Abstract

é provido um pistão de aço sem galeria para um motor de combustão interna. o pistão compreende uma superfície com coroamento inferior exposta, uma correia anular com ranhuras anulares, saliências de pino, painéis de saia, e suportes. o pistão inclui adicionalmente uma região com coroamento inferior interna e bolsas externas se estendendo ao longo da superfície com coroamento inferior. a região com coroamento inferior interna é circundada pelos painéis de saia, os suportes, e as saliências de pino, e cada bolsa externa é circundada por uma porção da correia anular e uma das saliências de pino, e duas dos suportes. o pistão inclui uma pluralidade de fendas de óleo que se estendem através da parede traseira de uma das ranhuras anulares, tipicamente a terceira ranhura anular, até a região com coroamento inferior interna e/ou das bolsas externas para permitir drenagem de óleo de resfriamento. cada fenda de óleo tipicamente tem um diâmetro variando de 30% a 100% de uma largura axial da ranhura anular.
