ELECTROPNEUMATIC VALVE MEMBER OF RAILWAY VEHICLE ANTISKID CONTROL DEVICE Russian patent published in 1997 - IPC

FIELD: railway transport. SUBSTANCE: electropneumatic valve member has housing 1, electromagnetic overlapping valve 6 and electromagnetic discharge valve 7. Movable partition 2 with valve 3 and movable partition 4 with valve 5 are secured in housing 1. Valve 6 has valve space 8, valve 9, valve 11 and atmospheric hole 10. Valve 11 overlaps channel 12. Channel 13 is connected with air distributor and channel 12. Space 14 above partition 2 is connected with valve space 8. Space 16 under partition 2 is coupled by channel 13 with air distributor. Valve 3 overlaps channel 17. Space 18 under partition 4 communicates with channel 17 and, through channel 19, with brake cylinder. Valve 7 has valve space 20, valve 22 and atmospheric hole 21. Channel 23 is overlapped by channel 22. Channel 23 connects space 24 above partition 4 with valve space 20. Restrictor 25 couples space 24 with channel 17. Valve 5 overlaps atmospheric channel 26. Spring 27 acts onto partition 2. Spring 28 acts onto partition 4. EFFECT: provision of quick release of pressure in brake cylinders at wheelset skidding. 1 dwg
