  • Publication number: 20110000205
    Abstract: When converting thermal into mechanical energy by a working medium containing a mixture of at least two materials having different boiling and condensation points, which is fed to a condenser, and is condensed therein, the condenser condensation pressure may increase and the efficiency for generating the mechanical energy thus decreases because the mixture of materials is separated into a liquid phase and a vapor phase upstream of the condenser. To prevent this, the liquid phase of the working medium is mixed with the vapor phase of the working medium before or while the working medium is condensed, thus once again creating a homogeneous mixture of materials which condenses at a lower pressure than the separated working medium, thereby preventing loss of efficiency. This can be applied to the use of thermal energy from low-temperature sources such as geothermal fluids, industrial waste heat, or waste heat from internal combustion engines.

  • Patent number: 4783963
    Abstract: A high temperature, high pressure, four-cycle piston engine having two companion cylinders or multiple pairs of companion cylinders connected by a transfer valve or valves and working together to complete the four-cycle operation. The internal combustion of fuel and air in the ceramic cylinders is utilized as a means of producing heat and this heat is used to generate superheated steam by cyclicly injecting water into the hot power cylinders, with each power cylinder serving as a steam boiler. Ceramic pistons in the power cylinders use the power of the expanding steam to do useful work and operate to exhaust all gases after each power stroke. The engine can be adapted for both compression ignition and spark ignition operation.

  • Patent number: 4432203
    Abstract: A rotary external combustion engine wherein energy is transferred to air acting as a working gas by injection into the air of liquid water at a high temperature and pressure. The liquid water is injected either directly into the working space in the stator or into a preliminary mixing chamber. The water acts as a heat-transfer medium for heating the air. Spontaneous vaporization of the liquid water on injection increases the pressure of the air which drives the rotor before being exhausted. The exhaust water is recovered and recycled. The working space is scavenged and refilled with a fresh charge of air.

  • Patent number: 4037415
    Abstract: A rotary engine includes an outer body arranged to rotate on a stationary member, the outer body having an eccentric circular cavity cooperating with radial vanes from the stationary body which sequentially reciprocate so that a series of volumes sequentially increase and decrease in size. Ammonia gas under pressure is introduced on one side of the vanes and when the volumes containing the gas pass their maximum value and start to decrease, water is injected which is immediately absorbed in the ammonia gas to create a vacuum. As a consequence, a push-pull action is provided in each volume to rotate the outer member about the stationary member. A tire may be held on the outer member to provide a vehicle wheel which serves simultaneously as a rolling support and a driving engine for the vehicle.

  • Patent number: 3975914
    Abstract: A variable volume chamber such as defined by a cylinder and piston has closed circuit connections to a given gas and a given liquid for which the gas has a chemical affinity when in physical contact therewith. By bringing the liquid and gas together in the confines of the closed chamber, the rapid absorption of the gas creates a vacuum or implosion effect which results in the piston being driven by the pressure differential further into the cylinder. The same process can be used to drive a rotary engine, there being required no heat, ignition system, or exhaust to the atmosphere of gas.

  • Patent number: 3972194
    Abstract: A method and apparatus for a thermodynamic machine for the generation of power or for the transport of heat, where a compressible working fluid is compressed and expanded in a cycle using a vane type apparatus. Heat is added and removed from the working fluid by using another fluid within the vane unit housing together with the working fluid. The second fluid is also circulated through external heat exchange means for changing the temperature of the fluid. The working fluid may be a suitable gas, such as a halogenated hydrocarbon or carbon dioxide, and the second fluid may be a liquid such as a light oil which also can provide lubrication within the housing. The working fluid ordinarily remains within the vane type unit housing, while the second fluid is circulated through the outside heat exchanger means.
