Self Sealing Couplings
Self Sealing Couplings


A self-sealing coupling for a manifold is constructed as to permit slight misalignment of the manifold and accessory ports. The coupling comprises male and female cartridges which are mounted on the manifold and accessory members. Each cartridge comprises housing mountable in the port, a ball segment body rock ably carried by the housing, and a self-sealing coupling valve mounted in the body.

Self-sealing couplings have been mounted in the manifold and accessory ports which open automatically when the two members are brought together. However, these couplings are so constructed that the ports on the manifold and accessory members must be substantially perfectly aligned in order for the couplings to open properly. Thus, extremely close tolerances are required for the manufacture of the manifold and accessory ports, increasing the cost of fabrication. The self- sealing coupling is in the form of two cartridges which are mountable in the manifold and accessory port members. Each cartridge has a housing which carries a rock able ball segment body. A self- sealing valve is mounted in each body, the construction being such that the valves will open when the port members are brought together. The rock able ball segment bodies will permit proper engagement of the coupling halves even though there is some misalignment between the ports themselves. In a self-sealing coupling (fluid) for connecting two members having ports which may not be exactly aligned, first and second cartridges, each cartridge having a housing mounted in one of the members in alignment with the port thereof, bodies mounted in the housings and having ball segment portions which permit limited rocking movement of the bodies with respect to the housings, means retaining the bodies in the housings, valves mounted in the bodies and connected to the ports whereby the valves are normally held in closed position by fluid pressure, and inter engaging surfaces on the valves and bodies responsive to the mating of the cartridges to open the valves, thereby permitting fluid flow between the ports, the ball segments permitting the inter engaging surfaces to be properly aligned despite misalignment of the ports.

Assembly- a self-sealing coupling assembly comprising a reciprocally movable fluid feeding unit and a stationary fluid receiving unit operatively associated therewith, said feeding unit including a coupling holder, a male coupling member mounted therein and a spring-loaded valve operatively associated with said male coupling member to open and close a fluid passage, and said receiving unit being in the form of a drum comprising a stationary circumferential sleeve, side flanges radially movable relative thereto, a female coupling member secured to said flanges a spring-loaded valve operatively associated therewith and a resilient support means connected at one end to said female coupling member and at the other end to said stationary sleeve so that said female coupling member is supported resiliently in suspension and radially movable together with said side flanges in response to and to absorb misalignment thereof with said male coupling member.
