PURPOSE: A cylinder for a reciprocation pump suitable for requesting fluid supply is provided to quickly supply the supplied fluid and raise the supply of the fluid by increasing the volume of the cylinder room. CONSTITUTION: A cylinder for a reciprocation pump includes a cylinder chamber(112) and a flap valve. The cylinder chamber installs each piston(114). The flap valve selectively intercepts the fluid by electrically protruding the flap valve by fluid pressure created by the movement of pistons and includes an opening/closing unit which selectively intercepts the fluid.
