Abstract: A liquid dispensing device for an automatic chemical analyzer or for other chemical apparatus. A dispensing tank is located inside a filling bulb. The dispensing tank has an inlet opening and becomes narrower above the inlet opening to form a vent. The dispensing tank is filled with the dosed liquid by an overpressure from a reservoir which is placed beneath the dispensing tank. The dosed liquid is pushed out from the dispensing tank through a dispensing pipe by regulated overpressure. A regulation tank, a filling bulb, and an isolation pipe isolate the liquid dispensing device from the reservoir and enable the dosing of liquid from a flow channel; or from a large tank, or from a pipe under pressure. A new construction of an air distributor with one nozzle controls the air flow in the liquid dispensing device. The air distributor may control one or more dosing devices.
