ABSTRACT:
A first mass of driving vapor is admitted into a single chamber of variable volume and permitted to perform isobaric then polytropic work in an expansion which increases the chamber volume. A second mass of vapor derived from the refrigeration cycle is then admitted at constant pressure in order to attain maximum volume. The work performed by the driving vapor is utilized in a polytropic process for compressing the vapor masses which are then discharged to the condenser in an isobaric process when the chamber approaches minimum volume.
