A charge valve assembly for an air conditioning system includes a valve housing having a first end, a second end, and an inner surface defining a cavity. A valve core assembly is received in the cavity of the valve housing through the second end of the valve housing. The valve core assembly has a first end, a second end, a flow channel extending from the first end of the valve core assembly to the second end of the valve core assembly, an inner sealing surface, and a pin slideably received in the flow channel between an open position and a closed position. The pin has a primary seal selectively engaging the inner sealing surface of the valve core assembly and closing the flow channel at the second end of the valve core assembly when in the closed position. The pin biases towards the first end of the valve housing.

A connector including a plug and a socket. The socket includes: a socket body having an insertion hole formed therein; a columnar rotary valve inserted into the insertion hole; and a switching mechanism for switching an open state and a closed state. The rotary valve includes a pair of convex portions respectively in contact with both ends of the insertion hole to seal an outflow of a liquid; and a concave portion provided between the pair of convex portions and forming a cleaning space) in which a cleaning fluid is circulated between the concave portion and an inner peripheral surface of the insertion hole. The socket body includes a cleaning fluid inflow passage for guiding the cleaning fluid to the cleaning space and a cleaning fluid outflow passage through which the cleaning fluid flows out of the cleaning space.

A quick connector includes a valve body and a rotatable ring fitting over the valve body. The rotatable ring is rotatable with respect to the valve body. When a sealing member of the rotatable ring is rotated to a full open position, an exit end and an entrance end of the valve body are both encompassed by an opening of the sealing member and communicating with each other. When the sealing member is rotated from the full open position to a full close position, one of the exit end and the entrance end is moved out of the opening and blocked by the sealing member, so that the entrance end and the exit end do not communicate with each other.

A valve injector (10) comprising: a body (12) defining a fluid conduit (14), the fluid conduit (14) accommodating first, second and third checks (16, 18, 20), the first check (16) being disposed within the fluid conduit (14) towards a first end (10a) of the injector (10), the second check (18) being disposed towards a second end (10b) of the injector (10), distally from the first end (10a), and the third check (20) being located between said first and second check (16, 18).

A fluid connector comprising a body having a through-bore, a plurality of radially inwardly facing surfaces comprising a first cylindrical surface having a first diameter, a frusto-conical surface adjacent the first cylindrical surface, and a second cylindrical surface adjacent the frusto-conical surface, the second cylindrical surface having a second diameter, wherein the frusto-conical surface is arranged between the first and second cylindrical surfaces, and a plurality of outwardly facing surfaces comprising a first cylindrical surface having a first diameter, and a second cylindrical surface adjacent the first cylindrical surface, the second cylindrical surface having a second diameter, and a deformable tab integrally connected to the body and extending axially from the body.

An assembly, connector and process for a quick connector is disclosed that includes a receptacle having first and second interior passages including a chamber in fluid communication between the first and second passages. A flow control insert is installed in the chamber to regulate fluid flow between the first and the second passage.

A quick connector assembly and a quick connector device are disclosed. The quick connector assembly includes a first base, a first fluid interface assembly and a valve assembly. The valve assembly regulates whether a fluid flows through the quick connector assembly or not, and thereby sealing the flow of the fluid at both sides of the quick connector assembly. The quick connector assembly and the quick connector device in an embodiment of the present disclosure can regulate the flow of the fluid effectively and provide better barriers to keep concurrent flows separated and isolated. Especially, the quick connector device can be used in slurry delivery system which has fluid being abrasive fluid or solid contained liquid.
