Abstract

"VáLVULA DE BLOCO COM LINHAS INTEGRAIS DE REFRIGERANTE". Uma montagem de refrigerante inclui uma válvula de expansão termostática do tipo bloco (7) e um ou mais tubos de refrigerante (8). A válvula de bloco (7) tem um corpo (17) com um orifício (15, 23, 48, 52) definido por um furo axial (85) e um primeiro rebaixador (86) coaxial com o furo (85). O orifício (15, 23, 48, 52) estende-se para dentro de uma superfície, e o tubo de refrigerante (8) é recebido no orifício (15, 23, 48, 52). O tubo de refrigerante (8) inclui um friso anular (82) que é estreitamente recebido no interior de um rebaixador (86) . A superfície do corpo (17) circunda o rebaixador (86) e é mecanicamente deformada, de preferência por repuxo, em torno da circunferência inteira do tubo de refrigerante (8) de tal modo que o material do corpo (17) é forçado radialmente para dentro em direção ao tubo (8). O material do corpo (8) encerra pelo menos parcialmente o friso de tubo de refrigerante (82) no interior do rebaixador (86) para fixar o tubo de refrigerante (8) ao corpo de válvula (17) . Uma borda aguda (94) entre o rebaixador (86) e furo (85) é forçada contra a junção entre o friso (82) e o tubo de refrigerante (8) para fornecer uma vedação hermética a fluido.
