FLUID DISPENSER AS WELL AS METHOD FOR THE PROVISION OF A WORK FLUID BY MEANS OF A FLUID DISPENSER

摘要

PURPOSE: A fluid dispenser and a working fluid supply method using the same are provided to control the working pressure of working fluid and to variously control an injection rate. CONSTITUTION: A fluid dispenser comprises a transfer cylinder(3) and a pressure emitting unit(11). The transfer cylinder has a transfer piston(4). The transfer piston divides the transfer cylinder into control and transfer spaces(5,6). Working fluid(2) is supplied to the transfer space through an inlet(9). Control fluid(8) is supplied to the control space through a control inlet(7). The pressure emitting unit controls the working fluid of the working fluid.
