Abstract:
A hose coupling for hoses handling relatively high fluid pressures, which hose coupling embodies a cup-shaped body having primary and secondary internal grooves in a wall defining a chamber, and a tubular pressure element having a deformable externally grooved end portion at one end, an intermediate externally tapered portion, and a collapsible end portion. The deformable grooved end portion is adapted to squeeze material into the primary grooves. The collapsible end portion is adapted to squeeze material into the secondary grooves so as to enhance the securement and sealing of the hose relative to the hose coupling. Ball means movable axially within the hose coupling are adapted to cause axial movement of the tubular pressure element so as to initially collapse the collapsible end portion thereof and subsequently, to deform the deformable grooved end portion. The ball means is adapted to be actuated by a rod that is releaseable therefrom, or alternatively, the ball means may be provided on a tubular coupling member that is adapted to extend through an opening in the end wall of the coupling and be actuable externally of the body.
