ABSTRACT:
A reciprocating engine for water pumping or air circulation is disclosed which uses solar energy from a black box collector or other low temperature heat source to expand and contract bellows thereby providing large forces with low pressures by taking advantage of large working areas available with bellows. The engine is essentially a constant pressure, variable volume thermodynamic cycle engine having a compressor, a heater and a driver with the compressor and the driver sections both being bellows, the driver being capable of operating the compressor section by means of the former enjoying a force advantage or a mechanical advantage over the later.
