Abstract
A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinderthrough a suction valveby moving a vertically movable memberup and down, and the intra cylinder liquid is jetted out of a nozzlethrough a discharge valvefrom a stem. A plurality of ribsare protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portionsare formed in inner parts of the upper surfaces of the ribs. A lower edge of a coil springfor biasing the vertically movable memberis secured to each of the engagement recessed portions, thereby permitting a flow of liquid on both sides of the lower edge of the spring internally externally.
