Для уменьшения сκοροсτи πορшня 4 шаρниρ 9Depending on the required operating conditions of the piston machine, the positions of the dead points of the piston 4 moving in return in cylinder 2 change, as a result of which the value of its stroke changes, and this makes it possible to regulate the working volume of cylinder 2 and the degree compression. The change in the positions of the dead points of the piston 4 is carried out by shifting the hinge 6 of the articulated connecting rod 5, which transforms the return-forward movement of the piston 4 into rotation of the output shaft 9, towards the axis Y-Y' of the cylinder 2 (in this case, the distance from the positions The distance between point 4 and the axis of the output shaft 9 decreases, i.e. The positions of the center points ΒΜΤι and ΗΜΤ-ι shift to the positions ΒΜΤ 2 and ΗΜΤ 2 ) and the return of the shaney 6 κ axis U-U' of cylinder 2 (in this case, the distribution of the positions of the checks The shaft 4 to the axis of the output shaft 9 increases, i.e. The positions of the markers ΒΜΤ 2 and ΗΜΤ 2 approach or return to the positions ΒΜ^ and ΗΜΤ-ι). The displacement of the joint 6 of the articulated connecting rod 5 from the Y-Y' axis of the cylinder 2 and its return to the Y-Y' axis occurs under the action of the lever 10, with one end acting on the joint 6, and with the other end, where its swing axis 11 is located, interacting with the drive (not shown). 8 In this case, when the piston 4 moves from the dead point, the axis 11 of the lever 10 swings with the help of the intermittent element 12 along the straight line X-X' from the fixed position, for example, at point "a" until its subsequent fixation, for example, at point “b”. In case of necessity to increase the value of the stroke of the piston 4 in comparison with the standard value H, during its movement the axis 11 of the swing of the lever 10 is moved from the fixed position at the point “a” to the fixed position at the point “ск” or at the point “e” (Fig. 5, 8, 9). To stop the piston 4 at the dead center (Fig. 4) with the output shaft 9 rotating, the axis 11 of the swing of the lever 10 is moved from the point "b" to the point "a" and vice versa. At the same time, the hinge 6 of the articulated connecting rod 5 is shifted from the point "η" to the point "d", i.e. return to the Y-U axis of cylinder 2 and the pinion of the output shaft 9 in the section οτ ΒΜΤ κ ΗΜΤ. At the end of the output shaft 9, in the section between the two, the shaft is shifted from point d to point “η”, i.e. shift from the Y-Y axis. In the case of using a piston machine as an internal combustion engine, stopping piston 4 in the VM allows combustion of fuel at a constant volume, which increases the completeness of its combustion and reduces heat transfer to the walls of cylinder 2. Installing piston 4 in the NMT improves the processes of blowing and filling cylinder 2 in a two-stroke engine. To increase the speed of piston 4, joint 6 of articulated connecting rod 5 is shifted from axis Y-Y', moving axis 11 of swing of lever 10 from point "a" to point "c" when piston 4 moves from BMT to HMT, and is returned to axis Y-Y', moving axis 11 of swing of lever 10 from point "c" at point “a” and movement 4 οτ ΗΜΤ κ ΒΜΤ (Fig. 11).

In the case of using a piston machine as an internal combustion engine, the compression ratio is changed due to the fact that the strokes of the working charge and its compression are carried out with different stroke values of the piston 4, fixing the axis 11 of the swing of the lever 10 at the points “a” and “ϊ” (Fig. 13). In order to achieve a more complete expansion of combustion products in the engine and thereby obtain additional power on the output shaft 9, as well as more complete combustion of fuel and a reduction in the toxicity of exhaust gases, it is advisable to use a increase the stroke value of piston 4, compared to the stroke value of piston 4 on the intake and compression strokes (Fig. 8, 9). In the case of using a piston machine as a pump for liquids or gases with the output shaft 9 stopped, the movement of the piston 4 is carried out due to the movement of the axis 11 of the swing of the lever 10, producing a working cycle. In this way, the efficiency of the piston machine increases.
