    A tandem machine with opposite free pistons comprising at least two groups of motor pistons-cylinders (A, B) and compressor cylinders and the moving parts of this machine provide two gears. The compressor cylinders of the outer moving gear are arranged outside cross bars (23, 24) on which the outer motor and compressor pistons are fixed (3, 6, 15, 16, 17, 18); these cross bars are interconnected by connecting rods (25, 26). The machine may comprise a plurality of motor units and a plurality of compressor units, and provide a gas self generator.

    This invention relates to internal combustion engines.
    The free-piston machines (SPM) of the tandem type, containing at least two parallel, internal and external cylinder-piston groups with linearly mounted compressor rings and working cylinders, compressor and working pistons, external of which are connected by external crossbars and are interconnected by at least one longitudinal Binding element, and internal ones are interconnected by an internal cross member. During the combustion of fuel in the working cylinders, the external cylinder-piston groups make, due to the presence of bonding elements, a coordinated movement relative to the internal cylinder-piston group, as a result of which the compressor tandem type is alternately compressed in the compressor cylinders and has a higher specific power than the existence of interconnected groups of reciprocating pistons, causes the occurrence of significant bending moments and inertial forces that cause vibrations, especially in the communication elements of external piston groups. This limits the number of SPM cycles, and therefore, increases the power density of the machine.
    The goal of the invention is to increase the power density of the PSD.
    The goal is achieved by reducing the bending and inertial forces acting on the elements of the movement mechanism, and is accomplished by a certain mutual arrangement of the compressor and working cylinders relative to each other and the introduction of additional connections. For this, the external compressor pistons are located on the outer sides of the external crossbars, and pistons.- with their internal CTopo-i; we, and the external cross-pieces of the external cylinder-piston groups are equipped with guide rods, which are mounted between two fixed, internal and external brackets, to the external of which are attached to the outside of the compressor cylinders. On both sides of the outer crossbars, fixed bearings can be installed in order to move them, and the machine itself for dynamic stability is provided with a frame covering the compressor cylinders of the inner cylinder-piston group.
    To reduce the bending moments, the outer cross members can be interconnected by means of two longitudinal connecting elements located in the plane of the outer compressor cylinders and provided with guides in the form of at least one sleeve, fixedly fixed on the corresponding crossbar and installed in stationary bearings one spaced apart from each other, at least four diameters of the sleeve.
    In addition, the axes of the working cylinders can be positioned so that they form a rectangle, the axes of the outer compressor cylinders are located on the vertical center line of this rectangle, and the axes of the inner compressor cylinders - on its continuation.
    FIG. 1 shows the basic structural scheme of the PSM with two external and internal cylinder-piston groups; in fig. 2 - a machine whose working cylinders form a rectangle, a cross section.
    The tandem free piston machine contains at least two parallel, inner 1 and outer 2 piston / cylinder groups with linearly mounted compressor 3 and 4 and working 5 cylinders, compressor b, 7 and working 8 pistons, the outer ones of which are the outer crossbars 9 and are interconnected by longitudinal connecting elements 10, and the inner ones are interconnected by an inner crossbar 11. The outer compressor pistons 7 are located on the outer sides of the outer crossbars 9, and the working pistons 8 - on their inside renney side (FIG. 1). The axes of the working cylinders 5 can be arranged in such a way that they form a rectangle, the axes of the outer compressor cylinders 4 are located on the vertical center line of this rectangle, and the axes of the inner compressor cylinders 3 - on its continuation (Fig. 2).
    The steering crossbars 9 outer cylinder-piston groups 2 are equipped with guide rods. 12, set between two fixed internal. 13 and external, - 14 brackets, to the external one of which 1 external compressor ones are attached. cylinders 4. In order to increase rigidity, the compressor cylinders 3 of the inner cylinder-piston group 1 are additionally equipped with a bed 15 which covers them.
    In versions without brackets 13 and 14 to reduce the curving inertial and vibration loads on both sides of the outer frames 9, the rods 12 are rigidly attached, fixed bearings (not shown) can be installed | to guide the rods during their reciprocating motion, or the crossbars 9 and 11 are provided with guides in the form of at least one sleeve, fixed to a corresponding crossbar and mounted in stationary bearings (not shown), spaced apart from each other in less least equal to four diameters of the sleeve.
    Free piston machine works as follows.
    The inner 1 and outer 2 cylinder-piston groups, including compressor 3.4 and working 5 cylinders with pistons 6, 7 and 8, reciprocate towards each other due to the presence of longitudinal connecting elements 10. Due to the straight the axes of the working cylinders 5 and the placement of the axles of the external compressor cylinders 3 on the vertical line, and the axes of the internal compressor cylinders 4 - on its continuation during the movement of the piston
    groups 2 additionally significantly reduces lateral forces, and the presence of internal il and external 9 cross-beams, guided by longitudinal connecting 10 and guiding rods 12 installed between brackets 13 and 14 (or in bearings), significantly reduces the length of the arms, and therefore, bending moments affecting all elements of the movement system, in particular, on external compressor cylinders 4 and their pistons 7. Additional rigidity of the system is also created due to the frame 15, covering the internal compressor cylinders 3, and e, by using STILL) GOVERNMENTAL bearings for vozvratnopostupatelnogo motion guide rod 12 or sliding guide sleeves crossbars 9 and 11 in their bearings that reduce the friction loss.
    The SPM compressor cylinders can be made in the form of dual-action compressors and equipped with the appropriate air distribution units (not shown), and the engine part of the machine can be equipped with nozzles, lubrication system, air supply, etc.
