A ball joint having first and second coupling parts connected thereto in an articulated manner, which coupling parts have interconnected liquid ducts. second coupling part is held pivotably by a spherical front end region between a shape-adapted joint socket on the first coupling part and a joint head on a holding element provided in the inner cavity of the second coupling part. The holding element interconnects the liquid ducts of the first and second coupling parts, and the second coupling part has, on its inner wall delimiting the inner cavity, an annular groove in which a ring seal is provided. A first annular shoulder is provided on the inner wall of the second coupling part, an annular or sleeve-shaped insert part can be inserted into the inner cavity of the second coupling part, and the insert part is spaced apart from the first annular shoulder such a that the spacing between the first annular shoulder and the front edge of the insert part that faces the first annular shoulder forms the annular groove.

A fluid system and a blind-mate fluid fitting can be operable to allow for mating fluid system components even in the presence of angular, radial, and/or axial port misalignment. The blind-mate fluid fitting includes a shoulder and fitting portion extending from one side of the shoulder. The fitting portion defines a central fitting axis and is operable to inserted into a fluid port of a component. The fluid port defines a central port axis. The fitting portion includes a sealing portion that is operable to seal against the fluid port when the central fitting axis is positioned at a zero angle and at least one of a plurality of different non-zero angles relative to the central port axis.

A fluid coupling includes an inlet housing member, an outlet housing member rotatably connected with the inlet housing member to define a chamber, a regulator assembly disposed in the chamber and connected to the outlet housing member, a main poppet configured to control fluid flow between the inlet housing member and the outlet housing member, and/or a pilot poppet configured to selectively permit fluid flow through the main poppet. The outlet housing member may be configured to mate with and at least partially receive a nozzle. The regulator assembly may include a regulator housing and a regulator.

A quick connect fluid connector is directly connected to a fluid port of a fluid manifold using a quick connect fluid connector swivel that is configured to permit rotational and/or longitudinal movement of the quick connect fluid connector relative to the fluid port. The relative axial and/or rotational movements provided by the swivel eliminates the need for a fluid hose to be used in the fluid path between the quick connect fluid connector and the fluid port.

A fluid connector that connects a first fluid system with a fluid port of a second fluid system for transferring fluids, including gaseous or liquid fluids, between the first and second fluid systems. The fluid connector can be used with differently configured, non-matching threaded fluid ports and allow for misalignment/tipping of the fluid connector to maintain a seal with the fluid port.

A hinged connection device includes first and second tubular components around a main axis which respectively include a first male hinge member provided with an end head shaped as a spherical segment and a second female hinge member provided with a complementary seat receiving movably inside the end head of the first member. The first member is configured to be housed at least partially inside the first component and to be assembled to the second component throughout the second member. The second member is configured to be mounted around the second component and assembled to the first component over the first member such that the two tubular components are assembled together by the reciprocal intersection of the two hinge members.
