定風量装乳A constricted part 2 is provided in the middle of the duct 1, and an air volume adjusting valve plate 4 is attached so as to move forward and backward toward the opening 3 of the constricted part, and a plurality of springs 5, 5'... The valve plate 4 is installed in a state where it is biased upward, and the valve plate 4 is moved forward and backward under various pressure conditions so as to obtain a fixed amount through a wind passage test in advance, and the air force acting on the valve plate 4 at a position where the pressure becomes a fixed amount is determined. A constant air volume milking device characterized in that the springs 5, 5', etc. are adjusted so that equal paneka is generated at that position.
