Abstract

ÊMBOLO DE DUAS PEÇAS PARA UM MOTOR DE COMBUSTçO INTERNA. A presente invenção apresenta um êmbolo (1) de duas peças para um motor de combustão interna compreendendo uma câmara de com- bustão (16) no fundo do êmbolo (13). Tal êmbolo (1) é composto pelo corpo principal (5) e pela parte superior (6) que é aparafusada ao corpo principal (5). A fim de que a pressão de combustão aja substancialmente sobre o cor- po principal (5) que tem uma grande resistência mecânica e resistência tér- mica relativamente à pressão que reina na câmara de combustão, a parte inferior da câmara de combustão (16) é moldada no corpo principal (5), a parte superior (6) possui uma configuração essençialmente anelar, e a parte superior (6) aumenta a câmara de combustão (16) na extremidade no fundo do êmbolo ao passo que a limita como um colar (19) em direção radialmente para fora.
