SU77315A1 - Matrosov air distributor - Google Patents

Description

A step-down active brake on flat profiles, where the brake cannot be exhausted, and difficult to use short-flow tempering, does not have sufficient control over the slow release processes, which is especially true for large leaks in the train's braking network.

The proposed air distributor is intended to give a brake with a light stepless release while maintaining all the qualities of the operating brakes. For slow and steep descents, a switch to brake operation is introduced, similar to the exploited Matroso's brake.

In the diagram, the air distributor is shown in the position: tempering and charging.

Charging takes place as follows: compressed air from the line enters through channels 12 “J3 into the spool chamber and then through the opening M and the notch 15 into the reserve tank. At the same time, the working chamber is charged with air through the opening M, recess 15 I1 channels 16 and 17. The torus via the clear cylinder IB is in communication with the atmosphere through channels 5, 19, 20, 21, 22 and 23.

When the air pressure in the line goes down, the piston / with the gland 2 moves to the right, which causes the line to discharge, at which air through the return valve 10 and channels 34, 24, 25, 20, 19 and 1 enters the brake cylinder.

At the same time, discharging into the brake cylinder and the gold chamber through channels 19 and, 18 takes place.

When the pressure in the spool chamber decreases, Porschen 3 will go up and, using Klisy 4 and Frame 5, will move the gillet to 6 (to the right; the hole 25 will overlap and the air will not flow into the brake cylinder from the line. The reservoir of the brake cylinder will then be established , 16.26, 27, 28, 29, 30, 20, 19 and 18. If the pressure drop in the line is stopped, the piston / moves to the left, the spool 2 will block the opening 19 and the piston 3 will stop. inhibitory qi The lindra will move to the right, compressing the spring 9, there will be no sweat spool 7 and the latter will block channel 27, which will set the braking level.

When braking and overlapping set message line

with a spare tank through the check valve W and channels 34, 24, 26, 16 and 15.

Full braking will occur after the piston 5 reaches the extreme upper position and the piston 8 moves fully to the right.

- If you raise the balance to master4} and .11, the jerk J will go to the leftmost position, and spool 2 will report 9 t9rmazhnoy ..,; a cylinder with atmosphere through channels (5, 19, 20, 21, 2). Air from the main pipe through channels 12. and 13 will begin to flow into the spool chamber, and piston 3 will go 1 down. But as the air pressure in the brake cylinder decreases more quickly than piston 3 goes down, the valve 7 under the action of "spring 9 will advance valve 6 and inform channel 26 of the spare tank with channels 27 and 28, but filling the brake cylinder with air does not will occur as channel 30 overlaps spool 2.

If, due to jamming or skipping, the piston / does not move to the tempering position, channel 30 will remain open and the brake cylinder will communicate with the atmosphere through channels 18, 19, 20, 30, 29, 28, 27, 31, 32 and 33.

At the end of the brake release, the piston 1 will necessarily move to the extreme release position, due to the fact that the spool chamber communicates with the brake cylinder through channels 35, 25, 20, 19 and 18 and there is a short-term sharp decrease in air pressure in the spool chamber. The piston 1 will move to the left under the action of air pressure in the line, the spool 2 will close the channel 25 and separate the spool chamber with the brake cylinder; the channel 30 is also derected and the communication of the brake cylinder with the atmosphere is established according to the diagram.

If by turning the cork // communicate with each other channels 28, 22, and 19, and channels 30 and 21 to block.

This will install the brake cylinder with the atmosphere only through the main spools. In this case, when braking, the air from the reserve tank will flow into the brake cylinder through channels 15, 16, 26, 27, 28, 22, 19 and 18, and when it is released, the brake cylinder will communicate with the atmosphere through channels 18, 19, 22, 28, 27, 31, 32 and 33, i.e. everything will happen as in a typical brake.

Claims (3)

1. The air distributor of the Matrosov system, characterized in that, in order to effect stepless tempering by the type of non-acting brakes, the main spool valve uses a channel that, when the main body is discharged, directly connects the brake cylinder to the atmosphere. 2. The air distributor according to claim 1, characterized in that, in order to make the transition to stepped tempering, it uses a switching valve, which in the stepped release position blocks the communication of the brake cylinder channel with the atmospheric channel of the main spool and opens the communication of the brake cylinder channel with the atmosphere through main and equalizing zolotniki for the production of holidays in a known manner. 3. Air distributor for pi. 1 and 2, characterized in that in order to install the switching valve to the stepless tempering position and to allow braking in a known manner by means of the main and equalizing spools in the main spool, a notch is used (Carrying out the braking channel during the brake position of the main body: groove main spool. -O L ///., //. 3 n j70-700; Y t 1a-gasppra / s
