Document Type and Number:
Japanese Patent JP4166871
Kind Code:
B2
Abstract:
A coupling system comprises a first coupling member having a tongue that projects axially a distance therefrom, and a second coupling member that is threadable attached to the first coupling member. The tongue is inserted within a groove disposed within a second coupling member body. The tongue is axially displaced within the groove by rotation of one of the first or second coupling member relative to the non-rotated coupling member to form a leak-tight seal therebetween. At least one of the first or second coupling member body includes a hollow passage that extends axially therethrough. An elastomeric member is disposed within the groove and is interposed between a base portion of the groove and an end portion of the tongue. The elastomeric member is sufficiently compressible to enable further axial displacement of the tonge within the groove after the leak-tight seal is achieved, thereby providing rotatable adjustment of the first and second coupling members vis-a-vis one another while maintaining such leak-tight seal. The elastomeric member enables the first or second coupling member to be rotatably adjusted from 1 to 360 degrees or more vis-avis the other, after contact between the tongue and elastomeric member, to achieve a desired orientation between the fluid handling members coupling members.
