Abstract

a presente invenção refere-se a um sistema de vedação que consiste de um corpo-macho (1) e um corpo-fêmea (2) que são deslizáveis entre si em uma direção axial e que entre os quais se inclui um interstício por meio do qual pode passar plástico em estado fundido que esteja contido em uma câmara (3) parcialmente definida por pelo menos um dos corpos mencionados acima, com um anel de vedação (4) sendo disposto em tal interstício para evitar o vazamento do plástico.
