Abstract
An aerosol valve for high rate filling including an upper chamber and a lower chamber formed inside a housing. A stem is attached to the upper chamber in a vertically movable manner and a switching valve is attached to the lower chamber in a vertically movable manner. A narrow flow port is arranged in the switching valve to provide flow communication between the upper chamber and the lower chamber. The switching valve is pressed and urged against a valve seat of the flow port to close the flow port except for the communication of the narrow flow port, and the switching valve is pressed by filling pressure to open the flow port during a filling procedure of the content via the stem to thereby enable the content to be filled rapidly.
