Summary:PROBLEM TO BE SOLVED: To provide a pressure-reducing mechanism 16 in a thin solution line 15, to guide diluted ammonia water solution Sw to an absorber 8 from a solution storing part 3 to store the diluted ammonia water solution Sw generated by a generator 1, and control to stabilize a circulation loop for an ammonia water solution between the generator and the absorber and accurately operate as a low-cost facility equipment is used, is practicable on an ammonia absorption refrigerating machine having a thick solution feed pump 9 to circulate and feed a thick ammonia water solution Ss provided in a thick solution line 18 to interconnect the absorber 8 and the generator 1. SOLUTION: A float trap 20 connected to the height position of a given liquid level in the liquid-storing part 3 is situated in the diluted solution line 15 and a valve seat 23 of the float type trap 20 is made to function as an orifice. An orifice is situated in the line 15 between the float trap 20 and the absorber 8, to constitute the pressure-reducing mechanism 16.
