A hydraulic coupling bush which is actuated in order to close or open the coupling includes a coupling housing and a bush body which displaceable therein and which has a plug space for receiving a coupling plug, a supply space for fluidic connection to an external supply channel, a low pressure space for fluidic connection to a pressure medium sink, and an interior space connected fluidically to the supply space, a supply seat valve device being provided, via the actuation of which a supply flow path can be configured between the supply space and the plug space, and a relief seat valve device being provided, via the mechanical actuation of which the interior space can be relieved of pressure toward the low pressure space, and via the hydraulic actuation of which, which is dependent on the pressure in the interior space, the pressure in the interior space can be limited.

A female coupling device includes: a main body, and a clip member coupled to the main body, the clip member having a plurality of arms extending perpendicularly therefrom, with the plurality of arms forming at least one pair of arms, with the pair of arms including a first distance therebetween and a second distance therebetween, with the first distance being sized to engage a clip groove of a mating male coupling device, and with the second distance being sized to disengage the mating male coupling device. In a locked position, the pair of arms is positioned so that the first distance is adjacent to the mating male coupling device. In an unlocked position, the pair of arms is positioned so that the second distance is adjacent to the mating male coupling device.

A joint, a knob assembly, and an appliance having a joint and a knob assembly are provided. The joint may include a housing, a first shaft support, a second shaft support, and a coupling shaft. A slot having a predetermined width extending in a circumferential direction of the housing and a predetermined length extending in a longitudinal direction of the housing may be formed in the housing. The coupling shaft provided in the second support may include a rotary shaft rotatably inserted into the slot. A stopper may be formed to protrude from an outside of the rotary shaft, and a position of the stopper inside the slot may be changed according to rotation of the rotating shaft. The stopper may be provided in the slot so that the stopper interferes with an inner wall of the housing formed by the slot at a predetermined position.

A tube fitting and a tube fitting enabling a configuration that limits a through-flow rate of fluid that has passed through a flow aperture opened by a valve unit are obtained. An upstream-side choke hole in an upstream-side choke section limits the through-flow rate of the fluid. In a case in which the fluid flows at a flow rate exceeding the through-flow rate limited by the upstream-side choke hole, the valve unit opens the closed flows aperture in a flow path. A downstream-side choke hole in a downstream-side choke section disposed at a downstream side of the valve unit limits the through-flow rate of fluid that has passed through the flow aperture.

A connector for facilitating the connection of one piece of tubing to another so that fluid can flow from one piece to the other in a sterile manner. Characteristics of the connector include, but are not limited to, a flange at one of the connector, the flange comprising a recess for storage of at least part of a protective shield which Is removable after the flange is connected to the flange of a second connector.

A coupler for use in a closed transfer system is provided. The coupler includes a body with an axial slot, an outlet, and a probe that extends from a first end portion to a second end portion and at least partially received within the body, the probe configured to be movable relative to the body between a first position and a second position to selectively control the flow of fluid through the outlet. A handle is coupled to the probe and configured to interface with the axial slot, wherein the handle is configured to move axially along the axial slot to move the probe between the first position and the second position.

A female coupling for a fluid quick connector and configured to be removably connected to a male coupling of the connector. The female coupling includes a valve assembly with a valve alternating between closed and open positions. The flow of a fluid from the female coupling towards the male coupling occurs in the open position. The female coupling includes a hollow body defining an inner cavity with a longitudinal axis for the flow of the fluid. The female valve assembly is housed in the inner cavity. The hollow body includes an end portion configured to be housed in a housing seat of an interface manifold. With the end portion in the housing seat, the tubular inner cavity is placed in fluid connection with at least one inner channel of the interface manifold. A constraint prevents rotation/translation of the end portion of the hollow body with respect to the housing seat.

Refrigerant charging systems and methods of use are described herein. A refrigerant charging system may include a conduit, a valve releasably connectable to the outlet portion and coupled to a first end of the conduit; and a disconnect coupler fitting connected to a second end of the conduit. The disconnect coupler fitting may include a control structure positioned in a hollow body that, during use, allows refrigerant flow to the refrigerant circuit. The control structure may include one or more openings that allow controlled leakage of fluid from the refrigerant charging assembly when the refrigerant charging assembly is disconnected from at least the refrigerant service unit.

There is disclosed breathing apparatus equipment which may be in the form of a waist mountable manifold. The breathing apparatus equipment comprises a manifold having a manifold inlet port for a source of breathable gas and at least one manifold outlet port for delivering breathable gas to a user. The equipment further comprises a strap arranged to be worn by the user, and a holder coupled to the strap and having a socket. The socket is configured such that the manifold can be removably located within the socket in multiple orientations.

Embodiments of the invention provide a coupler for use in a closed transfer system configured to selectively engage a container seated in fluid communication with the coupler. The coupler has a body with a slot having an axial component, and an outlet. A probe extends from a first end portion to a second end portion and is at least partially received within the body, the probe is configured to be movable relative to the body between a first position and a second position to selectively control a flow of fluid through the outlet. A probe tip with a cylindrical bore is configured to engage the second end portion of the probe, and a handle is coupled to the probe and configured to interface with the slot. Axial movement of the handle along the slot moves the probe between the first position and the second position.
