Abstract

An internal combustion engine having a piston ring (28) and a cylinder running surface formed with lubrication openings (20). The running surface (34) of the piston ring (28) is formed with at least one recess (43) extending in the axial direction of the piston ring (28) as far as its end face on the cylinder head side, the recess having on the crankshaft side a boundary edge extending in the running surface (34) at an inclination to the peripheral direction. <IMAGE>

Description

 1304753

The reading edge extending into the work through the groove 24, after which the lubricating hole 5 is located through the sensing surface of the ring, and is distributed obliquely to the upper end of the latter. In the direction of the lubricant, the gas passes through channel 25, then the circumference is accelerated. 1z. pf-ly, 8il.

Because the acquisition refers to the machine. structure, namely, engine building, and can be used in internal combustion engines.

The chain of the invention is to reduce the lubricant consumption by uniformly distributing the oil around the circumference.

Fig. 1 shows a cylinder for an internal combustion piston engine with a piston located therein, provided with piston rings, a longitudinal section; FIG. 2 shows a section of the piston ring of FIG. 1 (enlarged), frontal view; on fig.Z - the same, type in the plan; figure 4 - section of the piston ring, provided with an annular groove; figure 5 is the same, the view in the plan; figure 6 - section of the piston ring with an inclined annular groove, front view; FIG. 7 is a section A-A in FIG. 4; on Fig - section bb in Fig, 6,

The cylinder 1 (FIG. 1) of a two-stroke diesel engine, for example, for operation on ships, is equipped with exhaust 2 and exhaust 3 apertures and has lubricating apertures 5 on the inner wall 4, In the cylinder 1 a piston 6 is placed rings B, as well as rings 9, 10, P with notches 12, annular grooves 13 and channels 14, Rings 9 and 10 are fitted with a lock 1

On the working surface 16 of the ring 9 from the side of its upper end 17 there is made at least one EB) 1 12, and its lower limiting edge 18, extending onto the working surface 16, is inclined but towards the upper end 17,

The recess 12 has a flat inclined surface 19, which, according to FIG. 7, extends towards the upper end 17 at an angle oi, which lies within the limits of .9Q.

The piston ring 10 (Figs. 4, 5) has a groove 13 extending along its circumference and is provided with channels 14 that are perpendicular to the circumference and between which recesses 20 extend. The groove 13 has a semicircle cross section.

The compression ring 11 (FIGS. 6, 8) has, as a lock 2, protrusions 22 and 23 which are included in each other as a lock 2. In this ring there is a groove 24 in the form of a helical line ending in front of the lock 21, with the passage going downward The upper end 17 channels 25 are included in the groove 24. As in ring 10, grooves 26 pass between the channels 25, the lower limiting edge 27 in this case has the same direction as the groove 24, notch 26 (FIG. 8) has in this case, the concave shape 28, while the groove has a triangular cross-section.

For an example of the operation of a piston engine of an internal combustion, it is assumed that the piston 6 under the influence of gas pressure moves from its position to the dead center in the direction of the cylinder head; 27 and the schematically shown lubrication hole 5 coincides with the groove 24. According to the arrows, the gas flows through the channel 25, respectively, through the groove 24, after which the gas flows through cm dressing the hole 5 and the distribution of the lubricating oil is accelerated in the direction of the circumference. Additionally, channels 25 are clamped to equalize pressure in conjunction with groove 24.
