Japanese Patent JP3261618

B2

A coupling for joining together opposing ends of a pressurized refrigerant flow line utilizes a quick connect feature and provides a metal-to-metal seal when connected. When disengaged, opposing ends of the fluid flow line are closed by valves, each of which includes a structure containing an axial passageway and an axially extending valve positioned therein. The valves are yieldingly urged to a closed position when disconnected. The first structure and valve are mounted in a housing having a quick connect feature for retaining the second structure and valve. When connected together, the first structure and valve is moved axially relative to the second structure and valve, while the second structure is maintained in an axially fixed position in the housing. The axially extending first valve engages the axially extending second valve moving it relative to its structure from a closed to an open position while at the same time moving relative to a cooperating sleeve from a closed to an open position. Movement of the first structure in an axial direction causes it to engage the second structure metal-to-metal sealing engagement. Cams actuated by a rotatable handle mounted on the housing effect movement of the first structure.
