    A thermocompressor is disclosed as including a free piston which coasts upwardly and downwardly in a bypass region of a cylinder between cold and hot rebound chambers at cold and hot ends of the cylinder located at the top and bottom of the cylinder. A compressible fluid alternately flows downwardly and upwardly between the cold and hot cylinder ends via the cylinder bypass in response to the alternate upward and downward coasting of the piston. This alternate fluid flow, in conjunction with a thermal lag heating chamber, regenerator, and cooling chamber, causes an alternate heating and cooling of the fluid which produces a cyclical fluid pressure variation utilizable for driving a load. Although the regenerator, and generally the cooling chamber, are located in the bypass, the thermal lag heating chamber is located beyond the bypass and communicates separately with the lower or hot end of the cylinder for thermal lag driving of the piston during a hot rebound portion of the cycle. During the upward coasting of the piston, fluid is directed out of the hot end of the bypass in a substantially defined stream which flows through a portion of the volume of the hot cylinder end and thence into the heating chamber via a heating chamber inlet port and inlet conduit, thereby producing the required heating during coasting. The inlet port is positioned within the cylinder and very close to the lower or hot end of the bypass for capturing substantially all of the above-mentioned stream of fluid substantially independently of the choice of fluid. The lower or hot end of the free piston is concavely shaped such that it does not strike or undergo substantial frictional contact with the cylinder end-wall defining the inlet port and inlet conduit even though the lower edge of the piston moves below the port during the hot rebound.

    (54) FREE PISTON MOTOR COMPRESSOR WITH EXTERNAL

    The invention relates to the field of engineering, namely the engine, and can be used to create a free-porous engine, operating on the Stirling cycle and intended, for example, for a liquid pump with a pulsating injection pressure.
    IzBest1P) free-piston engines with external heat supply, containing a cylinder with D1SCHLMI, a free piston separating about 61) 0 m of a cylinder on a hot and cold cavity, interconnected by a bypass pipeline with a regenerator included in it, and a heating chamber - ru connected by pipeline to the hot cavity of the cylinder 1.
    The working medium of these engines is. gas, for example gel, which fills the entire internal volume of the engine.
    The working fluid, while heating the heating chamber, dissolves, flows into the hot cavity and your pump raises the piston upwards, the pressure in the cavities rises. Lift up, HEATING
    It opens the bypass hole of a hot cavity, and the working fluid flows from the cold cavity through the bypass pipeline and the regenerator into the hot cavity, on the way to collect heat accumulated in the regenerator. In the volume of the hot cavity, as the piston moves, the temperature and pressure of the working fluid increase. A certain amount of working fluid before the upper dead strka enters the heating chamber. Raising further upwards, the piston closes the bypass opening in the cold cavity, which counts the process of cold removal of the piston, i.e. movement cond. At the same time, the working tank flows into the cold cavity, giving its
    I5 heat to the regenerator. The cavity pressure gradually begins to decrease. When the bypass hole is closed, the piston starts. He moves his moving body and pushes the working fluid into the heating chamber;

