Abstract

EMBOLO PARA UM MOTOR DE COMBUSTçO INTERNA. A presente invenção refere-se a um êmbolo (1) para um motor de combustão interna compreendendo um elemento de anel (6) fechado que é disposto na área periférica radialmente externa do fundo do êmbolo (5) e é unido ao corpo básico (4) do êmbolo através de uma cola altamente resistente ao calor, O corpo básico (4) é feito de alumínio forjado ao passo que o elemento de anel (6) é feito de Ni-resíst. Um canal de esfriamento (15) fechado com furos para a entrada e saída do óleo de refrigeração encontra-se entre o corpo básico (4) e o elemento de anel (6), o que fornece um êmbolo (1) com um design simples, que pode ser produzido a baixos custos e que pode ser submetido a altas cargas térmicas.
