FIELD OF THE INVENTION The invention relates to engine-making, namely to hydraulically driven internal combustion engines,

A hydraulically driven free piston internal combustion engine is known, comprising a cylinder with side covers, two groups of diesel and compression pistons, a gas distribution system and power supply. Both groups of pistons are combined into a single unit by means of a distribution sleeve, which encloses the cylinder, equipped with a partition, forming two combustion chambers with the ends of diesel pistons. In general, the design consists of a section of a two-piston, hydraulically controlled internal combustion engine operating on a diesel cycle.

One of the drawbacks of this design is the presence of a balanced inertial force arising during the reciprocating movement of its moving masses. In addition, there is no strict fixation of the extreme positions of the pistons and the distribution sleeve rigidly associated with them, which can lead to malfunction.

The purpose of the invention is to balance and ensure the stability of alternating cycles.

This goal is achieved by the fact that the engine has at least two sections mounted on a common frame, and gear racks meshed in diametrically opposite poles with a gear wheel whose geometrical axis is fixed relative to the frame and rigidly connected with gear wheels a leash located between the two limiters mounted on the frame.

Figure 1 shows the device, a general view; Figure 2 shows a lead with two limiters.

A hydraulically driven internal combustion engine contains double piston sections 1 and 2, their hydraulic drives 3 and 4. two-piece hydraulic motor 5, toothed rails 6 and 7 rigidly connected to external distribution sleeves 8 and 9, respectively sections 1 and 2. t in engagement with gear 10. whose axis is located in support 11. Sections 1.2 and support 11 are mounted on a common frame 12. A gear 13 is rigidly connected to gear 10, and stops 14 and 15 are located on support 11,

The engine works as follows.

With a cycle of diesel in each

from sections 1 and 2, sleeves 8 and 9 make reciprocating movements, and since they are meshed with diametrically opposite poles with common gear 10 through gear racks 6 and 7, these movements

(sleeves) will be in phase. In this case, the inertial forces arising in each of the sections are balanced by the inertial numbers of the opposite section. The presence of stops 14 and 15 protects the engine from separation, i.e. uncontrolled increase in the degree of compression and temperature of combustion, at which the burnout of the pistons is possible.
