Abstract: A shuttle valve for a safety valve arrangement is provided with a valve housing (2), which includes a fluid inlet (4) and two fluid outlets (6, 8). A movable shut-off body (12) is arranged in the valve housing (2) and can be moved between two closure positions, in which the movable shut-off body (12) closes one of the fluid outlets (6, 8). The shut-off body (12) is arranged in a pivotably about a pivot axis (D). The shuttle valve includes a linear drive (46) which is coupled to the shut-off body (12) in a manner such that the shut-off body (12) is pivotable between its two closure positions by moving the linear drive (46).

Abstract: A ball-and-socket coupling for connecting two bodies to one another. The coupling includes a U-shaped welded support frame having a base as well as first and second legs extending from the base. The two legs are spaced from one another and define an open side of the frame opposite the base. The first leg forms a ball-holding pin, while the second leg is adapted to be attached to one of the two bodies. The ball-holding pin traverses and carries a ball of the coupling. A support bracket adapted to be attached to the other of the two bodies carries a socket in which the ball nests. A lid closes off the open side of the frame, and a securing device releasably attaches the lid to the frame.
