Abstract

1/1 resumo “pistão de aço com projeto de furo rebaixado” trata-se de pistão para um motor de combustão interna. o pistão inclui um corpo de pistão que é fabricado a partir de aço. o corpo de pistão tem uma porção de coroa com uma superfície de combustão superior, um par de saias que dependem da superfície de topo, um par de protuberâncias de pino para receber um pino de articulação e uma pluralidade de pontes de protuberância de pino que se estende a partir das protuberâncias de pino até as saias. cada uma das pontes de protuberância de pino se estende axialmente para uma extremidade inferior que é oposta à porção de coroa e tem uma nervura com uma espessura aumentada em sua extremidade inferior. pelo menos uma das pontes de protuberância de pino tem uma superfície de furo rebaixado geralmente plana para fornecer uma local de referência para a usinagem do corpo de pistão.
