发明名称 PISTÃO PARA MOTOR DE COMBUSTÃO INTERNA E MÉTODO PARA A FABRICAÇÃO DE UM PISTÃO DESTE TIPO
摘要 <p>The invention relates to a piston 1 for an internal-combustion engine made up of a first part and a second part, one of the two parts forming the piston head 4 and the other part forming the piston skirt 7 and a cooling chamber 20, which is delimited by material of the first part and by material of the second part, being configured in the piston 1. To enable a cost-effectively manufacture and maximum design freedom such piston for internal-combustion engines is in accordance with the characterised in that the two parts are joined together positively and non-positively via a press fit formed by a projection 28,29 of the second part, the projection 28,29 engaging with a recess 24,26 in the first part.</p>
