| titleOfInvention | Pressure accumulator-type liquid spraying device |
| abstract | A pressure accumulator-type liquid spraying device comprises a piston that is arranged in a cylinder; a piston guide that is disposed in and through a passage that penetrates through the piston in a direction along the axis of the piston, opens and closes the passage by the contact with and separation from the piston, and forms a space region for the suction and pressurization of liquid in cooperation with the cylinder and the piston; a check valve that opens a suction port of the cylinder when the liquid is sucked; and a hollow stem that is fitted slidably on the outside of the piston, with a liquid-tight state being kept, and engaged with an end of the piston guide. A first elastic member presses the piston guide against the piston to keep the passage of the piston in a closed state. A second elastic member presses the piston against the piston guide to adjust the spraying pressure of the content. The piston is positioned by a stopper, arranged in the cylinder, before the liquid is sprayed so that the contact surface pressure between the piston and the piston guide is increased and the passage is kept in a closed state. There is formed an annular recessed portion along an outer edge of a piston end portion with which the stopper comes into contact. |
