SU41564A1 - Air distributor for automatic air brakes - Google Patents

Description

The air distributor proposed by the authors, equipped with two main, non-interconnected pistons, which control the sliding of each other by spools, is not significantly different from the well-known air distributor in the Matrosov brakes and, in particular, from the air distributor in the form of its execution, proposed by the Croatian.

Air throttling openings in air distributors are well known.

In FIG. 1 shows a section of the air distributor with an excitable piston 36, feed 4J and a jump valve 57; FIG. 2 is a cut of the whole distributor; FIG. 3 - top spool; FIG. 4 - bottom spool, FIG. 5 - mirror section; FIG. 6 - a mirror on top; FIG. 7 - upper face of the spool; FIG. 8 - lower face of the spool; FIG. 9 - piston rod with milled grooves and a spool 76.

The body of the JO distributor consists of two cylindrical Kame: p 11 VI 12 pistons 75, 14. The piston rod 13 consists of a tube 75,

the outer surface (having two milled grooves 54, which with the help of two balls in them rotate the spool 16. The rod 77. reinforced with a cover, keeps the piston from turning with the help of two or three studs passed through the rod 75 and soldered) passage of the shchi into the slot. The partition between cameras 77 and 72 serves as a landing mirror 76. There are in the mirror (Fig. 5, b hole 19 is the exit of the channel 79 (fig. I) hole 20 with a groove 27 leading to the spare tank, hole 21 for the channel exit and the hole 2. with a groove 24 communicating with the atmosphere. The hole 22 communicates with the opening 20 a groove which serves as an extension of the groove 25. The camera 1 communicates with the channel 22 through the hole 26 in the plug, not shown in the drawing. two holes of different section through which, under the influence of air pressure ds, when the reservoir is lowered, the pressure in the line is 1.2 at & all the air from chamber 11 flows out within 40 seconds for the deceleration commodity mode, and in 8-10 seconds in passenger mode.

The nick / 6 rotates the spool 27, which is implemented as follows: the piston rod / 4 has two grooves 28 on the outside for its direction through two balls (or dowels); inside the stem there are screw grooves; A tube pressed into the spool 27 has grooves 29 along the outer surface; when the piston / # moves vertically, the spool 27 is rotated. The top cover gives the direction to the rod 50 and has two chambers 37, 32. The loaded mode is carried out by air compression, namely the piston 14, reaching the top, will drive the air from chamber 12 to chamber 32, compress its up to 3, 6 atm. In the empty mode, through chamber 33 with chamber 32, chamber 31 is connected, and then the air pressed by the piston 14 will have a pressure of 2 atm. Air compression is possible to replace the springs under the condition of rotation of the spool 27 not by 90 °, but by 8-10 and accordingly the groove 34 (FIG. 4) will be lengthened, and the hole 35 will coincide with the groove. The casing of the chamber of the pivot 36 is integral with the casing 10 and is located so that the channels J9, 22 correspond to the mirror through which the spool 16 turns. In the channel 37, air penetrates from the additional tank. The brake is charged as follows. The air from the line through the nozzle 38 enters the chamber of the piston 36 and pushes it to the lid 39, channel 40 passes to the feed valve 41 and, raised in: it, enters the channel 42, which passes into the channel 22; the latter fits one end to the mirror, ending at hole 22 in it, and the other end to chamber 43. By channel, 22 through air 26, air enters chamber 7 /, the piston 13 is lowered and hole 44 enters an additional tank, which is connected by nozzle 45 through the channel 37, it fills the space behind the piston 36. The air passes from the channel 22 through the recess 23, which is covered by the recess 46 of the spool 27. The brake chamber 47, connected by a hole 48 to the brake cylinder, has an exit

to the atmosphere through a hole 49 in the zojjothhke 27, a hole 50 in the spool / b and a channel 19, which goes into the chamber of the jump valve 5 /, with the open position of which the chamber is in communication with the atmosphere. During deceleration, with a slow decrease in pressure in the line, the pressure will be equalized through the groove 52 in the guide rod of the jump valve 51. But with a rapid decrease in pressure, in the line by 0.4-0; 5 atm. with the piston 36, the jump valve closes the outflow into the atmosphere from the chamber and communicates it with the chamber 43, as a result of which the air from channel i 42, 22 and from the main through the raised valve 41 rushes through channel 19 into the brake chamber 47; due to the pressure created in this chamber, the spool 27 rotates, and a decrease in pressure in the chamber // under the pressure of the additional reservoir will cause the piston 13 to move upwards, which will cause the spool to turn 16. With a small volume of the brake cylinder, pressure builds up in it and the spool 27 will overtake the movement of the ash gland 16, covering the grooves 53 and 34, and part of the air from chamber 47 will be released into the atmosphere, as the spool 27 will override the movement of the spool 16 and the hole 35 will face the opening 58, which in turn will be set against 24 leading to the atmospheric opening 23. When valve 16 stepwise leave sdvinets back and povtorits described above, when the spool 27 is ahead of the movement of the spool 16, and part of the air released from the brake chamber to atmosphere.

The subject matter of the invention.

one

The design of the air distributor according to Matrosov's patent No. 6410 is different in that the pistons 14 and 13 that are not mechanically interconnected between themselves and which control the sliders 27, 16 that are rotatably sliding one over the other, moving in the bs direction, have helical grooves on their rods turning the spools 27, 16 interacting with these grooves sliders on the spool ;. to the dependent author's testimony of A.P.
