Abstract
A volumetric fluid meter has a cylindrical measuring chamber with a lateral wall, a bottom (1) and a lid (3), a lower cylinder (4) and an upper cylinder (5), having the same diameter, which is less than the diameter of the chamber. An inlet orifice and an outlet orifice (8) respectively admit fluid to and evacuate fluid from the chamber. A cylindrical piston (11) is disposed eccentrically and guided kinematically in the chamber and effects an oscillatory movement in the chamber as a result of the displacement of a volume of fluid. A fixed partition (9) between the inlet orifice and the outlet orifice, lies radially between the lateral wall and the lower and upper cylinders, and lies axially between the bottom and the lid. The meter further includes a vertical groove (17) extending at least partly along the lower and upper cylinders and is in communication with one of the inlet and outlet orifices, and is situated in the vicinity of said fixed partition.
