Abstract
A system is disclosed incorporating a positive-displacement compressor-and-engine arrangement for converting heat of a working fluid to attain a pressure increase in a working fluid that is supplied to a turbine system. The system employs a heater interposed to pass exhaust fluid from the drive engine to the turbine system at an elevated temperature. As disclosed, the housing of the compressor-and-drive structure incorporates cooling apparatus, for example so that the reciprocating compressor may approach isothermal operation. Also, the turbine system is divided into one unit which supplies mechanical output power and another to drive a rotary compressor or supercharger, which supplies intake fluid to the positive-displacement compressor, the output of which supplies the positive-displacement engine.
Claims10
An engine system for providing mechanical power from heat energy, comprising:
- positive displacement means including a positive displacement compressor and a positive displacement engine for driving said compressor;
- means in series with the positive displacement means for adding heat energy to raise the temperature of a working fluid;
- a rotating system including turbine means adapted to be connected to provide mechanical power;
- and
- means connecting said compressor and said engine with said rotating system to transfer said working fluid therebetween at an increased pressure of working fluid applied to said turbine means.
