| 摘要 |
The meter has an intake valve (4) rotationally fixed on a vertical measurement shaft and formed with diametrically opposed elongated openings (4a, 4b) to set front and rear compartments (A-D) of parallel cylindrical measurement chambers (6a, 6b) in communication with an inlet opening and an outlet opening. An internal wall of one of the rear compartments (C, D) is equipped with crumpled form flanges that define a rear limit stop for associated pistons (9a, 9b). The flanges have a frontal surface for allowing realignment of the pistons. |
