Definitions

  • the reference field is the field of pumping devices intended to pump liquids inside conduits of a hydraulic circuit.
  • the means (15) for drawing and pumping are disposed inside a container (16) that contains the liquid to be pumped and is fixed to the hollow body (11); said means (15) for drawing and pumping comprise an injection stem (17) provided with an end (18) that slides inside a dosage chamber (19).
  • said flow control element (20) can be in a closing position, wherein the flow control element (20) closes the outlet (19b) of the dosage chamber (19), and in an opening position, wherein the flow control element (20) does not close the outlet (19b) of the dosage chamber (19), allowing a dose of liquid to come out of the dosage chamber (19).
  • the dosage chamber (19) and the connecting channel (22) are defined in a single body (24), shown in Fig. 1A .
  • the single body (24) also comprises the flow control element (20) and the elastic closure means (21) of the flow control element (20).
  • said flow control element (20) can be in a closing position, wherein the flow control element (20) closes the outlet (19b) of the dosage chamber (19), and in an opening position, wherein the flow control element (20) does not close the outlet (19b) of the dosage chamber (19), thus transferring a dose of liquid from the dosage chamber (19) to the connecting channel (22).
