摘要： The invention concerns a rotary piston engine (1) that includes at least two straight circular cylinders (7), which are parallel with each other and connected to each other along a longitudinal cylinder jacket opening. In the cylinders (7) pistons (2, 3) are arranged rotably journaled in the cylinders (7). A sealing rod (6) is arranged in said cylinder jacket opening and is displaceable across the pistons (2, 3) in sealing contact with mantle surfaces of these. The pistons (2, 3) have central circular cylindrical parts, which have smaller diameters than the cylinders (7) and two opposite protruding wings each, that radially outward define exterior piston mantle surfaces, substantially having the same diameter as the cylinders (7), and are arranged to slide closely along jackets (8) of the cylinders (7). In the cylinder jackets (8) there are pairs of exhaust and intake openings (10-13), which are opened and closed by flap valves (9a-9d) and lead to different working chambers. In a certain rotational position of the pistons (2, 3) together with the sealing rod (6) and an opposite cylinder jacket part (8) they form a combustion chamber in said cylinder jacket opening.

摘要： The present invention relates to positive displacement pneumatic machines, and more particularly the present invention relates to internal combustion engines. A rotor-piston internal combustion engine of the invention comprises a body comprising a main cylindrical cavity in which a rotor-piston is concentrically mounted, the rotor-piston comprising radial protrusions and radial recesses on the peripheral surface thereof, the radial protrusions and radial recesses forming, in conjunction with substantially cylindrical inner walls of the body, a plurality of closed segmental cavities; combustion chambers comprising nozzles to inject fuel and spark plugs; three-blade separating rotors installed in the combustion chambers with the possibility of discrete turn through 120° with stops; and gas distribution devices comprising inlet channels and outlet channels. The advantages of a rotor-piston internal combustion engine of the invention are high smoothness of the torque, division of the segmental cavities of the rotor-piston without employing separating vanes and reduction of gas-dynamic losses.

摘要： In a rotary machine (10) including a rotor (50) and a bore surface (37) with which the rotor interacts to cyclically define a fluid chamber (60) during rotation, a variable member (1002) defining part of the bore surface is movable relative to the rotor by means responsive to desired operating conditions to vary the point where the rotor and surface begin or end a sealed relationship. In a machine including a seal (82) on the rotor movable with respect thereto toward a complementary surface to seal with it, the sealing point progressing about the surface, a means of restraint (1102) is responsive to rotor speed to increase restraint on relative motion of the seal toward the complementary surface to enable decrease or elimination of direct pressure contact between the seal and surface upon increased speed. In a machine also comprising stationary surfaces with which the rotor interacts, a seal seals with a complementary surface of the chamber during rotor motion, the seal comprised of at least one member on the rotor defining a sealing surface in face-to-face relationship with the complementary surface, means (1202) between the member and rotor bias the seal toward the complementary surface, the biasing force applied varying with rotor speed. A tracking sealing system (figs. 1e and 12b-e) for retarding leakage from the fluid chamber is also described.

摘要： A rotary engine includes a housing body having a first rotation chamber and a second rotation chamber. A first rotary body is arranged within the first rotation chamber, and a second rotary body is arranged within the second rotation chamber. A boundary surface of the first rotation chamber has a variable distance from an opposite surface of the first rotary body. A pair of valve flaps having a first valve flap and a second valve flap is arranged on the first rotary body. Upon rotation of the first rotary body, the valve flaps are in engagement with the boundary surface of the first rotation chamber and are rotated in mutually opposite directions with regard to the first rotary body so as to form two mutually demarcated working chambers within the first rotation chamber.

摘要： A rotary machine in which plural, cylindrical rotors are provided for rotation within partially overlapping cylindrical bores, formed within a machine housing. The rotors are eccentrically mounted for synchronized, same directional rotation, within their respective bores, and each is arranged to alternately provide intake and exhaustion of working gaseous fluids, such that each rotor is continually either admitting or exhausting a working gas. The machine is constructed such that the rotors are cylindrical, each being of internally balanced form. The rotors do not touch each other or any portion of the machine casing at any time, while being positioned so as to define minimal gaps therebetween. A high rotational speed may be developed, thereby obviating the need for seals entirely, and thus further increasing the available speed, and thus the work efficiency of the machine.

摘要： A rotary piston machine comprises, arranged inside the gas-tight inner chamber (22) of a housing (24), a piston assembly (20) composed of at least three separate pistons (26) that are of identical design in the form of rectilinear prisms having front faces limited by several arcs of circle (28, 30). Said pistons are each fixedly secured to and turn in the same direction (36) as a shaft (34) rotatively mounted in the housing, extending through the geometric central axis and the rotation of which is synchronised by means of a gear, have flush front faces and laterally limit the inner working space (38) with their curved circumferences, leaving a gap (S) between adjacent rotary pistons (26). Sealing elements (42) mounted in each gap (S) have two parallel sealing bars (44, 46) which have a cross-section that is wider than the gap (S) and are mutually linked by a connecting piece (48) narrower than the gap (S), and have a length that substantially corresponds to the length of the rotary pistons (26).

摘要： A rotary engine includes a housing and elliptical rotors mounted to rotor shafts for rotation within a chamber of the housing. A valve disk mounted to a rotor shaft includes a port passing between first and second sides. A valve plate includes a bore defining a cylindrical sidewall for rotationally receiving the valve disk. The valve disk includes a groove disposed in a wall, and includes a ring member disposed in the groove that contacts the sidewall of the bore when the valve disk is disposed in the bore. The apparatus may include multiple valve disks disposed in separate bores to operate as exhaust or intake valves. Circumferential channels may be included in the bore sidewalls within which the ring members are disposed.
