Abstract

PISTçO DE DUAS SEÇÕES PARA MOTOR DE COMBUSTçO. É proposto um pistão de duas seções para motor de combustão que consiste de uma seção superior do pistão (2) e de uma seção inferior do pistão (2). No fado inferior da seção superior do pistão (2), afastado em relação ao fundo do pistão, está disposta uma perfilação (24) cilíndrica em posição coaxial para com o eixo do pistão (15), em cuja extremidade afastada do fundo do pistão estão perfiladas duas saliências (27) direcionadas em sentido radial para o exterior e tendo formato de gancho. A seção inferior do pistão (6) apresenta no lado do fundo do pistão uma abertura (16), na qual serão introduzidas na montagem da seção superior do pistão (2) sobre a seção inferior do pistão (6) a perfilação cilíndrica (24) com as saliências (27), sendo girado de maneira que as saliências (27) posicionam-se por trás da borda da abertura (16).
