VEHICLE PNEUMATIC BRAKE SYSTEM Russian patent published in 2000 - IPC

FIELD: transport engineering; brake systems. SUBSTANCE: supply pipelines of control cock of energy accumulators and relay valve are interconnected and connected to outlet of two-line bypass valve whose first inlet is connected through emergency cock to supply main line before protection valve with resistance to bypassing, and second inlet is connected to outlet of bypass protection valve in energy accumulator circuit. Control pipeline of control cock is connected with control inlet of energy accumulator relay valve. Opening pressure of bypass valves of operating brakes, energy accumulators and consumers circuits is either equal to or greater than energy accumulator release pressure. Bypass valve of energy accumulator circuit is made to provide reverse bypassing of air to pressure of commencement of operation of energy accumulators. EFFECT: reduced time required for release of spring energy accumulators by compressor, reduced metal usage, enhanced reliability. 4 dwg
