PROBLEM TO BE SOLVED: To provide a one-way valve capable of being set in a saved space at a low cost with a small number of man-hour. SOLUTION: In this one-way valve, a body 1 is compactly formed by integrating a flange part having a mounting hole 12 for inserting a bolt for fixing to the mounting part of a refrigerant discharge port to a male joint 2 to be fitted to the mounting part. A valve seat 5 is formed within a refrigerant passage linearly formed in the body 1, a valve element is protrusibly and retreatably arranged opposite to the valve seat 5 in an axial position opposite of the refrigerant passage, and a spring 11 is provided to energize the valve element in the direction of seating it in the valve seat 5. Since such a one-way valve is clamped and mounted between the mounting part and the flange mounted on the tip of a pipe, a pipe between the one-way valve and a pipe connecting pedestal is dispensed with, and the setting space can be minimized at a low cost. Since the mounting of the one-way valve is performed simultaneously with pipe connection, the man-hour of mounting can be minimized.
