Abstract

sistema de lubrificacão para motor de quatro tempos portátil trata-se de um sistema de lubrificação para um motor de quatro tempos portátil que inclui uma extremidade de abertura da passagem de respiração que fica disposta substancialmente em um centro de uma câmara de operação de válvula, e a câmara de operação de válvula é formada afixando uma tampa de câmara de operação de válvula. uma tampa interna é afixada a uma superfície interna da tampa de câmara de operação de válvula a fim de ser fornecida ao longo de e em contato com a superfície interna da tampa de câmara de operação de válvula. uma passagem de sucção é formada como um vão entre a borda circunferencial da porção de placa de topo e a tampa interna. três ou mais tubos de sucção que estão em comunicação com a passagem de sucção são fornecidos na tampa interna, sendo que cada um dos tubos de sucção tem uma extremidade de abertura. pelo menos uma das extremidades de abertura dos tubos de sucção é fornecida mais baixa do que a extremidade de abertura da passagem de respiração em uma postura do motor durante o uso.
