Description

Knife drivers operating on the principle of an internal combustion engine are known, the cylinder of which is fixed on the pile head with the help of a frame, and the striking part is connected to the piston of the cylinder.

The invention, related to such women, aims to improve their design and consists in the fact that longitudinal cuts are made in the piston rod, which connect the explosion chamber with the atmosphere when the piston is lifted for exhaust gases, and for the chamber purging are made cuts the inside of it.

The drawing shows a longitudinal section of the proposed Koprov women in schematic form.

The cylinder 7 of the head is fixed on the head of the pile 8 by means of the frame 16, which also serves as a guide for the striker 6, which is connected by a rod 5 to the piston 14. The frame 16 is fixed on the pile by means of a removable head cover 17 in which the gasket is laid 18 dl, solid wood.

The job of a woman is as follows. In the initial position, in the chamber 20 there is a combustible mixture, in the chamber 21 is atmospheric air. By a spark 10, a spark is given, the mixture explodes, and the piston 14 together with the striking part 6 rises up. Wherein

the air in chamber 21 is compressed to about three atmospheres, and as soon as the upper part of the notch 3 reaches the upper plane of the lower cylinder cover, the exhaust through this cutout begins. After further ascent to five to six centimeters, the piston is at the height of the notches 2, which at this moment inform the explosion chamber 20 s. Camera 21, from which the compressed air is distilled into the explosion chamber, blowing it through the cutout 5. Due to the acquired speed, the piston and the striking part move upwards, and when the upper plane of the piston reaches the upper edge of the notches 2, the chamber 21 is uncoupled from the blasting chamber 20. From this moment on, fresh air is sucked into the blasting chamber, and in the chamber 21 the air is compressed approximately five atmospheres and a portion thereof, under this pressure, will drive a carburetor / 5 of the valve 19. Further, valve 19 is closed and the piston compresses the air still further - to a pressure above five atmospheres. By that time, the speed of the piston and the impacting part is rapidly approaching zero, due to a decrease in manpower and an increase in air resistance compressed in chamber 21. At the highest position of the piston, its speed is zero, and the impacting part begins to fall.

During the fall into the chamber 21, air is sucked through the valve 7. In chamber 2 | 9, before the connection with the chamber 2 / occurs, the air is compressed and, after connecting, a part of the air flows into chamber 21. After the second separation, five to six centimeters in height, the combustible mixture is driven through the nozzle P, and then it proceeds from 1 step to about three atmospheres and the impact of part 6 of the pile. After about 0.1 seconds, a spark is given, and the process is repeated.

The run is performed as follows. There is pressure in the combustion chamber connected to the carburettor, the lifting mechanism lifts the impact part using a hook, not shown in the drawing, drops it, and the woman starts the work.

Since the woman works intermittently to rearrange the copra, install piles, etc., and the cylinder inside is blown with cold air, special cooling is not provided. But the cylinder can be cooled with bodies.

To supply the combustible mixture, a nozzle 9 is used, which is opened during the fall of the piston, by means of a protrusion on the bar 12, which is connected to the striking part. The protrusion strikes the crankshaft cam 11 opening the nozzle. The ignition is made from the magneto located at the bottom and giving a spark after 0.05-0-0 seconds after the impact of the woman on the pile.

The subject matter of the invention.

Koprova Baba, working on the principle of the engine. internal combustion, with a cylinder fixed on the pile head with a frame, and with an impacting part associated with the piston of the cylinder, characterized in that a longitudinal notch 3 is made on the piston rod for exhaust gas exhaust, connecting the explosion chamber 20 with the atmosphere when raising the piston, and for purging the chamber-cut-outs 2 on the inner side, the glass of the cylinder communicating the upper chamber 27 with the explosion chamber 20 upon further raising of the piston.
