<p>A liquid material ejector which is adaptable for a liquid material of any viscosity, which has a structure where any part of the ejector has neither unnecessary projection nor extension in the horizontal direction with respect to the advancing/retracting direction of a plunger, and which enables a plurality of ejectors to be arranged side by side in a closely adjacent relation. The liquid material ejector comprises a liquid material supply port through which the liquid material is supplied, a nozzle for ejecting the liquid material, a valve block having a metering bore to be filled with the ejected liquid material and a liquid material supply channel communicating with the liquid material supply port, a selector valve having a first channel for allowing communication between the metering bore and the liquid material supply channel and a second channel for allowing communication between the metering bore and the nozzle, a plunger advancing and retracting in the metering bore, a plunger driving section for driving the plunger, a valve driving section for driving the selector valve, and a transmission section for transmitting driving power from the valve driving section to the selector valve, wherein the plunger driving section, the valve driving section, and the valve block are arranged successively in the longitudinal direction.</p> |
