SU28864A1 - Dual Action Internal Combustion Engine - Google Patents

Description

Patent No. 10731 describes a dual-action internal combustion engine with an inserted working fluid. The lid inserted inside the sleeve rests on the collar in the sleeve and is attached to the last cylinder jacket by means of a bayonet with squeezing bolts. In order to simplify the design and the ability to firmly pull back the lid, not loosening it with heavy screw or bolt connections, and not to increase In addition, in the proposed modification, a spring ring is inserted into the sharpening of the cylinder head, which is placed in the recess of the tension ring and uzhit support for the latter; when the tension ring is displaced in the axial direction, the cylinder bushing presses against the wall of the cylinder of the cylinder and holds the cover in a fixed position ...

The drawing shows a vertical section of a dual-action internal combustion engine.

A working cylinder sleeve 3, representing an independent body, is inserted into the body of the jacket 7 of the cylinder. A lid covering the working space 3 of the cylinder 3 from above is inserted from the inside, i.e. from the side of the piston 5 and is supported by part 6 on the protrusion 7 of the cylinder sleeve 2 located in the cylinder head. In the case of the cylinder jacket there is a tensioning device consisting of a tension ring 9 rearranged by screws 10 in the direction of the axis and secured by nuts 11. This tensioning ring holds the lid between the protrusion 7 and the spring ring, inserted into the sharpening 76 of the lid 4 and serving as a support for the ring 9.

When the lid is fitted, the ring 8, which is springing up due to the slot 72 therein, is inserted into the recess 16 of the lid thereafter, so the lid is set to the position shown in the drawing. Following this, by tightening the screws 10 evenly, which are in the proper quantity, the tension ring 9 rises from the surface 13 until it is pressed into the spring ring 8. When the ring 9 of the cylinder is tightened, the sleeve 2 is pressed against the wall of the jacket body.

When the lid is to be removed, the pressure exerted on the pressure ring 9 by the screws 10 is reduced, as a result of which the ring lies on the surface 13. Then the lid 4 is suspended or fixed using a device that is not shown in the drawing (for example, a crane), after which you can release the spring ring 8 and slide the cover down. Instead of ring 8, you can, of course, apply several tilted bodies that perceive tension pressure

rings P, instead of which several divided bodies can also be used. Finally, with a small cap, it is possible to strengthen the latter with a ring P only by screwing.

The same reinforcement of the cover can be applied on the underside of the cylinder, and with appropriate changes for the heads of such cylinders that do not have a separate cylinder insert bushing.

The subject of the patent.

Modification of the dual-action internal combustion engine according to patent no. 10731, characterized by the use of a spring ring 8 inserted into the sharpening of the cylinder cover, which serves as a support for the tension ring 9, provided with a recess for the ring 8.
