The fluid adapter comprises an adapter body defining an adapter chamber; a pressurized gas inlet port in fluid communication with the adapter chamber and arranged to be fluidically coupled to a source of pressurized breathable gas and an ambient air inlet port arranged to provide fluid communication between the adapter chamber and ambient air outside of the fluid adapter. The adapter also comprises an adapter outlet port in fluid communication with the adapter chamber and arranged to be fluidically coupled to a delivery device gas inlet port of the breathable gas delivery device; and an adapter connector arranged to connect the fluid adapter to the breathable gas delivery device such that the adapter outlet port is fluidically coupled to the delivery device gas inlet port.

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.

The invention relates to a device (1) comprising a first connector (100) and a second connector (200). The first connector (100) and the second connector (200) comprise a stationary body (102, 202) defining a fluid circulation conduit (104, 204) opening up into a connection opening (106, 206), and a valve (108, 208) that is movable in relation to the stationary body (102, 202), between a closing position in which the valve (108, 208) closes the connection opening (106, 206), and a release position in which the valve (108, 208) opens up a passage through the connection opening (106, 206). The device (1) also comprises first locking means designed to lock the movable valve (108) of the first connector (100) to the stationary body (202) of the second connector (200), and second locking means designed to lock the stationary body (102) of the first connector (100) to the movable valve (208) of the second connector (200).

In accordance with the present disclosure, leak of gas is suppressed when a coupler of a manifold gauge set including a gas hose is detached to a gas inlet/outlet valve of a thermal exchange equipment. To this end, the set includes a core-rod depressor extending from the coupler into the hose, and a depressor-adjustment unit disposed on the hose to adjust a position of the core-rod depressor.

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.

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 pure electric modular subsea test tree is provided, which includes a connect-disconnect device, wherein the first channel is formed in the connect-disconnect device; the connect-disconnect device is provided with a locking assembly and a connection drive mechanism for driving the locking assembly, and the first electrical connection plug is embedded in the connect-disconnect device, and the connection drive mechanism is electrically connected with the first electrical connection plug; a shear-seal assembly, wherein a second channel communicated with the first channel is formed in the shear-seal assembly; the shear-seal assembly includes at least one shear-seal device capable of plugging the second channel; a connection part is formed on the shear-seal assembly; a heating device is arranged at one end of the shear-seal device far from the connection part. The disclosure relates to a pure electric modular subsea test tree, which has fast response speed and high operation safety.

A quick water intake device comprises a tubular main body. The main body has a channel, and a first seal core, and an elastic piece. Under the action of the elastic piece, the first seal core can block the channel. A second seal core is also slidably arranged inside the main body. The second seal core is located between the first seal core and an outlet end of the main body, and when subjected to forces, the second seal core can move toward the first seal core and drives the first seal core to compress the elastic piece. A sealing structure arranged between an outer wall of the second seal core and an inner wall of the main body can form a seal between an outer wall of the second seal core and the main body to block the channel when the second seal core moves toward the outlet end.

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.
