(under subclass 200.1) Apparatus in which an air stream is compressed and led into a combustion chamber in which motive fluid is produced, comprising a passage for causing a portion of the air, after it has been compressed, to avoid entry into the combustion chamber and be led back into the stream of motive fluid from the combustion chamber before it is ejected into the ambient.
