Abstract

GAXETA PARA UMA VáLVULA EM UM MOTOR DE COMBUSTãO INTERNA. Gaxeta para uma válvula em um motor de combustão interna é proporcionada com uma primeira porção elasticamente deformável adaptada para cooperar com uma vareta da válvula. Uma segunda porção elasticamente deformável adaptada para cooperar com uma superfície externa de um elemento de guia da válvula e uma terceira porção elasticamente deformável é interposta entre a primeira e a segunda porção elasticamente deformável e uma borda de selo de aperto de gás de mancal é adaptada para cooperar com a vareta da válvula. A borda mostra uma configuração frusto-cónica com uma cessão decrescente na direção oposta às forças de pressão direcionadas para a primeira porção elasticamente deformável e é conectada à terceira porção elasticamente deformável em sai parte de seção maior. A borda é ainda conectada no lado exposto às forças de pressão à terceira porção elasticamente deformável por uma superfície que porta uma ou mais ondas.
