Abstract

PURPOSE: To prevent pulsation by the use of a container possible to expand and contract and a piston.
CONSTITUTION: A container 2 free to expand and having an intake 21 and an outlet 22, a piston 31 receiving the pressure of fluid encapsulated in a tight container 2, and elastisity elements 33, 34, 35 which produce a resistant force against the pressure of fluid applied to this piston 31, are encapsulated in a sealed container 11. According to the above-mentioned construction, if the inner pressure of the container 2 is raised and the container expands under the phase that the pump 43 is discharging the carrier liquid, the piston 31 is lifted up through the action of the lubrication oil 21 which conducts pressure. consequently, the springs 33 W 35 come into work and the check valves 44, 45 are closed while the pump 43 is sucked against the expansion of the container 2, that commences supply of the carrier liquid being reserved in the container 2 which is made free to expand and contract. Thus the change of the rate of flow of the carrier liquid fed to the cloumn is suppressed.
