COMPRESSOR GAS-DYNAMIC PRESSURE CHARGING SYSTEM Russian patent published in 2002 - IPC

FIELD: railway vehicles. SUBSTANCE: invention relates to systems increasing capacity of compressors installed in brake main lines with variable consumption of compressed air. Proposed gas-dynamic pressure charging system of compressor has intake pipeline in form of housing consisting of chamber connected with inlet device formed by contracting nozzle and chamber. Chamber accommodates pneumatic cylinder with spring-loaded piston dividing pneumatic cylinder into underpiston and overpiston spaces. Partition is movably secured on guides and is connected with tie-rod with spring-loaded piston. Control unit is connected by temperature transmitter with contracting nozzle and by pressure transmitter, with pressure source and also with valves. EFFECT: increased capacity of compressor owing to provision of swirling of sucker-in air and maintaining of reliable resonant pressure charging at variable climatic and weather conditions of operation. 2 dwg
