Abstract

sistema de lubrificação para motor quatro tempos.trata-se de um sistema de lubrificação para um motor de quatro ciclos que lubrifica o mecanismo de válvula com a névoa de óleo da concentração reduzida pelos meios de liquefação. o sistema de lubrificação tem uma passagem de alimentação de óleo para conectar um reservatório de óleo e a câmara da manivela e enviar o óleo retido em forma liquida no reservatório de óleo à câmara da manivela sob uma pressão negativa da câmara da manivela, em que a passagem de comunicação para conectar a câmara da manivela e o reservatório de óleo e enviar névoa de óleo gerada na câmara da manivela para o reservatório de óleo quando sob uma pressão positiva da câmara da manivela, em que os meios de liquefação no reservatório de óleo para liquefazer a névoa de óleo enviada a partir da passagem de comunicação para o reservatório de óleo para diminuir a concentração da névoa de óleo, e em que a passagem de fornecimento para fornecer a névoa de óleo a partir do reservatório de óleo para a câmara de operação por válvula através dos meios de liquefação.
