Volumetric measuring device has two pistons for distribution of fuel

摘要

The volumetric measuring device for distribution of liquid fuel having an inlet orifice connected to a storage tank and an outlet orifice (5) connected to a nozzle, two pistons (9a, 9b) of an essentially horizontal axis, respectively, the mobile will -, - comes in the measurement chambers parallel cylindrical (6a, 6b), subdivided into a front compartment (a, b) and a rear compartment (c, d), a shaft of the measurement essentially vertical (12) cooperating with the detection members, and an intake valve (4) provided with openings (4a, 4b) of the compartments (a, b, c, d) of the measurement chambers (6a, 6b) in communication with the inlet orifice and with the outlet orifice, characterized in that the internal wall of the aft compartments (c, d) of each of the measurement chambers (6a, 6b) is equipped with at least one shoulder (2a, 2b, 2c, 2d) defining an end-of-travel stop for the piston (9a, 9b) associated.
