<p>Process for conversion of low value thermal energy into mechanical energy by thermal expansion of an inert liquid expansion medium, which in a relatively low temperature range of not higher than 80°C has a relatively high expansion coefficient, which medium is contained in pressure tubes (3) included in a regeneration cylinder (1), which pressure tubes are stepwise heated or cooled by a thermal medium circulating in the cylinder without parts of the thermal medium with different temperatures being intermingled. Examples of the expansion medium are paraffins.</p> |
