This invention relates to mechanical engineering and steam engines can be used.

The aim of the invention is to increase the efficiency of the engine.

The drawing shows the engine rodal section.

The steam engine contains a heater 1 with inlet and outlet nozzles 2 and 3, respectively, at least one working cylinder 4 and one compressor cylinder 5. In the compressor cylinder 5 and on the inlet pipe 2 of the heater 1, nozzles 6 are installed for supplying condensate, made by shaft duster frequency 7. Work 4 and compressor 5 cylinders are connected to a common shaft 7 and communicate with each other through channel 8 and a check valve 9, open to the side of the compressor cylinder 5.

The nozzles 6 are connected by a pipeline 10 to a hydraulic pressure accumulator 11 and through a pump 12 to a condenser 13 equipped with nozzles 14 and 15 for supplying and discharging the working fluid, respectively.

The condenser 13 is connected via a compressor cylinder 5 via a pipe 14 for supplying a working fluid, and through a pipe 6 is connected via parallel pipe 15 to a heater 1 and a compressor cylinder 5 respectively. 3 working 4 and compressor 5 cylinders accommodate pistons 16 and 17, respectively.

The engine works as follows.

. When the engine is started up, the condensate in the dispersed phase is injected into the heater 1 from the hydraulic accumulator 11 through the nozzle 6. The steam expands, pushes the piston 16 of the working cylinder 4 down, and the engine shaft 7 is rotated at a certain angle. When the piston 16 moves downward, the steam after partial expansion flows through channel 8 into the compressor cylinder 5. Further expansion occurs simultaneously in the working 4 and compressor 5 cylinders.

The movement of the piston 17 of the compressor cylinder 5 is lagging in phase from the moving engine. The order of 6327/25

LIA of the piston 16 of the working cylinder 4. When the piston 17 approaches the lower dead point, some of the steam goes through the nozzle 14 (- supplying the working fluid enters the condenser 13. When the piston moves upwards, the steam pushes into the compressor cylinder 5, in which after closing the nozzle 14 the compression process and after the piston 16 starts to move down from the top dead center, the compressed vapor from the compressor cylinder 5 enters the heater 1. At the same time, the dispersed phase of the condensate is injected again. The cycle repeats.

When the engine is running, the condensate in the nozzles 6 comes n-directly from the condenser 13. The hydraulic pressure accumulator 11 is used only when the engine is started.

When the engine speed is changed, the condensate supply through the nozzles is redistributed by the nozzles so that when the nominal speed is higher, the flow of condensate to the heating cavities is stopped, and when the engine speed drops below the nominal speed, it is resumed.
