[origin: WO2006125880A1] The invention concerns a pump (1) for dispensing liquid or semi-liquid product, designed to be used in particular in the pharmaceutical or cosmetic field. The pump (1) comprises a needle valve (2) and a dispensing head (4) manually movable on the pump housing (5) between an inactive position and a punctual product dispensing position. The head (4) includes a first cylinder (41) forming a metering chamber (7) of the pump, which communicates with a take-off tube (42) via a non-return valve (43), a piston (44) being slidably mounted in said first cylinder (41). The head also includes a second cylinder (5) wherein is slidably mounted said needle valve (2), means for elastic return (6) of the needle valve (2) in position for closing an orifice (45), and means (46) for allowing the liquid to pass between the metering chamber (7) and a second chamber (8) provided at the end of said dispensing head (4), said second cylinder (5) having a compartment (51) wherein are housed the elastic return means (6) and which is isolated from said second chamber (8) by sealing closure means (52).
