Abstract
An improved undersea coupler in which a fluid passage is provided in each coupling half. The opening of each passage proximal to the fluid source is controlled by a poppet valve. A sliding sleeve covers the other port of each passage, distal to the fluid source. These distal ports coincide when the coupler is connected, at which position the sliding sleeves are retracted. Sealing between the distal ports and the environment is accomplished by two metal seals backed up by two secondary elastomeric seals. Because the seal arrangement is balanced, and because of the passage design, the system pressure does not cause a high separation force.
