摘要： Two-cycle, single vane impeller, hinged hub rotary engines are simple embodiments of a new class of engines. The 2-cycle, hinged hub rotary engines have dependently rotating impellers with, interdigitated, alternating hub sections, a hinge like rotation joint. These 2-cycle engines have expansion and exhaust cycles. The intake and compression cycles are performed by a synergistic air compressor (fan or piston type). Fuel and oxidizer (e.g. compressed air, from a synergistic air compressor,) are injected, to create combustion mixtures, and spontaneously ignited to start the expansion cycle in the minimized expansion sector(s).

摘要： A free-piston bi-directional rotary device is described particularly useful as a compact, low-RPM, high-torque hydraulic motor, but which may also be useful for other applications such as rotary pumps, rotary engines, and the like. The rotary device comprises a stator, a rotor mounted coaxially for rotary movement with respect to the stator and spaced radially therefrom to define an annular gap therebetween, and a plurality of pistons movable within the annular gap in a circumferential direction. Each of the pistons is formed with a slot, and a coupling bar is disposed within the slot and is shiftable radially from a first position coupling the piston to the stator, to a second position coupling the piston to the rotor. The positioning means includes a hydraulic distributor which controls the flow of a pressurized fluid to the coupling bars in timed relationship to the rotation of the rotor, such that the bars are alternately coupled to the stator and to the rotor, to form alternating expansible and contractable chambers between successive pistons as the rotor rotates with respect to the stator.BACKGROUND OF THE INVENTIONThe present invention relates to rotary devices of the free-piston type. The invention is particularly useful with respect to low-RPM, high-torque bi-directional hydraulic motors, and is therefore described with respect to that application, but it will be appreciated that features of the invention could be used in other applications as well, such as hydraulic pumps, rotary engines, and the like.BRIEF SUMMARY OF THE INVENTIONAccording to the invention, there is provided a rotary device comprising a stator, a rotor mounted coaxially for rotary movement with respect to the stator and spaced radially therefrom to define an annular gap therebetween, and a plurality of pistons movable in a circumferential direction within the annular gap. Each of the pistons includes a coupling member movable from a first position coupling the piston to the stator, to a second position coupling the piston to the rotor. Positioning means are provided for selectively shifting the coupling members such that they are alternately coupled to the stator and to the rotor, to form alternating expansible and contractable chambers between successive pistons as the rotor rotates with respect to the stator.In the preferred embodiment of the invention described below, the coupling members are in the form of bars and each is shiftable in a slot extending in a radial direction through its respective piston. Also in the preferred embodiment, the positioning means for selectively shifting the coupling bars comprises a source of pressurized fluid and a hydraulic distributor controlling the flow of the fluid to the coupling bars in synchronized timed relationship to the rotation of the rotor.As indicated earlier, the preferred embodiment of the invention is a bi-directional hydraulic motor. In this embodiment, the rotary device includes a source of driving fluid, means for introducing the driving fluid into the chambers to cause them to expand and thereby to rotate the rotor, and means for removing the driving fluid from the chambers during the contraction thereof.Another described application of the invention is a pump, in which the rotary device includes a drive for driving the rotor, means for introducing fluid to be pressurized into the chambers as they expand by the rotation of the rotor, and means for removing the resulting pressurized fluid from the chambers as they are contracted by the rotation of the rotor.The invention, and particularly the arrangement for providing the alternating expansible and contractable chambers, could be used in other applications, e.g., in rotary combustion engines.Further features and applications of the invention will be apparent from the description below.

摘要： An oscillatory rotary engine comprising a toroidal housing having an intake port and an exhaust port. The housing supports an output shaft and a plurality of stacked rotors are disposed within the housing and coupled to the output shaft. Each rotor includes a plurality of pistons disposed in spaced relation to each other about a circumference of the rotor. A resilient coupler connects the rotors to the output shaft. Preferably, the coupler comprises a plurality of nested spiral cuts extending through the rotor. Each piston may include a pawl that is operative to engage ratchets located around the housing, thereby allowing rotation of each rotor in only one direction. The oscillatory rotary engine may further include a compression bypass port that is operative to relieve intake air pressure during compression, whereby the engine has a compression ratio that is less than its expansion ratio.

摘要： A rotary internal combustion engine including a plurality of toroidal cylinders and toroidal pistons that are slidably carried within the cylinders. Combustion of an air-fuel mixture within the respective cylinders provides a series of circumferential power strokes for more efficient operation. The pistons and cylinders are carried by a pair of side-by-side, coaxial drive rotors, the output power pulses of which are transmitted through a drive clutch and planetary gear assembly to an engine output drive shaft. The drive clutch and planetary gear assembly includes four overrunning clutches and a planetary gear train to smoothly transmit the successive intermittent engine power strokes to the output drive shaft.

摘要： An engine having valve means, timing means, fuel distribution means and ignition means configured for operation on a combustible mixture of fuel and air, or other energy source, comprises at least one annular cylinder and mating annular piston forming combustion chambers at both ends and configured for orbital rotation about a central crank. Escapement means transfers orbital rotation of the piston and cylinder in a first direction to the crank and prevents their rotation in the opposite direction relative to the grounded frame which encloses the engine. The piston and cylinder alternately are rotated in the first direction by expansion or contraction of the energy source in successively predetermined combustion chambers on each stroke to rotate the crank.

摘要： A multi-stroke engine for converting energy into torque is described including two rotors and a housing along surfaces of revolution of genus 1 about same axis. In the preferred configuration a cavity of revolution is used, generated by the revolution of a rectangle about the axis, two sides of the rectangle being parallel to the axis; one half of the cylindrical surface generated by the side nearest the axis is allocated to each rotor, while the surface generated by the other three sides of the rectangle is allocated to the housing. n substantially similar diaphragms having azimouthal thickness substantially equal to 90/n.degree. extend from each rotor at azimouthal angles 360/n across the cavity of revolution and are interleaved with the diaphragms of the other rotor so that the diaphragms divide the cavity of revolution in 2n chambers the volume of half of the chambers increasing while the volume of the others is equally decreasing as the rotors are pressured to rotate with respect to each other. The chambers are assigned to execute sequential strokes of predetermined cycles; cycles involving 2, 4, 8 and 10 strokes are described with the complex cycles also used for converting heat in unburned hydrocarbons, and heat trapped on the walls of the chambers and in the hot exhaust gases to useful torque. The average rotational motion of the rotors is combined through a differential gear assembly into rotation of a center shaft. Means are provided for limiting the reverse rotation of the rotors, the rotors execute average rotational displacements equal to 180/n.degree. per power stroke. A plate rotating with speed equal to the center shaft serves to program the particular cycle, to sequence strokes and to advance the stroke pattern. Means are also described for sealing the volumes between chambers, for lubricating surfaces in relative motion, for cooling and for starting the engine. Relatively lightweight, small volume, and efficient power plants are described when the engine is combined with auxiliary components normally used with such power plants as hydrostatic, geothermal gaseous pressure, steam, gasoline, and Diesel power plants.
