Abstract
A radially offset valve is mounted in a bypass passage that extends through two movable members that are jointly moved during coupling between two couplers. The valve is moved from a closed position in which the flow of a pressurized fluid through a flow channel of an outer tubular body is prevented from being discharged through a discharge passage, to an open position in which the fluid is permitted to flow to the discharge passage, thereby resisting fluid leakage to the environment during coupling.
