Claims

[Scope of Claim for Utility Model Registration] It responds to the expansion and contraction of a pair of diaphragms 9 that partition left and right chambers formed separately on the left and right sides of the lower case 1 into inner and outer measuring chambers 7a, 7b, 8a, and 5b, respectively. A pair of left and right wing axes 10a are arranged in a point-symmetrical relationship. 10b rotates the rotary valve 4 via a link mechanism, and four independent fan-shaped holes 23a, 23b, 23C are arranged in a circle in a portion facing the valve and provided below the same valve. In a dry gas meter in which gas is introduced into and discharged from each of the measuring chambers by a valve seat 2 having a diameter of 23d, regarding communication of four fan-shaped holes of the valve seat to the four measuring chambers, The right wing shaft 10
The first fan-shaped hole 23a located closest to the left ventricular shaft 10b is communicated with the inner metering chamber 7a of the right ventricle through a first gas branch flow path 51a, and the second sector-shaped hole 23a located closest to the left wing shaft 10b is connected to A third fan-shaped ampulla 23b is connected to the outer metering chamber 8a of the right ventricle by a second gas branching passage 51b, and a third sector-shaped hole is located between the first and second sector-shaped holes and on the left ventricular side. The hole 23C is connected to the outer metering chamber 8b of the left ventricle through a third gas flow path 51C, and a fourth sector-shaped hole 23C is located between the first and second sector-shaped holes and on the right ventricular side.
3d to the inner measuring chamber 7b of the left ventricle through a fourth gas branch flow path 51d, and the left and right outer measuring chambers 8a, Qb
the second and third gas flow paths 5.1b, 51C leading to
The end openings 52b and 52C are connected to the left and right wing shafts 10a. The left and right inner measuring chambers 7a,
The first and fourth gas branch flow paths 51a leading to 7b
, 51d, and end openings 52a and 52d are formed near the center of the lower case 1.
