Abstract

Invention m. used to remove condensate from the air receivers of the vehicle's braking system and improves the reliability of the trap. The central and radial channels 14 and 15 of the L-shaped piston 5 communicate the receiver 16 with a cumulative cavity (P) 12. The locking member is formed as an annular protrusion (KB) 8 on the lower surface of the piston, which interacts with the bottom 3. P 12 is enclosed between KB and the inner wall of the casing 1. Condensate that has accumulated in P 12 through the gap between the KB and the bottom is released with compressed air into P 13 and then into the atmosphere. When the pressure decreases in П 12 under the action of the spring 6 moves downwards and KB separates П 12 and 13. In the absence of pressure or flow of compressed gas in the system, condensate from P 12 is mechanically ejected by the lever 18 on the pusher 17, which raises the piston . 1 il. (L with

This invention relates to devices for removing condensate from pneumatic systems, for example, from air receivers of a brake system of vehicles.

The purpose of the invention is to increase reliability.

The drawing shows a steam trap for pneumatic systems of vehicles, a general view.

A steam trap for pneumatic systems of vehicles with a pressure regulator comprises a housing 1 with an outlet 2 in the bottom 3. Grooves 4 are additionally made in the inlet opening 2. In the housing 1, an L-shaped piston 5 with a spring 6 is placed. Nut 7 regulates the force developed by the spring 6 on the piston 5. On the bottom surface of the piston 5 there is an annular protrusion 8, which is a shut-off element of the exhaust valve that interacts with the sealing ring 9, which is a valve seat and installed in the bottom 3. Between the upper surface of the piston 5 and the housing 1 is a control cavity 10 connected to the pressure regulator 11. Between the annular protrusion 8 and the inner wall of the housing 1 there is a cumulative cavity 12, inside the protrusion 8 there is a drain cavity 13. The piston 5 has a central and radial channels 14 and 15, respectively, which communicate the receiver 16 with the cumulative cavity 12. In the outlet 2, a pusher 17 is installed for manual piston drive 5. To the outer surface of the bottom 3 is pivotally attached to the lever 18 connected to the pusher 1 7.

Condensate from receiver 16 through channels 14 and 15 flows into storage chamber 12. Compressed air from receiver 16 enters control cavity 10. Pressure in cavities 10 and 12 is set to equal. The piston 5 under the action of the spring 6 and the force developed due to the larger surface area of the piston 5 in the control cavity 10 or in the accumulation cavity 12 is in the lowest position. The annular protrusion 8 of the piston 5 is pressed against the ring 9, the cavity 12 is separated from the drain cavity 13.

When the regulator 11 is activated, the pressure in the cavity 10 drops, and the piston 5 under the influence of pressure in the cavity 12, equal to the pressure in the receiver 16, overcoming the force of the spring 6, rises upwards. The condensate accumulated in the cavity 12 through the gap between the protrusion 8 and the bottom 3 of the pressure, compressed air is ejected into the cavity 13 and through the slots 4 of the outlet

2 holes in the atmosphere. When the pressure in the cavity 12 decreases, the piston 5 moves downwards under the action of the spring b and the annular protrusion 8 separates the cavities 12 and 13. In the absence of

the system of pressure or flow of compressed gas, the release of condensate from the cavity 12 is carried out by operating the lever 18 on the pusher 17, which raises the piston 5.
