The latter has at least one annular groove on the outer surface for an additional split ring. The inner ring can also be made of a composite of two elements arranged one below the other, the lower one of which is split, and the upper one made of a wear-resistant material.

FIG. I shows the proposed engine with two concentric zones of compaction, cross section; in fig. 2 - the same, in a longitudinal section; on fng. 3.- embodiment of the engine with an eccentric arrangement of the external seal; Fig. 4 shows an embodiment of sealing rings provided with a wavy spring; in fig. 5 shows the construction of the inner ring with additional outer rings; in fig. 6 shows the arrangement of two rings in one slot.

Internal combustion engine I (Fig. I and 2). contains at least two working cylinders 2 with pistons 3 placed in a drum-type block 4, a rotating cylinder head 5 with inlet 6 and exhaust (not shown) holes. The sealing ring is made in the form of two split rings: internal 7 and the outer 8, installed in the grooves 9 and 10 around the working cylinders so that the outer rings of adjacent cylinders contact one another over the surface 1. The outer ring 8 may be located eccentrically relative to the working cylinder (Phn. 3), and under the inner ring yl external fell nntelnymi rings may be placed wavy spring 12 for prnzhati them to the head (VNG. 4).

In one of the engine variants (Fig. 5), the inner ring 7 is placed in the recess 13 adjacent to the surface of the working cylinder 2 (concentric with respect to the latter), and has i; a outer surface 14, at least one annular groove 15 for additional split ring 16, and the other (Fig. 6) is made up of two rings 17 and 18 arranged one above the other, the lower one of which is split, and the upper one is made of a wear-resistant material that prevents wear of the surface interacting with the cylinder head. NII.

The engine works as follows.

The cylinder head 5 of the engine I rotates and sequentially connects the operator to the cylinders 2 of the block 4 having pistons 3,

with inlet G or outlet and ports.

Internal y-rings 7 in grooves x 9, made split n spring-loaded 12, moving, for example, in notch 13 adjacent to the surface of the cylinder, prevents yTe4ky gas or due to the presence of additional pg-cut rings 16 located in the grooves 15 outer surface 14, or by means of rings 17 and 18, located one above the other.

The outer sealing rings 8, installed in the grooves 10, interact with each other over the surface I and create, together with the inner rings, a labyrinth sealing zone that prevents the leakage of gas from the combustion chambers. Thus, the tightness of the engine and its overall efficiency are significantly improved.
