Abstract

PISTãO RESFRIADO POR LUBRIFICANTE E COM LUBRIFICAçAO DO PINO DO EMBOLO. E descrito um pistão para um motor de combustão interna, o motor tendo uma biela acoplada em um pino do êmbolo, o pino do êmbolo sendo conectado no pistão para movimento pivó em torno de um eixo geométrico, o pistão compreendendo: uma parte de topo e uma parte de parede de forma no geral cilíndrica que estende-se a partir da parte de topo, as partes de topo e de parede definido uma cavidade tipo saia, a parte de topo com uma projeção que estende-se para baixo com uma superfície de apoio voltada para baixo para o pino do êmbolo, a superfície de apoio estendendo-se na direção do eixo geométrico e definindo uma parte de um cilindro centralizada no eixo geométrico, e a projeção com lados opostos voltados para a cavidade tipo saia, pelo menos uma passagem de lubrificante que estende-se através da projeção de um dos lados opostos e sobre a superfície de apoio até o outro dos lados opostos, e uma abertura de lubrificante comunicando entre a passagem de lubrificante e a superfície de apoio para suprir lubrificante à superfície de apoio e ao pino do êmbolo.
