COMPTEUR DE LIQUIDE A PIVOTAGE AMELIORE

摘要

The invention concerns a water meter (10) comprising a metering chamber (14) in which a turbine (16) is rotated about an axis (ZZ') and pivots, at least for low flow rate of liquid, on a support (46a-d) in a straight line with said axis, characterised in that the pivoting movement occurs via a ball (46d) rotating freely between two concave surfaces (46c, 48a) which have a bending radius strictly greater than that of the ball.
