Abstract
PURPOSE: To load a brake with minimal brake power required and thus improve its durability, by reducing the air pressure fed from a pressure source to the brake through a decompression device fitted to an emergency braking line.
CONSTITUTION: When the pressure (PE) in an emergency line 2 is reduced below a preset level and a relay emergency valve 5 is opened, the down and upstream pressure of a limiting and quick valve 8 are equalized because of an inlet port 16. But when the discharge pressure of the valve 5 increases above the preset level, a plunger 11 is lifted and its inner wall is pressed to the upper spherical end of a valve stem 14 to close the inlet port 16. then the air pressure fed in an air chamber 7 is reduced at a certain rate. By appropriately setting the ratios of pressure receving areas S1, S3 of the plunger 11, the pressure fed in the air chamber 7 is reduced when the pressure PE drops and especially when the pressure is released to the atmospheric air through separation of the tractor, which can improve the durability of the brake.
