Title:
ブレーキ制御弁装置
Document Type and Number:
Japanese Patent JP7387723
Kind Code:
B2
Abstract:
A brake control valve arrangement for controlling application of a braking force comprises an electropneumatic brake control valve block (8) comprising a pressure controller with a hold valve and a vent valve, a main regulator valve (relay valve 9), an emergency regulator (15) and a variable load control pressure regulator (16). The valve block (8) has an inlet (2) for a brake supply pressure, and an outlet (3,4) in pneumatic connection with at least one brake cylinder. A pilot pressure into the main regulator valve (9) from the variable load control pressure regulator (16) is controlled by a solenoid valve (17). The solenoid valve (17) is adapted to vent the main regulator valve control pressure to atmosphere when de-energised, thereby enabling release of the braking force of the brake cylinder via the main regulator valve (9).
