Provided is a dispensing device capable of removing bubbles reliably. In this dispensing device, deaerated water is fed by a water feed pump to the inside of a pipeline up to the vicinity of the leading end of a dispensing nozzle. A water feed valve disposed near a dispensing pump is closed to establish a deaerated water space opened on the leading end side of the dispensing nozzle. The dispensing pump is activated on the space, thereby causing the dispensing nozzle to perform suction and exhaust actions. The dispensing device comprises a vacuum means connected to the space through the water feed valve thereby maintaining a vacuum state. In case the deaerated water space is cleared of the bubbles, the cleared water space is brought, by opening a change-over valve, into communication with a pipeline having a vacuum means connected thereto, thereby bringing the space into the vacuum state. |
