    The invention relates to mechanical engineering, in particular to engine building, and can be used in the creation of free-piston engines with an external supply of heat and power take-off through a connecting rod-crank mechanism.
    The purpose of the invention is a vision. Engine efficiency
    FIG. 1 is a schematic diagram of the engine; in fig. 2 shows a constructive embodiment of the engine in FIG. 3 shows the occurrence of connections between binding devices, a schematic section; in fig. 4 - a device with connecting means, allowing the workers to obtain the rotational movement of the pistons, a longitudinal section; in FIG. 5 - section aa on. four; in fig. 6 is a schematic diagram of the device with mechanical bonding means.
    The engine (Figs. 1 and 2) comprises a housing 1, made in the form of a cylinder, a pressure vessel, a working piston 2, linearly moving up and down by means of a rod 3, a pressure piston 4, also moving by means of a rod 3, a heater 5, the regenerator 6 and the cooler 7 .. arranged in series, outer 8 and inner 9
    coupling devices of the displacing piston 4, the actuator 10, the cold cavity 11 formed by the displacing piston 4, the working piston 2 and
    housing 1, a hot cavity 12 located between housing 1 and the displacement piston 4. Heater 5 is connected to an external heat source (not shown in detail).
    The displacing piston 4 is connected to a first 13 with the first internal coupling device 9, while the working piston 2 is connected to a 14 internal connection with a BTopbiM internal connecting device 15. Both connecting devices 9 and 15 are made of magnetically soft rings. gland which have radially open outward notches 16 and 17. External binding
    The device 18 of the working piston 2 is located opposite the internal coupling device 15.
    Housing 1 or at least part of the housing around the bonding
    Devices 9 and 15 are made of non-magnetic material. For this, for example, plastic or non-magnetic metal, for example, aluminum or special non-magnetic steel, can be used. In the latter case, there is peace only with the inevitable loss of eddy currents.
    Binding devices 8 and 18 are made of the same annular permanent magnet, which has open-ended annular recesses 19 and 20. Instead of permanent magnets, electromagnets can be used, and electromagnets of direct or alternating current can be used.
    External linking devices 8 and 18 are connected to the same link 21 or 22, with both rods (21 and 22) being axially movable independently of one another. Ti 21 and 22 are connected by hinges 23, 2 25 26 with the drive 10, which is placed on the shaft 27 and is represented only schematically. By selecting the angular position of the hinges 24 and 26, the phase angle between the working piston 2 and the displacing piston 4 is set. The connection between the actuator 10 and the working piston 2 or the displacing piston 4 provides a rigid position of the phases between the working piston 2 and the displacing piston 4 as when starting , and when the load changes.
    FIG. 3 shows how, on the basis of the geometry of the external and internal connections of the connecting devices 8 and 9, which are facing each other by annular recesses 20 or 17, occurs during axial relative movement between the connecting devices 8 and 9, the axial component that creates the required binding force.
    FIG. 4 illustrates an embodiment of the device, with the help of which from the oscillatory-translational movement of the working piston 2 or the displacing piston 4 shown in FIG. 4 conventionally, these pistons are reported by an additional rotational motion (arrow 28) around a common longitudinal axis 29.
    In order to achieve simultaneous and identical rotational movement of the pistons, a core-shaped connection 30 is provided, which is inserted with a gap in the recess 31 or 32 of the pressure piston 4 or the working piston 2. so that the free movement of the pistons relative to each other in the axial direction is possible. Since the notches 31 and 32 and the connection 30 are made in the cut square.

    The pistons (despite the freedom of their axial movement) can only rotate together.
    As a connecting means between the linear movement and the resulting rotational movement, a 33-displacement piston 4, which, when moving, is moving, is made of a non-magnetic material, such as magnetic iron, while the working piston 2 has a corresponding insert 34, which, with respect to the insert 33, describes The motion of the sinusoid, i.e. has a phase shift of 90. The magnets 35 and 36, which interact with the inserts 33 or 34, are attached to the core-tus wall so that during the longitudinal movement parallel to the axis 29 (based on the magnetic component of force described in connection with Fig. 2), the pistons 2 or 4 a continuous rotational movement is achieved in
    5 in the direction of the arrow 28. This rotational movement can be retracted by the magnetic coupling device, which in the embodiment of the device is composed of magnets 37 and 38.
    0 Using the magnetic device 37, you can connect the shaft 39 with the drive mechanism of the secondary unit.
    FIG. 5 shows that relative to the housing 40, the adjusting ring 41, on which the magnets 35 (or 36) are located, can change the angular position of the magnets 35 or 36, as indicated by arrow 42., as well as the phase 0

    the angle between the displacement piston 4 and the working piston 2.
    FIG. 6 shows an embodiment of the device, according to which an adjusting ring 43 is provided inside the wall of the housing 40, there is a cam 44 on it, on the front end of which there are rollers 45. The latter are included in a sinusoidal or sinusoidal annular recess 46
    on the displacement or working piston, and thus serve as a binder for obtaining an additional rotational movement in a straight-line movement of the pistons. Magnetic pairs 47 or 48 allow fixing or changing the angular position of the adjusting ring 43 and so on. in turn, the phase angle between the working and displacement piston.

    The engine works as follows.
    The displacer piston, moving down from the upper dead point, pushes the working fluid from the cold cavity 11 into the hot cavity 12. When

    In this way, the working fluid, the passage through the cooler 7, the regenerator 6 and the heater 5, is heated. When most of the mass of the working fluid is concentrated in the hot cavity, and the working piston 2 is at its highest point, the expansion process begins. The expansion work is transmitted through the working piston 2 to the power take-off shaft. When the working piston 2 moves to the upper dead center, the displacement piston 4 concentrates the main mass of the working fluid in the cold cavity 11, pushing it out of the hot cavity 12 through the heater 5. the regenerator -6 and the cooler 7. The working fluid is compressed at a low temperature. When the porsche 2 and 4 are moving, power is transmitted to them or from them through the internal devices 9 and 15 to the external devices 8 and 18 by means of power electromagnetic lines. To change the phase angle between the pistons, the rivet angle of the cranks is shifted into the crank mechanism and the pistons due to the magnetic coupling between the rig. 8., 18 and 9, 15 change their phase position. To reduce the friction force of the pistons against the walls of the cylinder, there is a device for imparting rotational motion to the pistons.
