Abstract

PURPOSE:To prevent the occurrence of liquid feed pulsation, by a method wherein discharge pressure of a plural number of syringe type pumps are composed, and simultaneously, when the composition pressure reduces, a pressure is increased through the increase in the number of revolutions of a stepping motor connected to a syringe type pump. CONSTITUTION:Reciprocating movements are applied to their respective syringe type pumps 2 by the use of a driving electrode circuit 5, a stepping motor 4, and an uniform disc cam 3. Liquid is divided into two lots at a suction part IN, and the divided liquids enter their respective syringe type pumps 2 through their respective suction ports to feed them to their respective syringe type pumps 2 through check valves 1. The syringe type pump 2 perform a reciprocating movement with a motor controlled by means of a microcomputer 6. A change in pressure produced at a suction process of the first pump is erased through the forcible increase in a pressure resulting from the simultaneous increase in the number of revolutions of a stepping motor while the second pump is in a discharge process.
