Abstract

CONJUNTO DO PISTON COM APOIO DE SOLDA. São revelados conjuntos de pistões exemplificativos e métodos de fazer os mesmos. Um pistão exemplificativo pode incluir um corpo do pistão que define um eixo do pistão, o corpo do pistão tendo uma saia e que forma uma superfície inferior de uma galeria de refrigeração. O corpo pode incluir superfícies de ajuste casado radialmente dentro e fora do corpo. O pistão pode ainda incluir um anel de galeria de refrigeração cooperando com o corpo do pistão para formar a galeria de refrigeração. O corpo do pistão e o anel da galeria de refrigeração podem ser unidos em conjunto ao radialmente no interior e regiões de interface radialmente exteriores para formar um conjunto de pistão geralmente de uma só peça. Em algumas abordagens exemplificativas, superfícies de acoplamento do corpo e do anel podem ser posicionadas adjacentes uma superfície de suporte configurada para inibir ou impedir os respingos de solda formados em um processo de união do anel e do corpo da galeria de refrigeração.
