EXTERNAL COMBUSTION ROTARY VANE ENGINE

摘要

The invention provides an engine (10) having a housing (12) defining a compressor (26) having an inlet and an outlet, a combustion chamber (92) and a power unit (28) having an inlet and an outlet. The combustion chamber (92) has an inlet which is connectable in flow communication with an outlet of the compressor and an outlet which is in flow communication with an inlet of the power unit. Each of the compressor and power unit (28) includes a rotor mounted in a complementary chamber having a pair of part-circular lobes. The rotor is mounted concentrically with one of the lobes and eccentrically relative to the other lobe. Seals are provided on the rotors. The compressor feeds air, under pressure, into a reservoir (90). Air is fed from the reservoir (90) into the combustion chamber where it is mixed with fuel and ignited. Exhaust gases are fed from the combustion chamber into the power unit to extract useful work.
