Abstract

PURPOSE: To provide minimal discharge fluid pump of ligh weight and low cost by constituting a pump which comprises piston and cylinder, and which is functional to press fluid into one push-away chamber by way of another push-away chamber formed underside of upper diaphragm.
CONSTITUTION: Remainder of ink from discharge pipe 6d is retrieved by pumping action of puch-away chamber 7 which is formed on one side of upper diaphragm 4. A pump for forcing fluid to flow into other push-away chamber 6 formed by piston 3 and cylinder 2b is constituted by still another push-away chamber 8 formed by cylinder body 2 and piston 3 on the other side of upper diaphragm 4. Accordingly, retrieving pump including chamber 7 and press-in pump including chamber 8 are together constructed with light weight and low cost. In addition, since every expansion and compression strokes as press-in action are corried out in opposite phase mode with each other, the press-in action is efficiently repeated.