    20 it grows in the hot cavity, and in the cold cavity it falls. The process of hot piston jigging begins, i.e. its upward movement. The process is repeated. Thus, due to the alternating heating and cooling of the working fluid, porish is periodically moved and the pressure change in the cavities, which is used to drive any i unit,. The disadvantage of the known engine, which reduces its efficiency, is the fact that that the working fluid flows from the bypass hole of the hot cavity into the heating chamber and back through the whole volume of the hot cavity, as a result of which each cycle a significant amount of the working fluid from the bypass hole does not enter the chamber eva. The aim of the invention is to increase the engine HFV. This goal is achieved by the fact that the bottom of the hot bulness of the cylinder is provided with an internal protrusion with an inlet pipe passing through the protrusion from the heating chamber towards the end of the bypass - a burning cavity, and the piston is made in a form that allows which the bypass during the hot beating process, in addition, the protrusion can be made in the form of a rod with an internal channel, and the surface of the piston facing the hot cavity can have a more common shape, and the heating chambers provided with an outlet pipe extending through the protrusion into the hot chamber and the distance between up responses pation hot end of the bypass orifice and the inlet pipe placed in the hot cavity mensche than 0.1 radius tsilind FIG. 1 shows a schematic diagram of a free-piston engine with an external heat supply; Fig. 2 shows a variant of connecting the heating chamber to the hot cavity of the engine cylinder. The engine contains a cylinder 1 with a distance 2 and a bottom 3, equipped with a protrusion 4 forming a gap 5 with the wall of the cylinder, a piston 6 with a thin-walled segment 7 freely entering the gap, a cold 8 and a hot 9 cavity of the cylinder separated by a piston and connecting rod 1e between through the bypass line 10 with a cold end I, ending with a hole 12 in the cold cavity, and a hot end 13, ending with a hole 14 in the hot cavity, XO boat 15 and a regenerator 16, included in the bypass pipe, inlet pipe 17 with a hole 18 in the ring The hot gap of the hot cavity and the exhaust pipe 19 with an additional cartridge 20 placed in the bottom projection and connected to the heating chamber 21, heated from outside by a stem or thermal body 22, has a heating disk 23 forming gas chambers 24 for heating the working fluid, and contains a comb 25, positioned against one of the ribs and passing approximately in the middle of their set, starter device 26 and pipe 27 for connecting a consumer. The engine is running as follows. The preheating chamber 21, due to the heat introduced into it through the pipe 22, transfers heat through the fins 23 to the working fluid, which fills the internal volume of distance 1, and the pressure begins to increase. To start the engine, the piston b through the starter unit 26 gives an initial pressure impulse, as a result of an increase in the pressure of the working fluid in the hot section 9. The piston begins to move upward with energy sufficient to force the working fluid out of the cold cavity 8 through the bypass pipe 10, cooler 15 and a regenerator 16 in the hot end of the 13 bypass conduit. The working fluid flows out of the hole 14 in the form of a jet that intersects the gap 5 and flows into the opposite opening 14, the outlet 18 of the inlet duct 17 and through it into the heating chamber 21, and the heated gas flows freely into the hot cavity 9 from the heating chamber 21 through exhaust pipe 19 while the piston is still moving upwards. As a result of heating the gas in the regenerator and the heating chamber, the pressure increases, which causes the cold gas to flow from the cold cavity 8 to the consumer through the pipe 27. After the piston blocks the opening 12 of the cold end 11 of the bypass pipe and the opening of the pipe 27, at the same level, the compression of the gas locked between the bottom 2 and the piston 6 begins, the gas acts as a spring, throwing the piston 6 down and preventing it from hitting the bottom 2. This completes the first process of the Sch3 and the cold baffle Ikla, After otbivaets piston downward, it unlocks stie side surface 12 and orifice nozzles 27, the process ends and cold weaning process begins moving in the second cycle. During portions moving downwards, the preheated gas rushes through the bypass pipeline 10 through the regenerator 16 and the cooler 15 from the hot cavity 9 into the cold cavity 8. As a result of the cooling of the gas in the regenerator and the cooler, the pressure in the inner loop drops, this pressure drop 5 causes The cold gas does not flow back from the load into the cold cavity 8 through the load nozzle 27. The regenerator 16, which accumulates and releases heat from the gas in each cycle, increases the amplitude of pressure fluctuations, thereby increasing the efficiency of the cycle. While continuing to move the porish down, the thin-walled segment 7 of the piston 6, the entrance to the gap S, covers the protrusion 4 of the bottom 3 and blocks the opening 14 of the hot end 13 of the bypass. The second process of movement in the cycle ends and the process of hot shoving begins. Hot spraying is obtained by shrinking and compressing the piston 6 in the annular gap S n in the heating chamber 21. Heating camarl 21 provides thermal power to the gas during hot pick-up, necessary support for the backward translation and loading of the load, and the presence of a protrusion 4 in which the inlet pipe 17 passes allows reducing losses when gas flows from the bypass to the heating chamber, since gas flow in this case occurs through a narrow gap and the gas jet does not have time to noticeably blur, which allows an increase of the engine efficiency.
