Abstract: A self-sealing hydraulic device has a connecting assembly and a hydraulic assembly. The connecting assembly has an adaptor having a shell, a male fitting, and a barb fitting. The male fitting is mounted in the shell, is axially moveable relative to the shell, and has an axial hole and a radial hole orthogonally communicating with the axial hole. The radial hole is sealed by the shell. The barb fitting is connected to and communicates with both the shell and a hose. The hydraulic assembly is assembleable to the connecting assembly and has a housing, an elastic element, and a valve unit. The housing has a hydraulic chamber and an assembling hole communicating with the hydraulic chamber via a through hole. The elastic element is disposed in the housing. The valve unit is disposed inside the hydraulic chamber and driven by the elastic element to seal the through hole.

Abstract: An embodiment of a fluid valve includes a substantially flat face plate, a receptacle, a cavity, and a valve assembly. The receptacle is disposed in the face plate and has at least one protrusion each configured to engage a respective at least one groove of a valve-opening-and-fluid-dispensing device. The cavity has a front end in fluid communication with the receptacle, and has a rear end. And the valve assembly is disposed in the cavity, includes a first sealing ring, is configured to form a seal by urging the sealing ring against the rear end of the cavity in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle, and is configured to allow fluid to flow into the rear end of the cavity in response to the valve-opening-and-fluid-dispensing device being disposed in the receptacle.

Abstract: A valve comprises a shell, a flexible valve member sealingly mounted within the shell, and a valve body mounted atop the flexible valve member within the shell. The flexible member is moveable between closed and open positions to allow the flow of fluid therethrough. The valve is engageable with a filling device having flow ports and a surrounding closure. The closure and/or the shaft is movable between (i) a first position wherein the closure closes the port(s), and (ii) a second position opening the port(s). Alternatively, the valve may comprise a portion of a female connector and the filling device may comprise a portion of a male connector to form an aseptic fluid connector for the aseptic transfer of fluid therethrough.

Abstract: A self-sealing end fitting includes a valve, an adaptor, and a connector. The valve may define a longitudinal axis and may include a first end portion, a second end portion, a flange disposed therebetween, and a central bore. The adaptor may have a first end portion surrounding at least the second end portion of the valve, and the connector may surround at least the first end portion of the valve. A portion of the connector, a portion of the flange, and a portion of the first end portion of the adaptor may define a pocket. The valve may be configured to move axially relative to the adaptor. In embodiments, a sealing surface of the flange may contact a corresponding sealing surface of the first end portion of the adaptor to form a first seal within the pocket, and the first seal may comprise a metal-to-metal seal.

Abstract: A normally closed port valve seals a hydraulic hose connection port of a hydraulic bicycle component. Connection of an end of a hydraulic hose assembly to the port opens the valve, placing the assembly's hydraulic fluid chamber in fluid communication with the interior of the hose assembly. A hydraulic cylinder of the assembly is in fluid communication with the chamber. A spring may be used to bias the valve to a closed condition and simultaneously to bias a brake actuating piston to a non-actuated position.

Abstract: A probe seal for a female hydraulic coupling member has both internal and external pressure-energized seals. The outer wall or opposing ends of the seal have one or more pressure-energized seals for sealing between the body of the probe seal and the body of a coupling member in which the probe seal is installed. Annular, L-shaped, T-shaped or angled grooves in the inner wall of the seal form cavities and sealing projections that can be urged in an inward, radial direction by fluid pressure within an associated cavity to increase the sealing effectiveness between the body of the seal and the probe of a male hydraulic coupling member inserted in the receiving chamber of the female coupling member.

Abstract: A device for charging a primary fluid system, such as an air-conditioning or cooling system, closed and at a first pressure (P1), with a secondary fluid, comprises a dispensing cylinder of the secondary fluid, said cylinder containing the secondary fluid and a propellant fluid having a second pressure (P2) greater than said first pressure. Said cylinder further comprising a filler valve operable to allow/block the exit at least of the secondary fluid from the cylinder. A connection hood is partially superposed over the dispensing cylinder, fitted with connections means suitable for fluidically connecting said filler valve directly to said primary fluid system or to a connection pipe to said system.

Abstract: A pressure sensor includes: a pressure sensor element; an adapter integrally attached to the pressure sensor element and defining therein a hole where a pressure of a fluid to be measured is introduced to the pressure sensor element; a fitting member having a housing recess housing the adapter and connectable to a connected member; and a pressing member pressing a valve of the connected member and defining a communicating path through which a flow path where the pressure of the fluid is introduced is in communication with the hole of the adapter. The fitting member is made of a synthetic resin. An O-ring is interposed between a circumferential surface of the adapter and the fitting member. The adapter is a synthetic resin member, and includes a contact portion brought into contact with the adapter and a pressing portion pressing the valve. The pressing member is welded to the fitting member.
