Abstract

The invention relates to a machine for converting heat into mechanical energy comprising an expansion device producing mechanical energy from a flow of vapor of a fluid; an evaporator heated by a heat source to a high temperature and configured to supply the expansion device with vapor; a condenser cooled by a heat sink to a low temperature and configured to condense the vapor discharged by the expansion device; a liquid circuit configured to transfer fluid in liquid phase from the condenser to the evaporator; a vapor circuit configured to transfer fluid in vapor phase from the evaporator to the condenser; and valves configured to, in a first, active stroke, close the liquid and vapor circuits, and, in a second, inactive stroke, open the liquid and vapor circuits.

Abstract

The invention relates to a machine for converting heat into mechanical energy, comprising an expansion valve (EXP) producing mechanical energy from a flow of vapour of a fluid, an evaporator (EVAP) heated by a heat source (Sh) at a high temperature (Th) and configured to supply the expansion valve with vapour; a condenser (COND) cooled by a cold source (Sb) at a low temperature (Tb) and configured to condense vapour delivered by the expansion valve; a liquid circuit (VL) configured to transfer the fluid in the liquid phase from the condenser to the evaporator; a vapour circuit (VV) configured to transfer the fluid in the vapour phase from the evaporator to the condenser; and valves configured in order, in a first so-called active time, to shut off the liquid and vapour circuits (VV, VL), and in a second so-called inactive time, to open the liquid and vapour circuits.
