A rotary union for a hose reel enclosure includes an inlet member in fluid communication with a fluid source. The rotary union further includes an outlet member rotatably disposed in the inlet member. The outlet member includes a first terminal in fluid communication with the inlet member and a second terminal in fluid communication with a hose in the hose reel enclosure. The rotary union also includes an inlet locking collar assembly. This design allows for efficient fluid transfer between the fluid source and the hose reel enclosure, providing a reliable and secure connection.

Some fluid coupling devices described herein are configured as non-spill fluid couplings. In addition, some embodiments described in this document relate to fluid coupling devices and fluid coupling systems that are constructed in a compact configuration.

A water transferring device is provided and comprises a body having a water passage chamber, a first water inlet joint having a first water inlet passage and connected to the body, and a water outlet joint having an outer water passage and an inner water passage. The first water inlet joint and the water outlet joint enable the inner water passage to be in communication with the first water inlet passage. The water passage chamber is in communication with the outer water passage. At least one of the first water inlet joint or the water outlet joint comprises a connection structure connected to the body and enabling the at least one of the first water inlet joint or the water outlet joint to be at least rotated for a specific angle around an axis of the at least one of the first water inlet joint or the water outlet joint.

The invention concerns a connector for connecting respiratory ducts together such that they are placed in fluid communication. The connector comprises a first conduit having a female connector end and a second conduit having a male connector end adapted to be received within the female connector end of the first conduit such that the male and female connector ends form a common conduit having an inner surface formed at least in part by the male connector end. The male connector has a retaining formation which is adapted to abut a corresponding formation of the female connector so as to resist separation of the first and second conduits while permitting relative rotation there-between when connected. The inner surface of the male connector may comprise a gas washed surface in use. The engagement formation is preferably a recessed area of the female connector, which may be generally annular in shape. In one embodiment, the member(s) may comprise a valve seat. The invention also concerns a breathing circuit comprising the connector.

A swivel bayonet joint for transferring cryogenic fluids includes a plug bayonet joint and a socket bayonet joint. The plug bayonet joint has an insertion stem with an insertion jacket surrounding and co-axial with a plug inner line of a corresponding pipe section, and a first clamp member having at least one race. The socket bayonet joint has a vacuum jacket at a distal end thereof that sleeves over the insertion stem of the plug bayonet joint, and a second clamp member having at least one race. When the plug bayonet joint is mated with the socket bayonet joint, the race of the plug bayonet joint aligns with the race of the socket bayonet joint to define a clamp member that is filled with ball bearings, the ball bearings functioning to lock the plug bayonet joint to the socket bayonet joint so as to allow rotation therebetween.
