ABSTRACT:
A dispensing device for mixing and dispensing multi-component liquid mixtures is described. The dispensing device comprises valve assemblies including a tapered valve plug and a correspondingly tapered valve seat and, downstream from the valve assemblies, respective orifices which provide access to a mixing and dispensing nozzle. The cross-sectional area of the orifices is about 1.7.times.10.sup.-4 to 2.0.times.10.sup.-3 sq. in. and the ratio of the cross-sectional area of the valve opening at any level of operation to the cross-sectional area of its respective downstream orifice is less than about 3.0. The device generally is configured as a dispensing "gun" and provides a capability for controlled variation in the flow rate of the liquid components and mixing of the components at a consistent volume ratio.
