Abstract: An apparatus for pulsed dispensing of liquid. The apparatus includes a syringe body structure communicating with an input passage for pressurized actuation air, and communicating with an exit passage for allowing discharge of the liquid. An air input passage flow air controller is operative to increase the flow rate of the input air in accordance with a relationship that depends at least partially on a reduction of liquid volume in the syringe body structure resulting from a previous pulsed dispensing operation.
