Zusammenfassung: | A pump fixed to the opening of a liquid container in which both of a suction port and a liquid discharge passage are firmly opened and closed in response to the movement of a piston which has a considerable axial length so as not to deform itself upon its downward movement in a cylinder for exerting pressure on the liquid therein. Spraying operation is effective; leakage of liquid from the container is prevented even when the container is turned upside down; and the pump may be comprised of a lesser number of parts, which are fabricated at less costs. |
