Abstract

1478209 Hot gas engines UNITED STIRLING (SWEDEN) AB & CO KB 12 Aug 1975 33470/75 Heading F1S In a hot gas engine power control system of the kind comprising a compressor 7, 8 including a compressor piston 5, 6 connected to a working piston 3, 4 of the engine, a variable volume space 26, 27 in the compressor, connected to a working chamber 13, 14 in the engine via a connection allowing flow of gas only in the direction from the working chamber into the variable volume space, a high-pressure gas reservoir 21 connected to the variable volume space via a connection 40, 41 allowing flow of gas only in the direction into the reservoir and a controllable connection 19, 20 between the reservoir and the working chamber, the connection between the working chamber and the variable volume space of the compressor includes a constant volume chamber 52, 53 of a size at least equal to the maximum size of the variable volume space and a non-return valve 54, 55, 56, 57 provided at the inlet to as well as at the outlet from the constant volume chamber. As shown engine may be a multi-cylinder engine and the reservoir may be connected to a plurality of compressor variable volume spaces. As soon as the desired output of the engine is obtained three way valves 44, 45 are set in positions in which the conduit 40 is connected to the conduit 46 while the conduit 41 is connected to the conduit 47 Gas may now be returned from the variable volume spaces to the engine working chambers 13, 14 without any compression.
