Abstract (en)

[origin: WO0046506A1] The invention concerns an injection pump for a dye dispensing machine, comprising a pumping section with bellows (23) and valves (30) capable of being selectively actuated to connect alternately the inner pumping chamber (24) with an access conduit (26) and a conduit dispensing (27) a dye. An indicator collar capable of being actuated is connected to the bellows (23) so as to selectively bring about expansion or contraction and cause the pumping section (24) to pass from a minimum volume to a desired maximum volume, and inversely. The position of the cursor is read by a sensor and transmitted to a high-tech electronic circuit comprising means for displaying a value concerning the position of the indicator collar.
