Abstract

a presente invenção refere-se a um conjunto de pistão, pistão para o mesmo e métodos de construção. o conjunto inclui uma cabeça de pistão e uma haste de conexão operativamente acoplada à mesma através de um pino de articulação. a cabeça do pistão tem uma coroa superior com uma cuba de combustão e uma superfície sob a coroa. a coroa inferior inclui furos de pinos axialmente alinhados que recebem o pino de articulação. uma parede superior da coroa inferior tem uma entrada de óleo, uma saída de óleo e uma superfície de suporte de selim côncava que encosta-se ao pino de articulação. uma galeria de resfriamento externa em forma de toroide é formada entre partes de parede da coroa superior e coroa inferior, onde a galeria de resfriamento externa envolve uma galeria de resfriamento interna. a haste de conexão é fixada ao pino de articulação para oscilação conjunta. a haste de conexão tem uma passagem de óleo em comunicação de fluido com um furo passante no pino de articulação para permitir que o óleo flua através da mesma para a galeria de resfriamento interna através da entrada de óleo.
