摘要： A rotary motor/pump operating from pressurized elastic fluids (steam, and gases of all types), and a pump for either elastic or incompressible liquid fluids. With a combustion chamber (52) installed, motor (20) will also operate as a gas engine. The motor (20) comprises a casing (22) surrounding at least one pair of rotors (30) mounted on parallel shafts (28). The motor (20) is provided with inlet port (24) which admits high pressure steam or gas. Pressure is confined and applied continously and simultaneously to two outwardly extending lobes (34) which instantly apply torque to shafts (28). Cooperating cavities (40) permit lobes (34) to pass through the adjacent rotor (30) and maintain a seal during the passage. Timing gears (32) are attached to shafts (28) and maintain synchronization between lobes (34) and cavities (40). The motor (20) may be converted into a multistage compound steam engine by conducting exhaust gases from outlet ports (26) into the inlet ports of following stages of larger volume, and used with a condenser to enhance efficiency. Detailed functional analysis of the lobe/cavity relationships are included.

摘要： A motor/pump includes a cylindrically shaped rotor journaled within a similarly shaped housing to define an annular fluid passageway therebetween. The annular passageway is divided into a plurality of discrete fluid chambers by mobile blocking members which are mounted on the rotor near its periphery and stationary blocking members which extend outwardly from the housing to block fluid passage. Both types of blocking members are preferably free to rotate in place. Fluid inlets and outlets positioned around the annular chamber alternately pressurize and depressurize the chambers formed by the blocking members. The stationary blocking members are coupled to the rotor for synchronous rotation to allow passage of the mobile blocking members thereby. One preferred embodiment includes dampeners in the fluid inlets and outlets so that rotation of motor/pump can be controlled to provide the desired motor/pump characteristics.

摘要： This machine can serve as a compressor or motor and, more specifically combines a compressor and a motor to constitute an internal combustion engine with compressed air injection. A toothed rotor is rotatable in a fluid displacement chamber and in sealing contact with a sealing rotor having peripheral cavities for receiving the teeth of the toothed rotor. Both rotors are axially curved, so as to better resist differential axial thrust exerted on the same and, therefore, maintaining better sealing contact. The teeth of the toothed rotor are generally of a hemispherical shape to facilitate the provision of effective sealing segments. When used as an internal combustion engine, a combined fuel injection and ignition device is provided enclosed within a sleeve rotatable within the engine housing, the sleeve having a lateral opening which can be made to selectively register with one of two housing passages opening in two adjacent fluid displacement chambers, with the result that the engine can be reversed by the simple rotation of the ignition device enclosing sleeve.

摘要： An external combustion engine is disclosed of the type including two or more circular rotors rotatably supported, one of the rotors acting as a power rotor and rotating in tangential contact with the other sealing rotor. The power rotor is formed with a radially projecting piston passing into a mating recess with the sealing rotor at a corresponding circumferential location. Steam or other working fluid is admitted via an intake port located opposite one face of the power rotor to cause rotation of the power rotor by expansion of the fluid in a working chamber defined by the space behind the piston. As the power rotor continues to rotate, the working chamber passes into communication with an exhaust port preparator to another power stroke. A vacuum relief port is provided at an intermediate location which relieves any vacuum condition which develops behind the piston during part throttle operating conditions of the engine. A pressure balancing groove is located on a face of the power rotor and pressurized with working fluid to balance the pressure acting on the power rotor by the location of the intake port on the opposite face of the power rotor. An absorber chamber is provided downstream of the throttle valve and upstream of the intake port to smooth out the pressure forces created by intermittent flow of fluid through the intake port. An elliptical port throttle valve design is disclosed which minimizes the wire drawing effect of the working fluid acting on the valve member during operation of the valve. A special rotor sealing surface treatment is disclosed comprising a series of slight depressions or holes formed in the mating faces of the power rotor and which generate a sealing due to condensation of the escaping steam in the surface indentations. Two and three rotor versions of the engine are described as well as one, two, and four power stroke per revolution embodiments.

摘要： Internal combustion engine includes a rotary oxidizing gas compressor, a constant volume combustion chamber with pneumatically controlled intake and exhaust valves and a fuel injector, and a rotary combustion gas expander. Each of the rotary compressor and rotary expander has a pair of tangential rotors dependently rotatable in a housing, one rotor having a vane and the other a notch for allowing passage of the vane, to form a fluid tight segmented annular region through which the vane moves. The respective one of the intake valve and the exhaust valve admits a mass of high pressure compressible fluid to the region through a triangular port for expansion or from the region after compression, the mass of fluid being confined in a part of the region between the vane and the surface of the notched rotor and changing in pressure because of the change in arcuate length and volume of the confined part. The respective pairs of rotors are included on the same respective shafts. Two vanes may be included on the one rotor and two notches on the other. Two vaned rotors may cooperate with one notched rotor, the vaned rotors being on separate shafts.

摘要： A rotary engine for use as a fluid motor or pump which employs a rotor carrying pistons that are adapted to rotate within a circular chamber. A working fluid is introduced into and exhausted from the chamber through inlet and outlet ports provided on opposite sides of a rotary blocking valve. The blocking valve is formed with a concaval recess and is driven to turn conjointly with the pistons so that the latter are successively enveloped within and move across the blocking valve. The inlet port and blocking valve are arranged to provide an effective pressure stroke of greater than 120* for a three piston engine to prevent stalling and deadspots in the engine''s operation. The engine is dynamically balanced for high speed operation in the manner of a turbine. Close-spaced, frictionless clearance between the piston and chamber walls is provided. Fluid leaks at a controlled rate around the pistons to form a backpressure in the trapped volume ahead of the pressurized volume. Fluid leakage around the rotor is controlled due to back pressure developed in the pressure sealed housing enclosing the elements.

摘要： An automatic torque conversion system is described wherein the combination of a continuous combustion engine of the rotary type and a rotary compressor can be linked with a planetary differential gear with the resultant delivery of output rotation being variable from zero to maximum according to the load on the output, the engine speed being adjusted to the desired amount of ouput torque wanted. When no output rotation is desired on the output shaft, the generated power is delivered internally to the compressor. The system operation is minimally pollution free and provides high efficiency of power conversion when an output rotation is being delivered.

摘要： A rotary energy converter which may be embodied as a compressor, a utilizer, or a continuous combustion engine. Circular annular chambers are used to house a rotating piston rotor and two rotary abutment type peripheral valving rotors, wherein all the rotors are linked in a timed relationship. External torque may be applied to compress gases or fluids; compressed fluids may be intaken to provide mechanical output from the converter; or internal combustion may be used to provide a mechanical power output. Sealing between function-chambers is provided by nonfrictional juxtaposition of chamber walls with the rotary piston and rotary valving abutments. An optimum interleaving arrangement is provided between the central rotor pistons and the cavities between the peripheral valving rotor abutments. Only three basic moving parts are required to accomplish all phases of the energy conversion described in the above embodiments. The side faces of the rotating central pistons are formed from the arc of a single circle while the side faces of the cavity between the peripheral valving rotor abutments are also formed along the arcs of another circle. The embodiment of a continuous combustion engine portends great abilities for the large scale reduction of undesirable emissions normally produced by combustion in addition to simplicity of design and ease of fabrication together with economy of operation.
