Abstract

trata-se de um pistão e um método de construção do mesmo. o pistão inclui uma coroa superior que tem uma superfície de combustão superior e uma coroa inferior que pende da mesma. a coroa inferior inclui um par de furos para pino, axialmente alinhados e lateralmente espaçados, configurados para a recepção de um pino de articulação. uma galeria de resfriamento externa anular substancialmente fechada é formada entre as coroas superior e inferior, em que um fundo de superfície da galeria de resfriamento é formado por um piso da coroa inferior. uma entrada de óleo e uma saída de óleo se estendem através do piso. a entrada de óleo inclui uma protuberância em formato toroidal reta que se estende para cima a partir do piso para dentro da galeria de resfriamento, em que a protuberância é formada como uma extrusão monolítica a partir do material do piso da coroa inferior.
