CA 2189763

A new fluid coupling assembly (50) includes a split male nut (60, 62) positioned over a coupling mem- ber or gland (14) of a fluid system. The split male nut members (60, 62) are preferably formed of a precipita- tion hardenable material. Various in- terlock arrangements facilitate assem- bly of the split male nut halves (60, 62). Moreover, providing indicia (170) on the male nut halves (60, 62) assists in forming the threads (70) and subse- quent assembly. A female nut assem- bly includes a pair of inserts that are secured together by a collar having a shoulder (64) defined by a counterbore (220). An external portion of the shoulder (64) overlaps the counterbore (220) formed therein to increase the strength of the female nut assembly.

Nouveau type de raccord pour fluides (50) comprenant un écrou mâle fendu (60, 62) situé sur un organe de raccordement ou presse-étoupe (14) dans un système de circulation de fluides. Les écrous mâles fendus (60, 62) se composent de préférence d'une matière durcissable obtenue par précipitation. Plusieurs agencements d'emboîtements facilitent l'assemblage des demi-écrous mâles fendus (60, 62). En outre, la création de repères (170) sur les demi-écrous mâles fendus (60, 62) facilite la formation des filets (70) et l'assemblage successif. Un raccord à écrou femelle comprend une paire de pièces rapportées qui sont maintenues ensemble par un collier présentant un épaulement (64) délimité par un logement cylindrique (220). Une partie externe de l'épaulement (64) chevauche le logement cylindrique (220) formé à son intérieur, de façon à augmenter la résistance du raccord à écrou femelle.
