Abstract:
An aerosol valve and flow regulator assembly for use with a can containing product to be dispensed and compressed gas propellant, comprising in combination an aerosol valve and a valve housing containing the aerosol valve and flow regulator; said flow regulator being positioned upstream of the aerosol valve and including a conical valve seat of hard material extending inwardly of the valve housing and having two diametrically opposed triangular grooves extending along the length of the conical valve seat in the flow direction; said flow regulator further including a relatively soft elastic regulating member having a surface for contacting and sealing the conical valve seat under gas pressure from the can and for pressing into said two triangular grooves under higher gas pressures to regulate the product flow area of the two triangular grooves over a substantial range of gas pressures, to provide a substantially constant product flow rate over the substantial range of gas pressures.
