    摘要: A first rotor configured to rotate adjacent to a second rotor is disclosed. The second rotor includes a circular main body with a first axis of rotation and a vane extending radially from the main body. The first rotor includes a first curved surface that corresponds to a curve swept at a constant radius about a second axis of rotation, a second curved surface that corresponds to a curve swept by a leading edge of the vane when the second rotor is simultaneously rotated about the first axis of rotation and the second axis of rotation, a third curved surface that corresponds to a curve swept by a trailing edge of the vane when the second rotor is simultaneously rotated about the first axis of rotation and the second axis of rotation, and a vane-receiving groove disposed between the second curved surface and the third curved surface.

    摘要: The invention is a rotary engine comprised of at least one and usually a plurality of independent partial engines. Two different processes can be carried out in each independent partial engine both of which are used to operate the engines. The processes of the invention are basically two different and separate closed cycle processes that can both operate within the same geometric confinement, i.e. the same expansion chamber or expansion chambers, at the same time. The primary process performs the main function of converting heat to kinetic energy and is necessary in all engines of the invention. It is a unique process that uses the expansion of gases and also the contraction of the condensing gases after their expansion. The secondary process is needed for start-up and to provide additional power in case the engine might go into a stall. In most engines of the invention both processes are needed to operate the engine.

    摘要: Various apparatuses are provided for planetary rotor machines including a plurality of helical rotors and a corresponding manifold. In one example, the manifold includes a head plate to which each of the rotors is rotatably mounted. The head plate includes a fluid flow opening having a center coaxial with a central axis of the machine. The fluid flow opening comprises a plurality of ports that each correspond to one of the rotors. Each of the ports comprises an inwardly curving inner side extending between a starting point and an ending point, a first lateral arcuate side that forms with the inner side a first pointed notch in the head plate, and a second lateral arcuate side that forms with the inner side a second pointed notch in the head plate. The second lateral arcuate side is a mirror image of the first lateral arcuate side. The manifold substantially prevents fluid from bypassing a cavity created by the rotors of the machine.

    摘要: The gear machine according to the invention includes a driving gear wheel (1) and a driven gear wheel (2) having meshing gear teeth (21,22) having a special novel shape designed to provide improved gear wheel kinematics as well as minimal volume flow rate fluctuations. A correction of the gear teeth side geometry is performed by local limited adjustment of the basic transmission function i for eliminating volume flow rate fluctuations so that a discontinuity-free transmission is attained which results in an improved motion of the driven gear wheel with reduced acceleration changes. In order to accomplish this improvement in kinematics, the shape of the flanks or sides (25,26) of the engaging or meshing gear teeth (21,22) is such that the transmission function i depends on a spacing (g.sub..alpha.y) of an instantaneous contact point (Y) from a pitch point (C) of the two gear wheels (1,2) and changes continuously with a continuous derivative with a zero derivative at a gear tooth engagement change point occurring at a maximum value of that spacing (g.sub..alpha.y).

    摘要: An internal combustion engine comprises a toroidal combustion chamber housing within which slides at least one piston. The combustion chamber housing has a circumferential longitudinal slot sealed by a ring seal to which the pistons are rigidly attached. A mechanism is provided for reversibly creating one or more transverse seals within the combustion chamber housing. The space between the transverse seals constitutes one or more combustion chambers. The simplest embodiment of the engine has one combustion chamber and one piston. The combustion chamber is operationally divided by the piston into two regions. The space between the transverse seal and a trailing surface of the piston defines a combustion region. The space between the transverse seal and a leading surface of the piston defines an exhaust region. In each power cycle of the engine, compressed air, fuel and steam are injected into the combustion region and ignited. The resulting hot combustion gases drive the piston around the circular path defined by the toroidal housing, with power being transferred from the piston and the ring seal via a suitable linkage to a central power shaft. Meanwhile, the leading surface of the piston pushes the combustion gases of the previous cycle out of the combustion chamber housing, preferably into a similar toroidal expansion chamber housing where further expansion of the combustion gases drives a second piston that is similarly linked to the power shaft. The scope of the invention also includes a protocol for injecting air, fuel and steam into the combustion housing.

    摘要: The invention relates to an internal combustion engine having separate rotary compression and expansion sections and a combustion chamber (16) having valved inlet and outlet ports (21,22) communicating with the compression and expansion chambers respectively. Each section is a rotary device comprising a first rotor (14b) rotatable about a first axis (11) and having at its periphery a recess (R) bounded by a curved surface; and a second rotor (14a) counter-rotatable to the first rotor (14b) about a second axis (10), parallel to the first axis (11), and having a radial lobe (P) bounded by a curved surface, the rotors intermeshing whereby, on rotation thereof, a transient chamber of progressively increasing (expansion section) or decreasing (compression section) volume is defined between them. The rotors (14a,14b) are rotatable at a relative speed ratio, preferably 2:3, and are contoured such that during passage of the lobe (P) through the recess (R), the recess surface is continuously swept, by both a tip (17) of the lobe (P) and a movable location (18) on the lobe (P) which progresses along the lobe surface, to define the transient chamber.

    摘要: An external shaft rotary piston machine wherein pistons of a piston rotor run in engagement with a cavity of a circular cylindrical sealing rotor during a particular relative rotational position of the rotors, the cavity being substantially larger than necessary for passage of the pistons in order to avoid flow losses due to seal wedging flow and compression. In order to avoid overflow from the high pressure side to the low pressure side of the machine through the sealing rotor while the pistons move in the sealing rotor through the space defined by the cavity, a sealing effect is created by a leading edge and a trailing edge portion of the opening of the cavity of the sealing rotor moving along a leading and a trailing side surface of the pistons. This is effected kinematically due to the fact that the trailing edge of the cavity opening is displaced radially inwardly and that an edge portion extends from the trailing edge convexly relative to the peripheral surface of the sealing rotor.
