Abstract
A power plant including a vane type engine having fuel compression means and a gas expansion means. Air or an air-fuel mixture compressed by the vanes in the compression means is fed to a free piston combustion member where burning takes place and gases are returned to the gas expansion means of the engine to drive the power shaft.
Claims16
A power plant comprising:
- means for supplying compressed air;
- a combustion member including a sleeve with axially spaced inlet means and outlet means and igniting means at each end of the sleeve, a free piston mounted in the sleeve for axial sliding movement and including spaced inlet and outlet means;
- means for introducing fuel to form a fuel-air mixture for burning in the combustion member to produce combusted gas;
- means for imparting rotational movement to the piston as it slides axially so that the inlet and outlet means in the piston are registered with the inlet and outlet means in the sleeve in proper timed sequence to provide intake and exhaust valving functions;
- and
- means for receiving and expanding the combusted gas to drive a power delivery member.
