ABSTRACT:
A ball and socket coupling is provided. The ball and socket coupling includes a ball body having a passage extending therethrough and a ball portion, and a socket body having a conduit extending therethrough and a ball receiving portion configured to receive the ball portion of the ball body. The ball and socket coupling also includes retaining structure disposed in the passage of the ball body and the conduit of the socket body, where the retaining structure is configured to operatively couple the ball body and the socket body together for permitting relative motion therebetween. The ball and socket coupling further includes motion limiting structure associated with the retaining structure and configured to limit relative motion between the ball body and the socket body to rotation about a single axis that is perpendicular to the direction of fluid flow through the ball and socket coupling.
