Abstract

FIELD: power mechanical engineering. SUBSTANCE: device has pressure-tight loop with fluid that includes condenser 1, pump 2, and steam generator 3. The space of the generator is connected with working chamber 4 of a steam machine made up as cylinder 5 and piston 6. The device also has facility 10 for supplying fluid to the space of steam generator 3 that includes a system for batching fluid and synchronizing the supply of the fluid in accordance with cycling a converting mechanism by way of valve 11. The valve is mounted in the line for supplying fluid to the steam generator and controlled by shaft 8. The inner surface of the space of steam generator 3 is finned. Valve 13 is mounted in the line for discharging exhaust steam to condenser 1. Slide valve opening 14 is made at such a point on the cylinder at which the piston reaches the bottom dead center, the volume of working chamber 4 being maximum. Passageway 15 serves for connecting the space of steam generator 3 with opening 14. The volume of working chamber 4 is no less than the volume of a portion of fluid that is supplied through facility 10 in one cycle being multiplied by the ratio of the steam density to the fluid density referred to parameters in the space of steam generator 3. EFFECT: enhanced efficiency. 1 dwg

Claims (1)

To ensure the conversion into mechanical work of thermal energy from low potential sources, the installation contains a sealed circuit of the working fluid, including a condenser 1, a pump 2 and a steam generator 3, the cavity of which is connected to the working chamber 4 of the steam engine, made in the form of a cylinder 5 and a piston 6. The installation also contains a device 10 for supplying liquid to the cavity of the steam generator 3, including a system for dispensing a volume of liquid and synchronizing the supply of this volume in accordance with the cycle of movement of the transforming mechanism with by means of a valve 11 installed on the liquid supply line to the steam generator and controlled from the shaft 8. The surfaces of the steam generator 3 are made with a rib 12 of the internal cavity. The valve 13 is installed on the exhaust steam exhaust line to the condenser 1. The spool hole 14 is made in that place of the cylinder 5, which reaches the piston at bottom dead center with the maximum volume of the working chamber 4. Channel 15 is made to connect the cavity of the steam generator 3 with the hole 14. In this case the volume of the working chamber 4 is selected not less than the volume of the dose of liquid supplied through the device 10 in one cycle, multiplied by the ratio of the densities of vapor and liquid with parameters in the cavity of the steam generator 3.
