Abstract
A coupling member for a blind mate fluid coupling includes a housing and a valve body that is self-centering and alignable relative to the housing. The valve body may include at least two radial shoulder portions that are configured to engage at least two corresponding radial abutments of the housing to improve self-centering when in a decoupled state. An engagement member, such as a socket, may be provided in the housing to engage a radial shoulder of the valve body with a concave interface to enhance the misalignment compensating and/or self-centering functionality. The engagement member may be free to float radially relative to the housing to further enhance such effects. A compensator that urges an engagement member against a shoulder of the valve body may be provided to compensate for misalignment and/or provide self-centering in both a decoupled and mated state.
