlines of each of the rotors (16, 18, 20, 22), thereby radially positioning the rotors along diametric axes at positions which compensate for varying thermodynamic conditions (e.g. thermal expansion or contraction of rotor material). A second method and resulting dynamic seal for effectively minimizing leakage between the end space formed between the rotor end and the case includes the key step of introducing a surface depression (46) of any shape on one, or both of the rotor end (36, 38, 40, 42) and opposing casing (13, 14), thereby eliminating the need for a frictional seal and, in essence forming a pressure wave plug. A third method and resulting dynamic seal for sealing around the rotor centershaft takes advantage of and is responsive to the changes in pressure and partial vacuum pulses during the operation cycles of the engine. An annular pivot and lever seal (44) comprises a specially configured annulus for surrounding the centershaft having, generally described, a pivotal H-shaped cross section configuration adapted to seesaw in correspondence with positive and negative pressure changes over a single pressure wave to seal against the adjacent inner wall of the rotor case.
