PURPOSE:To realize both ways of normal upright state and reversed state, by keeping the sufficient airtightness of the contact condition of the closing ball of the passing way with the receiving opening thereof when closing the flowing way in a fluid ejection valve. CONSTITUTION:An aerosol valve is composed of an outer cylinder 4 having a feeding path 11 and a fluid ejection valve contained in the outer cylinder 4. And the fluid ejection valve structure usually closing the fluid ejection path 13 is provided between these outer cylinder 4 and the fluid ejection valve. The fluid is supplied from the feeding path 11 of the outer cylinder 4 to the fluid ejection path 13 so as to shut the closing ball 7 contained in the space in the outer cylinder 4 against the central opening of the packing 8 formed by a resilient material inserted inside the outer cylinder 4, when used in the normally erected state. The closing ball 7 is separated from the central opening of the packing 8 on using it in reversely erected state to pass through the opening and feed the fluid to the fluid ejection path 13 in order to eject the fluid to the outside. Accordingly, compressed evaporated gas can be prevented from leaking out. |
