Description

The invention relates to an internal combustion engine in which the cylinders are placed in pairs - opposite to the shaft with the axes parallel to the latter and the movement is transmitted to the shaft from a hollow piston rod, the total length of every two opposite cylinders placed opposite to each other is mounted on a shaft with a die-free crypolar groove hollow piston rods are used to supply the working mixture to the cylinders.

In the proposed engine in each pair of cylinders, one and l; 1prdr is working and the other is pumping, and the cavity common to both porous is used as a receiver, equipped with valves on both end sides of the pistons.

In FIG. 1 shows a longitudinal section of the engine; and FIG. 2 - cross section of it.

Around the working shaft 7 there are eight pairs of cylinders 5 and ZG with pistons placed in them and 8 connected by hollow rods in pairs //. Pistons and 8 (working and pumping), equipped with exhaust valves P and intake / O. Hollow stem cavity // forms receiver f6 Mid length

Rods are provided with annular recesses for clamps (5) holding the rods in pairs, and to each collar is attached a finger 4, which enters an endless curvilinear groove 5 in the holder 2, which is fastened on the shaft to the shaft. In each bonded pair of rods, the working pistons arrive at different ends of the rod. The clamps / 2 are provided with lugs / 5, which enclose the guides f fixed to the casing / 5 of the engine.

When starting, it moved the working shaft with rotation by fastening the holder 2 with the walls of its groove 3 on the shaft and fastening the fingers 4 pistons front | In the following order: if, for example, the finger of the upper pistons (Fig. I) moves from left to right (Fig. I), then the Lower Finger moves in the opposite direction, i.e., to the right; while the upper and lower fingers reach their dead spots, the fingers of the side pieces will be in the middle of the sleeve. The same movement of the fingers and pistons occurs when the engine is running. It has been stated above that the working pistons come at different ends of two coupled rods. Therefore, while the working piston of a single rod compresses the working mixture in its cylinder for an explosion, the PUMP piston of the rod coupled with it, also compressing the sucked mixture in its cylinder, passes it through its inlet valve fO inside the matching rsiera / b, from which A mixture with a force of 2-3 atmospheres will burst through the exhaust valve 9 into the working chamber of the cylinder at the opposite end of the piston, as soon as the gas pressure in this chamber is less than in the f6 receiver. The explosions of the working mixture will alternate and at each quarter of the shaft rotation will push two diametrically opposite pistons in two different directions.

The movement of the pistons through the fingers 4 and the holder 2 with a curved groove 3 causes the working shaft / in rotation.

The subject matter of the invention.

An internal combustion engine with cylinders arranged oppositely to each other around the shaft with parallel arrangement of axles and transferring movement of the shaft from a common for each two oppositely placed cylinders of a hollow piston rod through a cage mounted on the shaft with an endless curved groove, as piston rods used for supplying the working mixture to the cylinders, characterized in that in each pair of cylinders arranged in one line, one is the working cylinder, and the other is pumping Using common to both pistons cavity as receiver snabzheiiogo on both end sides valves at the bottoms porschiey:
