A connector assembly for connecting together fluid carrying lines comprises two hubs having the bores of the fluid carrying lines extending therethrough. Openings are provided in the hubs and a clamp is provided in the openings. The clamp is connected to one of the hubs and comprises a clamp body, an operating member and clamping members movable radially outwardly to clamp the juxtaposed hubs together, movement of the clamping members being caused by sliding of the operating member in the clamp body, the inclined external surfaces of the operating member co-operating with the similarly inclined inner ends of the clamping members. The interior of the operating member is hollow and defines a cylindrical internal cavity. A piston is provided in the cavity to form a piston and cylinder assembly for moving the operating member. A releasable lock prevents inadvertent release of the clamping members.
A connector assembly for connecting together fluid-carrying lines, comprising two hubs, each hub having an end face, at least one bore for fluid extending through each said hub and opening into the end face thereof, and an opening in each said end face for clamping means, said bores and openings being alignable when said hub end faces are juxtaposed, the clamping means comprising a clamp body associated with said opening in one of said hubs, a plurality of clamping members carried by said clamp body and movable relative to said clamp body between retracted, inoperative positions and extended, operative positions, an operating member movable in an axial direction relative to said clamp body, said operating member comprising a plurality of planar surface portions inclined relative to said axial direction of movement of said operating member, each said clamping member being associated with a respective planar surface portion and having an inner face arranged to slide over said respective surface portion upon relative movement of said operating member and said clamp body to move said clamping members from their inoperative to their operative positions, said clamping members being adapted in their operative positions to engage at least said other hub to clamp said hubs together when said openings and bores in said hubs are aligned and said end faces thereof are juxtaposed.
A connector assembly for connecting together fluid-carrying lines, comprising two hubs, each hub having an end face, at least one bore for fluid extending through each said hub and opening into the end face thereof, and an opening in each said end face for clamping means, said bores and openings being alignable when said hub end faces are juxtaposed, said clamping means comprising a clamp body at least partially received in the opening in one of said hubs, said clamp body being fixed relative to said one hub and carrying a plurality of clamping members, an operating member movable relative to said clamp body for moving said clamping members from retracted, inoperative positions to extended, operative positions, said clamping members being adapted in their operative positions to engage said hubs to clamp said hubs together when said openings and bores in said hubs are aligned and said end faces thereof are juxtaposed, and means for moving said operating member, wherein said operating member is provided internally with a cylindrical cavity divided into two chambers by a piston slidable in said cavity, and said piston is fixed relative to said clamp body, said operating member being movable relative to said clamp body by the supply of pressurized fluid to said chambers.
A connector assembly for connecting together fluid-carrying lines, comprising two hubs, each hub having an end face, at least one bore for fluid extending through each said hub and opening into the end face thereof, and an opening in said end face for clamping means, said bores and openings being alignable when said hub end faces are juxtaposed, the clamping means comprising a clamp body associated with said opening in one of said hubs, a plurality of clamping members carried by said clamp body and movable relative to said clamp body between retracted, inoperative positions and extended, operative positions, an operating member movable in an axial direction relative to said clamp body, said operating member comprising a plurality of surface portions extending generally in said axial direction of movement of said operating member and being of constant inclination relative thereto, each said clamping member being associated with a respective surface portion and having an inner face arranged to slide over said respective surface portion upon relative movement of said operating member and said clamp body to move said clamping members radially with respect to the direction of movement of said operating member from their inoperative to their operative positions, said clamping members being adapted in their operative positions to engage at least said other hub to clamp said hubs together when said openings and bores in said hubs are aligned and said end faces thereof are juxtaposed.
