Abstract

ARRANJO E MÉTODO DE ARREFECIMENTO DO CÁRTER DE UM COMPRESSOR LIVRE DE ÓLEO PARA UM VEÍCULO FERROVIÁRIO. A presente invenção se refere a um arranjo de arrefecimento do cárter de um compressor livre de óleo que inclui um compressor tendo um cárter, pelo menos um cilindro do pistão suportado no compressor tendo um cárter, um conjunto de cárter suportado pelo compressor tendo um cárter e ligado a um pistão do pelo menos um cilindro do pistão por uma haste de conexão, pelo menos uma válvula de entrada suportada em e em comunicação de fluido com o compressor tendo um cárter, e pelo menos uma válvula de saída suportada em e em comunicação de fluido com o compressor tendo um cárter. Um fluxo cruzado de arrefecimento de ar é estabelecido entre a pelo menos uma válvula de entrada e a pelo menos uma válvula de saída para resfriar o compressor tendo um cárter. A pelo menos uma válvula de entrada e a pelo menos uma válvula de saída include válvulas de segurança. Um primeiro bocal é posicionado na pelo menos uma válvula de entrada, e um segundo bocal é posicionado na pelo menos uma válvula de saída.ARRANGEMENT AND METHOD OF COOLING THE CRANKCASE OF AN OIL-FREE COMPRESSOR FOR A RAILWAY VEHICLE. The present invention relates to an oil-free compressor crankcase cooling arrangement comprising a compressor having a crankcase, at least one piston cylinder supported on the compressor having a crankcase, a crankcase assembly supported by the compressor having a crankcase and connected to a piston of the at least one piston cylinder by a connecting rod, at least one inlet valve supported in and in fluid communication with the compressor having a crankcase, and at least one outlet valve supported in and in fluid communication fluid with the compressor having a crankcase. An air cooling cross flow is established between the at least one inlet valve and the at least one outlet valve to cool the compressor having a crankcase. The at least one inlet valve and the at least one outlet valve include safety valves. A first nozzle is positioned on the at least one inlet valve, and a second nozzle is positioned on the at least one outlet valve.
