<P>PROBLEM TO BE SOLVED: To provide a liquid feeding device capable of always feeding liquid of constant flow rate by reducing instability of liquid feeding caused by accuracy of processing of a cam, accuracy of phase of cams, and accuracy of processing of a section reciprocating with following the cam. <P>SOLUTION: Positions of liquid contact end parts of plungers 5a, 5b are measured with using measurement apparatus 23a, 23b such as a linear gage at every predetermined angle from a slit 16 (home position) provided on a disk member 15 fixed on a rotary shaft 1. Position parameters of the liquid contact end parts of the plungers 5a, 5b at every subdivided rotary angle is input from an input part 22. CPU 21 executes rotary speed control of a motor 14 based on the position profiles. <P>COPYRIGHT: (C)2009,JPO&INPIT |
