Abstract: A tilting-type aerosol valve comprising a cup-shaped valve housing which is covered by a resilient annular discharge-valve seat. A hollow valve stem extends through the valve seat and carries an annular valve shoulder inside the housing. The shoulder is engageable with the seat to close off the discharge. Within the housing there is a supporting boss on the valve stem, located below the valve shoulder and engageable with an opposite wall of the valve housing to normally maintain the valve shoulder and seat engaged whereby the valve is closed. The stem can be tilted, however, because the shoulder can compress a localized area of the seat. This separates another portion of the shoulder from the seat, whereby liquid can flow from the housing, but through the hollow valve stem.
