Abstract

"êMBOLO DE VáRIAS PARTES PARA UM MOTOR DE COMBUSTãO INTERNA". A invenção refere-se a um êmbolo de várias partes (1) para um motor de combustão interna, com uma parte superior (2) que está ligada com uma parte inferior (3) através de uma ligação de parafuso. A ligação de parafuso é constituída de um ressalto de ligação (24), de forma tubular, feito no lado inferior da parte superior do êmbolo (2) com uma rosca externa (25), de uma cápsula intermediária (27) com uma rosca situada interna (28) e uma rosca situada externa (29), e de uma nervura de suporte (12) moldada na parte inferior (3) do êmbolo (1) com uma rosca interna (26). Neste caso, a parte superior (2) pode ser aparafusada com a parte inferior (3) através do ressalto de ligação (24), da cápsula intermediária (27) e da nervura de suporte (12). Neste caso, a cápsula intermediária (27) atua como corpo de compressão, e o ressalto de ligação (24) atua como corpo de dilatação, pelo que é produzida a tensão mecânica necessária para a fixação da ligação de parafuso.
