A high pressure coupling is provided which comprises an adjustment nut with nipples extending therefrom in axial extension of one another. The nipples are provided with exterior threads and with conically shaped ends which are respectively engaged by ferrules. Each of these ferrules is engaged by a coupling member having an interior thread which is in engagement with the threads provided on the associated nipple. Adjustment of the threads operates to pull the ferrules against the associated nipples. On each nipple is mounted a frusto-conical ramp adjacent which is provided an annular groove. Each coupling member is provided with a cylindrical arrangement of spaced fingers or a thin wall cylinder having protruding tips directed radially inwards. These fingers or the cylinder with their respective tips ride up the ramps until the tips extend beyond the ramps and are loosely accommodated in their respectively associated annular grooves. The accommodation of the tips in the annular grooves serves to lock the associated ferrules to the associated nipples to prevent accidental detachment thereof. The fingers pressing against the ramps serve to vector forces to remove play from between the inter-engaged threads.
A coupling comprising first and second axially displaceable parts, said first part including an exterior thread encircling the same, coupling means encircling said parts and including an interior thread to engage said exterior thread, said coupling means forcing said parts together responsive to adjustment of the engagement between the threads, said first part including a ramp, said coupling means including cantilever means adapted for riding up the ramp;
A coupling as claimed in 12 wherein the fingers have a thickness in the order of magnitude of about 0.10 inches.
A coupling as claimed in 22 wherein said ramp has an axial extent of an order of magnitude of about 0.135 inches.
A coupling comprising first and second axially displaceable parts, said first part including an exterior thread encircling the same, coupling means encircling said parts and including an interior thread to engage said exterior thread, said coupling means forcing said parts together responsive to adjustment of the engagement between the threads, said first part including a ramp, said coupling means including first cantilever means adapted for riding up the ramp;
