RAILWAY CAR BRAKES Russian patent published in 2010 - IPC B60T13/26 B61H13/20 B60T17/06 B61H11/02 

FIELD: transport.

SUBSTANCE: invention relates to railway vehicles, namely to car air-operated equipment. Said equipment comprises, braking main line, air control valve, standby tank and automatic operation device fitted on car frame. Standby tank case if made from diamagnetic. Said case accommodates piston made from magnetic material to reciprocate therein, furnished with check valve and interacting with magnetic slide arranged inside standby tank, made from diamagnetic and spring-loaded by compression spring. Aforesaid reservoir case communicates, on one side, with atmosphere and, on the other side, with bypass valves bodies accommodating pistons spring-loaded by compression springs. Said pistons incorporate sphere-shaped pressure-control valves spring-loaded by aforesaid springs. Note that said springs of pistons and valves feature different linear stiffness. Both spaces of bypass valve bodies communicate with atmosphere. Bypass valve bodies communicate with automatic operation device via pipelines. Automatic operation device consists of case representing cylinder with aligned grooves and plunger furnished with recess and thrust bearing. Said aligned channels communicate with bypass valve bodies and air control valve on one side, and, on the other side, with braking cylinder above-piston space.

EFFECT: simplified design, higher reliability.
