ABSTRACT:
An aerosol valve assembly(12) has a mounting cup(18) with an arcuate bottom portion(43) that distorts during pressurization to absorb some of the pressure shock to enable pressurization at higher levels and a valve stem(22) with grooves(25) that define passageways through a bore(21) within which the valve stem(22) is slideably mounted to eliminate leakage through the bore and to reduce back pressure to enable good flow rates at reduced pressures.
