Abstract

"CONJUNTO DE PISTãO PARA MOTOR DE COMBUSTãO INTERNA". Trata-se de um mecanismo para vedar intervalos entre um conjunto de pistão e um cilindro para um motor de combustão interna. Um membro de vedação é inserido em uma parede superior de uma ranhura, que retém o anel de óleo de modo, para bloquear um intervalo entre eles. O anel de óleo tem dois trilhos em sua periferia externa. O trilho superior é radialmente maior do que o trilho inferior e se conforma melhor à forma do cilindro. O anel de óleo tem um recesso em sua periferia interna para manter um membro de compressão, que força o anel de óleo de encontro ao cilindro. O recesso é estendido além do membro de compressão, para proporcionar uma maior área de contato entre o anel de óleo e a ranhura."INTERNAL COMBUSTION ENGINE PISTON ASSEMBLY". It is a mechanism for sealing gaps between a piston assembly and a cylinder for an internal combustion engine. A sealing member is inserted into an upper wall of a slot, which retains the oil ring so as to block a gap between them. The oil ring has two rails on its outer periphery. The upper rail is radially larger than the lower rail and conforms better to the shape of the cylinder. The oil ring has a recess in its inner periphery to hold a compression member that forces the oil ring against the cylinder. The recess is extended beyond the compression member to provide a greater contact area between the oil ring and the groove.
