Abstract

A fluid coupling for establishing a sealed connection between a first conduit and a second conduit. The second conduit has a seal seat and a compression member. The compression member is movable relative to the seal seat. A seal is positioned in the seal seat. An engagement mechanism moves the compression member toward the seal seat to compress the seal to form a sealed fluid connection. The engagement mechanism has an input arm hinged to the compression member at a hinge connection. The input arm has a compression lever fixed at an angle to the longitudinal extent of the input arm. The input arm is arranged to push against the compression member as the input arm rotates about the hinge connection to the compression member. The compression member in turn pushes against the second conduit to move the second conduit relative to the first conduit, until the input arm reaches a predetermined angle about the hinge where the compression lever engages the second conduit such that further rotation of the input arm moves the compression member relative to the second conduit to compress the seal.
