Abstract
A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinder through a suction valve by moving a vertically movable member up and down, and the intra cylinder liquid is jetted out of a nozzle through a discharge valve from a stem . A plurality of ribs are protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portions are formed in inner parts of the upper surfaces of the ribs. A lower edge of a coil spring for biasing the vertically movable member is 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.
