摘要:
A liquid jetting pump of the present invention is constructed such that an intra container liquid is sucked into a cylinder 3 through a suction valve 9 by moving a vertically movable member 4 up and down, and the intra cylinder liquid is jetted out of a nozzle 29 through a discharge valve 31 from a stem 28. A plurality of ribs 10 are protruded in a peripheral direction from a lower edge part within the cylinder. Engagement recessed portions 11 are formed in inner parts of the upper surfaces of the ribs. A lower edge of a coil spring 38 for biasing the vertically movable member 4 is secured to each of the engagement recessed portions 11, thereby permitting a flow of liquid on both sides of the lower edge of the spring internally externally.
