Description

В предлагаемом поршне дл  воздушных и иных насосов и двигателей, с целью получени  плотного соприкасани  со стенками цилиндра, в качестве набивки применена ртуть.In the proposed piston, for air and other pumps and engines, in order to obtain a tight contact with the cylinder walls, mercury was used as a gasket.

На чертеже фиг. 1 изображает вертикальный разрез цилиндра с поршнем; фиг. 2 - вид поршн  сверху и фиг. 3 - разрез поршн  по линии АВ на фиг. 1.In FIG. 1 shows a vertical section through a cylinder with a piston; FIG. 2 shows the piston from above and FIG. 3 is a section through the piston along the line AB in FIG. one.

Поршень состоит из штока С, на который навинчена и укреплена винтом г муфта Al с трем  дисками а, образующими две полости 0; кра  дисков скошены под углом в 30° дл  уменьшени  трени  между поршнем и стенками цилиндра А. Верхний диск снабжен отверстием, закрываемым винтовой пробкой К и через которое полости О наполн ютс  ртутью. Отверстие в крышке d цилиндра N, через которое проходит шток С, вместо применени  сальника, также уплотн етс  ртлтью, наливаемой в чашку Ь, имеющуюс  на крышке d и закрываемую крышкой Ъ.The piston consists of a rod C, on which an Al coupling with three disks a is screwed and fixed with a screw g, forming two cavities 0; the edges of the discs are beveled at an angle of 30 ° to reduce friction between the piston and the walls of cylinder A. The upper disc is provided with a hole that can be closed with a screw cap K and through which the cavities O are filled with mercury. The hole in the lid d of the cylinder N, through which the rod C passes, instead of using the stuffing box, is also sealed with an orifice poured into the cup b, which is on the lid d and is closed by the lid b.

Перед заполнением полостей О ртутью, внутренние стенки цилиндра и поршень со штоком амальгамируютс , дл  чего их предварительно промывают 10%-ным раствором серной кислоты. Нижний диск имеет выпуклую наружную поверхность, что .может иметь значение в случае расположени  клапанов на дне цилиндра.Before filling the cavities with mercury, the inner walls of the cylinder and the piston with the rod are amalgamated, for which they are pre-washed with a 10% solution of sulfuric acid. The lower disc has a convex outer surface, which can be important if the valves are located at the bottom of the cylinder.

ПРЕДМЕТ ПАТЕНТ..SUBJECT MATTER ..

Поршень дл  воздушных и иных насосов и двигателей, характеризующийс  применениедт двух кольцевых полостей , образуемых трем  дисками а со скошенными кромками, заполн емых через Винтовую пробку К ртутью - с целью надлежащего уплотнени  с прикасающимис  внутренними стенками цилиндра А , амальгамИрованнымиA piston for air and other pumps and engines, characterized by the use of two annular cavities formed by three discs a with beveled edges filled through a screw plug. With mercury - for proper sealing with touching the inner walls of cylinder A, amalgamated

так же, как и сам поршень, снабженный амальгамированным штоком С, проход щим через отверстие в крышке d.цилиндра, уплотн емое ртутью, заполн ющею чашку ftj, .прикрываемую крышкою Ь.as well as the piston itself, equipped with an amalgamated rod C, passing through an opening in the cylinder head cover d. compacted with mercury, filling cup ftj, covered with cover b.
