CONNECTING SECTION COMBINING PIPE FILLED WITH GAS OR LIQUID AND VESSEL WITHOUT LEAKAGE

摘要

A fluid coupler for making a leakage-free connection between first and second fluid-containing members. One half of the coupler comprises a plate having a conical opening in one surface across which an elastic sealing membrane is stretched by a clamping ring, the elastic sealing membrane having a slit at its center which is kept closed by the stretching action of the clamping ring. The other half of the fluid coupler comprises a hemispherical member having an axial aperture and a valve which is positioned within the aperture. When the two coupling halves are brought together, the hemispherical member presses against the elastic sealing membrane thereby opening the slit and expelling any air present in the coupling region.
