Abstract
A valve assembly having both a primary low/fine product dispensing flow rate and a secondary high/coarse product dispensing flow rate. The primary low/fine product dispensing flow rate is achieved upon initial vertical depression of the valve stem while the high/coarse product dispensing rate is achieved upon maximum vertical depression of the valve stem. An internal compressible member is located within the valve assembly to provide a detectable indication, to an operator of the valve assembly, that further depression of the valve stem will increase the product flow dispensing rate from the primary low/fine dispensing rate to the secondary high/coarse dispensing rate. The internal compressible member is either a compressible spherical ball, located captively within the biasing spring between a lower surface of the valve stem and a floor of the valve housing, or a compressible cylindrical sleeve which captively surrounds the biasing spring and is located between a lower surface of the valve stem and a floor of the valve housing.
