Abstract

é fornecido um pistão sem galeria que tem temperatura reduzida durante a operação em um motor. o pistão inclui uma parede superior com uma superfície de subcoroa exposta. uma cinta de anel e saliências de pino são dependentes da parede superior, e um par de painéis de saia depende da cinta de anel e é acoplado às saliências dos pinos por escoras. o pistão inclui uma região de subcoroa interior e bolsos exteriores que se estendem ao longo da superfície de subcoroa. a região de subcoroa interior é circundada pelos painéis da saia, pelas escoras e pelas saliências de pino. cada bolso exterior é circundado por uma das saliências de pino, uma porção da cinta de anel e as escoras adjacentes a uma saliência de pino. uma pluralidade de orifícios se estende através das saliências de pino e/ou das escoras desde a região de subcoroa interior para um dos bolsos exteriores para transportar óleo de resfriamento da região de subcoroa interior para os bolsos exteriores.
