The intermediate member is located in the case and includes an opening formed at a front area thereof for mounting the liquid connector main body therein, a locating bore located below the opening, and a plurality of elastic elements mounted on outer sides and a rear side of thereof. The intermediate member is supported by the elastic elements to suspend in the case and the elastic elements absorb assembly tolerance of the adaptable liquid connector structure, such that the liquid connector main body mounted therein is allowed for a positional floating adjustment in and relative to the case upward, downward, leftward and rightward to be smoothly, correctly and securely connected to an adaptor connector.

An embodiment of a fire-suppression water-intake valve includes a receptacle and a valve assembly. The receptacle is configured to receive a sprinkler head. And the valve assembly is configured to close in response to removing a sprinkler head from the receptacle, and is configured to open in response to installing a sprinkler head in the receptacle. Such a fire-suppression water-intake valve can allow quick and easy removal and installation of a fire-suppression sprinkler head without shutting a water supply to the valve.

A docking system useful to connect and place in communication a first operating unit (3) including one or more fluid accumulators and at least one second mobile service unit (7) carrying fluid in a reservoir for refilling the accumulators. The operating unit and the at least one second mobile service unit each include hydraulic connectors carried by a floating support connected to a float supporting device to facilitate alignment and connection of the hydraulic connectors. In one example, the docking system includes a stationary intermediate structure (5) to indirectly connect and communicate the hydraulic connectors of the operating unit and the second mobile service unit. In one example, the at least one second mobile service unit is an automated guided vehicle or an autonomous mobile robot.

Male or female fluid coupling element and fluid coupling including such an element This coupling element has a body and a nozzle. The body delimits a housing for partially receiving the nozzle. The nozzle has a tubular part and a flange received in the housing. Two sealing barriers formed by at least one sealing joint are interposed between a rear surface of the flange and a front face of the body, between a front surface of the flange and a rear face of the body, respectively. A plug caps an inner conduit. Portions of the inner conduit communicate through at least one passage opening into an inner volume of the nozzle, forward of the plug, and on an outer peripheral surface of the flange. An inner chamber is separated from the inner conduit by the body, the flange, the plug and the first sealing barrier.

A flexible pipe fitting for joining a first length of pipe to a second length of pipe at an arbitrary angle is provided. The apparatus includes a primary fitting having a substantially circular opening at a first end thereof for receiving an end of a first length of pipe, and an enlarged opening at a second end thereof for receiving a first flexible coupling member. The first flexible coupling member includes an outer wall having an outer surface engaging an inner surface of the enlarged opening, and an inner wall having a lower end connected to a lower end of the outer wall. The inner wall further includes a substantially circular opening therein for receiving a second, rigid member. The inner surface of the second, rigid member is configured to receive an end of the second length of pipe. The enlarged opening in the primary fitting is preferably fish-mouth shaped, or alternatively, cone shaped. Adhesive, such as PVC cement may be used to bond the various fittings, and lengths of pipe together to form a sealed joint.
