Abstract:
An ejection device includes a nozzle that ejects an ejection fluid, an ejection-side pump, a driving-side pump, and a heating unit. The ejection-side pump includes a pressure transmitting member, and an ejection chamber and a driving chamber adjacent to each other across the pressure transmitting member. The ejection chamber is filled with the ejection fluid. The driving chamber is filled with a driving fluid. The driving-side pump is a pump that applies pressure to the driving fluid. The pressure transmitting member transmits the pressure applied to the driving fluid to the ejection fluid in the ejection chamber. The heating unit heats at least the ejection-side pump while the driving-side pump remains unheated.

Claim (Index 1):
An ejection device comprising:\n a nozzle that ejects an ejection fluid; an ejection-side pump including a pressure transmitting member, a first ejection chamber connected to the nozzle and filled with the ejection fluid, and a driving chamber adjacent to the first ejection chamber across the pressure transmitting member; a driving-side flow path leading to the driving chamber; and a driving-side pump including a second ejection chamber communicating with the driving chamber through the driving-side flow path, wherein the ejection-side pump is attachable and detachable, if the ejection-side pump is attached, the driving chamber, the driving-side flow path, and the second ejection chamber are filled with a driving fluid, by application of pressure from the driving-side pump to the driving fluid in the second ejection chamber, the pressure is transmitted through the driving fluid to the ejection-side pump, and the ejection-side pump transmits the pressure having been transmitted through the driving fluid further to the ejection fluid in the first ejection chamber through the pressure transmitting member, thereby ejecting the ejection fluid from the nozzle, and if the ejection-side pump is detached, the nozzle is connected to the second ejection chamber and the second ejection chamber is filled with the ejection fluid, and by application of pressure from the driving-side pump to the ejection fluid in the second ejection chamber, the ejection fluid is ejected from the nozzle.
