  • Volumetric valve with independent display and resetting
    Patent number: 4202467
    Abstract: The invention relates to a volumetric valve which supplies a displayed liquid volume. This valve has a turbine which is rotated by the liquid and which drives a disk via a gear train. The disk rotates a spiral spring and a ring provided with a slot. A sliding push rod controls the opening of the valve flap and carries a lug which penetrates the slot. A knob makes it possible to vary the angular clearance between the slot and the lug, which determines the displayed volume.
