BRAKE SYSTEM OF RAIL VEHICLE Russian patent published in 1994 - IPC

FIELD: traction rolling stock. SUBSTANCE: pneumatic circuit has brake valve 1, auxiliary brake valve 2 communicating through interlocking device 3 with supply main 4, brake main 5 and auxiliary brake main 6. Air distributor 7 communicates through control input with brake main 5, through supply branch, with standby reservoir 8, and through output branch, with pulse main 9 of auxiliary brake valve 2. Maximum pressure valve 10 places supply main 4 in communication with input 11 of electric interlock valve 12 whose control branch 13 communicates with brake main 5 and output 14, with one of inputs of change-over valve 15. Second input of change-over valve 15 communicates with auxiliary brake main 6, and output 16, with brake cylinder circuit. Coil 17 of electric interlock valve 12 gets excited from contact element coupled with shaft of handle 18 of interlocking device 3 when the latter is cut in. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
