    The invention relates to free piston machines.
    The purpose of the invention is to increase the efficiency and simplify the design of a free piston machine (SPM) by implementing a system of interconnected piston groups with a free piston and a sector synchronization mechanism.
    FIG. 1 shows a PSD with an intermediate position of the working and injection pistons; in fig. 2 - SPM at the position of the working and injection pistons in the internal dead point with a fixed free piston; in fig. 3 - the same, with the position of the free, working and injection pistons in the phases of gas expansion; in fig. 4 - implementation of the PSA with coaxial working cylinders, option.
    The free piston machine (Fig. 1) contains at least one working piston 1 with a rod 2 forming with the working cylinder 3 and its head 4 a combustion chamber 5 placed coaxially with it a free piston 6 and a synchronizer 7 of movement of piston groups associated with the worker a piston 1. On the rod 2 of the working piston 1 there is an auxiliary piston 8, which forms with the auxiliary cylinder 9 a pressure chamber 10 and P, and a free piston 6
    It is equipped with an axial one-way valve communicating cavities behind and before the free piston 6, and a fixed device interacting with the working piston 1 when the latter moves in the zone of an internal dead center (TDC), the axial one-way valve and the fixing device are not shown as unlocked catchers. The free piston 6 is slidably mounted on the guide rod 12 placed in the working cylinder 3 and having an elastic device 1 3 (for example, a spring) for supporting the free piston 6. The inlet valve 14 is made in the form of a swinging disc and is installed with the possibility of turning 12, placed in the recess of the stem 2 of the working piston 1, and the outlet - in the form of an axial spool (the details of the working 1 and auxiliary 8 pistons are not shown in detail with the working 3 and auxiliary 9 cylinders Injection pumps 15, 10, and 11. The synchronizer 7 of the movement of the piston groups of the PSM in various embodiments can be implemented either in the form of a sector gear 6 connected with the starting shaft 17 and with the piston rod 2 of the working piston 1, and the gear gear can be made 3 of textile reinforced elastomer, either in the form of a connecting rod connected to the crankshaft and the working piston rod 1, to ignite the air-fuel mixture. In the combustion chamber 5, a ignition plug 18 is provided, controlled by an ignition device installed in the sector hydrochloric gear J6, In various embodiments, the booster piston PSD can be formed (FIG. 4) in the form of two cylinders 19 and 20 of coaxial pistons 21 and 22 installed in the corresponding section, the central coaxial pore of the pin 22 connected to the working piston I, and the peripheral 21 attached to the rod 2. The working pistons with the cylinders are installed parallel to each other and connected to the crankshaft The guide rod for the intake valve disc is made hollow and is located at one end beyond the dimensions of the machine for supplying lubricating oil through it. Free piston machine works as follows. The working piston 1 reciprocates in the slave than cylinder 3 when the fuel-air mixture is burned, in particular from the spark plugs 18, in the combustion chamber 5, as a result of which in chambers 15, 10 and I1 formed by pistons 1 and 8 and cylinders 3 and 9, alternately, the suction-pressure process of the working fluid occurs, which through connecting channels through an inlet valve 14, made, for example, in the form of a swinging disc, enters further into the combustion chamber 5 (Fig. 1). The reciprocating rotation of the disk is provided by rotating it on the guide rod 12 placed in the recess of the rod 2 of the working piston 1. The movement of the symmetrical piston groups formed by the pistons 1 and 8 is synchronized, for example, as a rotary gear wheel 16, the teeth of which can be made from a textile reinforced elastomer connected to the output shaft 17 and the rod 2. The ignition of the fuel-air mixture in the combustion chamber 5 is performed by a candle 18 Gani from the ignition device situated in the cavity sector gear (not shown). In the process of reciprocating free piston 6 when it passes in the zone of the internal dead point (VZH), it is fixed by means of tripping catchers (not shown), driven by the working piston 11 when the latter moves to a position near its lower limit working stroke (figure 2). In this case, after disengaging and closing the intake valve 14, the free piston 6 begins to remove the exhaust gases from the combustion chamber 5, moving together with the working piston 1, but following it at some distance, due to the presence of an elastic device 13, for example in the form of a spring (Fig. 3). As a consequence, after the completion of exhaust, the new portion of the air-fuel mixture gets access to the combustion chamber 5, the passage through the axial one-way valve (not shown) in the free piston 6. At the end of the next compression stroke, the elastic device 13 again presses the free piston 6 to the head 4, where it snaps into place again and, by means of the aforementioned disengaged catchers, is in a fixed position during a part of the stroke. In the presence of coaxial cylinders 19 and 20 with pistons 21 and 22 (Fig. 4), the forces are transmitted to the latter through the rod 2 of the working piston 1, and the supply of lubricating oil through the hollow guide rod for the intake valve disc. Thus, efficient gas exchange is carried out in the combustion chamber, which, in combination with the absence of lateral forces, ensures high efficiency of the machine.
