Abstract

PURPOSE: To obtain a stabilized discharge by a method wherein a rotation frequency of discharged liquid fluctuated when a direction in which the plunger moves is modified returns to a set flow-rate.
CONSTITUTION: a buffering liquid sucked from a buffering liquid tank 17 to the plunger pump 18 is detected by a pressure detector 19 for the pressure at discharging. An output signal of the pressure detector 19 is fed as an input to a micro-computer and processed, and a number of the rotations of the pulse motor 51 is controlled through a controlling device 21 to make the amount of the discharged liquid of the plunger pump 18 constant. At a time point when the plungers 5a, 5b on the discharging side are changed over, the discharge decreases and at the same time a revolving speed of a cam 10 is increased and pulses of the discharge are arrested to obtain the stabilized amount of the discharged liquid.
