Abstract

resumo patente de invenção: “pistão construído em duas peças de uma máquina de combustão interna”. a invenção se refere a um pistão (1) de uma máquina de combustão interna, configurado como um pistão de canal de arrefecimento construído em duas peças, que compreende um corpo de base (2) e um elemento de anel (3). o elemento de anel (3) que apresenta uma zona de anel (18), bem como uma zona de fogo (17) abrange do lado externo um canal de arrefecimento (15), que do lado interno é delimitado por uma parede intermediária (16), que separa o canal de arrefecimento (15) de um recesso da câmara de combustão (12) montado na cabeça do pistão (10) do corpo de base (2). o corpo de base (2) e o elemento de anel (3) juntos formam duas superfícies de separação (4a, 5a) circunferenciais, deslocadas uma em relação à outra, para cuja finalidade, em cada caso, duas mantas de união cooperantes (6a, 6b; 7a, 7b) do elemento de anel (3) e do corpo de base (2) estão ligadas de forma coesa.
