The utility model relates to engine building, namely to piston-type internal piston-type internal combustion engines that use driven devices to perform useful work, for example, for TpaHcnqmoiix drives q) components, in particular aircraft, for supplying liquid or gas to the consumer, as well as for generating electricity.

A well-known internal combustion engine, containing housing, opposed working cylinders, pistons installed in cylinders and interconnected by rods with sliders, two cranks, coaxially and opposite mounted in the housing, a synchronizing shaft kinematically connecting the cranks, crankshaft with working, driving and supporting end necks, and at least one driven device, connected by a rod with a slider to the drive neck of the crankshaft, the crankshaft being mounted in its eccentric journals the crank holes, and the piston rods are connected to the crankshaft working necks, while the longitudinal axis of the drive shaft of the driven device is perpendicular to the plane passing through the longitudinal axis of the rods connected to the pistons of the working cylinders (see patent of the Russian Federation No. 2062340, MKI6 F 02B 75 / 32, 1996).

The disadvantage of such an engine is poor balance due to the fact that the drive neck of the driven device is placed cantilever relative to the working necks.

The objective of this utility model is to improve the balance of a rodless internal combustion engine together with a driven device.

The task is achieved in that the internal combustion engine, comprising a housing, a pair of opposed working cylinders, pistons mounted in cylinders and interconnected by rods with sliders, two pivots, coaxially and oppositely mounted in the housing, a synchronizing shaft kinematically connected with the cranks, a crankshaft, with working, driving and supporting end necks, and at least one driven device connected by a rod with a slider to the driving neck of the crankshaft, the crankshaft being its own bearings and the necks are mounted in the exceitric openings of the cranks, the rods of the working pistons are connected with the working necks of the crankshaft, and the longitudinal axis of the rod of the driven device is perpendicular to the plane passing through the longitudinal axis of the rods connected to the pistons of the working cylinders, while, according to a utility model, the crankshaft is made of at least one group of necks, including two working necks and one drive neck, placed

between two working necks.

In addition, the task can be solved by the fact that the driven device can be placed symmetrically with respect to the longitudinal plane of the engine and can be made in the form of a reciprocating compressor, or a reciprocating pump, or a linear electric generator.

The search did not reveal among devices of the same destination

similar rodless engine with the above set of design features, which allows us to conclude that the inventive device meets the criterion of "novelty.

The essence of the utility model is illustrated by drawings, which:

in FIG. 1 shows a longitudinal section through an engine;

FIG. 2 shows a section AA of FIG. 1.

The internal combustion engine, made in accordance with the claimed utility model, comprises a housing, pairs of opposed working cylinders 1, pistons 2 mounted in cylinders 1 and interconnected by rods 3

(figure 2) with the sliders 4. Two 1 fivoship 5 (figure 1), coaxially and oppositio installed

by means of gears 7 n 8. The crankshaft 9 has at least one

a group of necks, including two working necks 10 and one drive neck

11, placed between two working necks 10. At least one

driven device 12 (figure 2) is connected by a rod 3 with a slider 4 (figL) with

the drive neck 11 of the crankshaft 9. The crankshaft 9 is its supporting

end necks 14 installed in the eccentric holes of the cranks 5.

The rods 3 of the working pistons 2 are connected with the working necks 10 of the crankshaft 9.

The longitudinal axis 15 (Fig. 15) of the rod 13 of the driven device is perpendicular

plane BB passing through the longitudinal axis 16 of the rods 3 associated with

pistons 2 working switchboards 1.

The internal combustion engine, made according to the claimed utility model, operates as follows. In the cavity of the working cylinders 1

nociynaer is a worker, as a result of the combustion of which the first pistons 2 move and the torque 1 is transmitted through the working necks 10 to the crankshaft 9 and cranks 5 kinematically connected by means of the synchronizing shaft 6. Moreover, the working necks 10 and the driving journal 11 provide the rods 3, 13 and Slider 4 is strictly reciprocating. The rod 13 and the slider 4 drive the driven device 12,

which can be performed, for example, in the form of a compressor for supplying gas

environment to the consumer and / or into the engine (air, gaseous fuel, etc.). The driven device can be made, for example, in the form of a pump for supplying liquid to the consumer and / or into the engine (fuel, oil, coolant, etc.). A driven device may also be implemented, for example,

and in the form of an electric generator for supplying electricity to the consumer and / or

engine (for example, in the ignition system) ..
