Definitions

  • articles of the first category the reservoir which contains the ink is isolated from the ambient air and does not contain air; a flexible piston moves in the reservoir as ink is consumed and seals.
  • the valve 13 is in elevation relative to the peripheral rim 13a in the form of a sort of cup, the convex top 13h of which faces the inside of the reservoir 3 has two slots 16 perpendicular to each other. Due to the shape memory material used for this valve 13 and due to the curvature of the top 13h of said valve, the two slots 16 remain closed, in the normal position, and seal the tank 3 tightly. , when the reservoir 3 is pressurized by actuation of the membrane 12, this overpressure pushes the four tabs 17 delimited by the two perpendicular slots 16, which causes the valve 13 to open as soon as the ratio (A) of the pressure Pi inside the tank 3 on the pressure P 2 to the inside the volume of the anterior chamber 6 opposite the valve 13 is greater than a first value Ai.
