Abstract (en)
[origin: WO2008029051A2] The invention relates to a liquid delivery device comprising a pump (1) and an anti-siphon valve (4) external to the pump (1), having an inlet pipe (3) connected to the outlet line (2) of the pump (1) and an outlet pipe (7), between which pipes are a seat (lia) and a moving part (11), which two are able to interact and define, between the inlet pipe (3) and the outlet pipe (7), a leaktight liquid flow region, said moving part (11) being able to move from an open position allowing liquid to flow in said flow region, to a closed position in which the moving part (11) contacts the seat (lia) of the valve (4) and prevents flow through said flow region, said moving part (11) being subject to the pressure of a reference chamber (5) which is not in fluid communication with the outlet pipe. Applicable to the making of a pump for injecting a medicinal liquid.
