Abstract:
The invention relates to a rotary piston machine which operates as a pump, a compressor, or a motor and which has a rotor (2) and a counter rotor (4), said counter rotor (4) being disposed opposite the rotor (2). The rotor (2) has a first end surface (6) with a first toothing system (8). The counter rotor (4) has a second end surface (14) with a second toothing system (16). The first (8) and the second toothing system (16) are each made of at least one tooth (10, 18) and a tooth space (12, 20). The toothing systems (8, 16) are in engagement with each other such that working chambers (24) are formed by means of the meshing of the teeth (10) of the first toothing system (8) and the teeth (18) of the second toothing system (16), wherein volumes that are formed by the working chambers (24) are changed by means of the meshing of the teeth (10, 18). The rotor (2) has a first rotational axis (I). The counter rotor (4) has a second rotational axis (II). The first rotational axis (I) and the second rotational axis (II) enclose an angle (phi) that is not equal to 0 degrees. According to the invention, the rotor (2) has a first spherical ring-shaped inner wall (26) and the counter rotor (4) has a first spherical ring-shaped outer contour (28) that is designed in a complementary manner with respect to the first spherical ring-shaped inner wall (26) of the rotor (2).
Abstract:
The workspace with rotary moving piston has the advantages of easier sealing of the double flank piston (4), which between the dead centers performs the oscillating movement while rotating around one sealing line and slides with its cylindrical surface (51) on the cylindrical surface of adjacent chambers (21a, 22b) with the same radius R. The workspace has the shape of a regular tricuspid star (1), Every two adjacent chambers (3N, 3N+1) have a common center (S) of the opposite cylindrical surfaces (2Na, 2N +1 b) with a radius R. The connecting line of adjacent chambers (31, 32), that is, the intersection of the cylindrical surfaces (21b, 22a), corresponds to the common center (S) of the opposite cylindrical surfaces (21a, 22b). The piston (4) performs an oscillating, rotational movement with gradually changing center of rotation, its motion is transferred to the protruding shaft (7). The workspace can be part of a combustion engine or pump, a blower, a compressor and the like.

Die erste (8) und die zweite Verzahnung (16) sind je aus zumindest einem Zahn (10, 18) und einer Zahnlücke (12, 20) gebildet. Die Verzahnungen (8, 16) stehen miteinander derart in Eingriff, dass durch Kämmen der Zähne (10) der ersten Verzahnung (8) und der Zähne (18) der zweiten Verzahnung (16) Arbeitsräume (24) ausgebildet werden, wobei durch die Arbeitsräume (24) gebildete Volumina durch das Kämmen der Zähne (10, 18) verändert werden. Der Rotor (2) weist eine erste Drehachse (I) auf. Der Gegenrotor (4) weist eine zweite Drehachse (II) auf. Die erste Drehachse (I) und die zweite Drehachse (II) schließen einen Winkel (φ) ein, der ungleich 0 Grad ist. Erfindungsgemäß weist der Rotor (2) eine erste kugelringförmige Innenwandung (26) und der Gegenrotor (4) eine erste kugelringförmige Außenkontur (28) auf, die komplementär zu der ersten kugelringförmigen Innenwandung (26) des Rotors (2) ausgebildet ist.
Abstract:
A thermal design and method of operation of a rotary internal combustion engine having at least one housing (12), a rotor (14) rotating within the housing, and a mechanism for combusting a mixture of fuel, air and steam supplied into the housing to drive the rotor, in which the temperature of the inner walls of the combustion region which are in contact with combusting gases attains 700 degrees C, and in which the temperature of the combusting gases does not exceeds 1800 degrees C. The thermal design includes: lining of the surface of the combustion zone with heat resistive material such as a refractory metal; the use of material with low heat conductivity such as iron for the construction of the body of the engine in order to minimize heat loses by heat transfer to ambient; and the effective cooling of the body of the engine with boiling heat transfer by water which is circulated in cooling channels (53, 55, 56) passing throughout the engine's structure.

Abstract:
A gerotor mechanism having one or more "work gerotor sets" that operate on the working fluid, where the inner and outer gerotors approach each other closely, but do not make mechanical contact; b) one or more "sync gerotor sets" which using direct lubricated or non-lubricated contact between the inner and outer gerotors to transmit mechanical drive and to keep the assembly of gerotor sets synchronized and co- rotating, and, c) one or more mounting members (e.g. central common shaft, "CoRotor bearings", etc.) to provide nominally independent rotation of all rotating components of the work gerotor sets; to transmit forces between work and synch gerotor sets; and to act as a mechanical seal that keeps separate the working fluid of the work gerotor set from the working fluid of the sync gerotor set.
