ABSTRACT:
The dispensing appliance for at least two components comprises a metering pump assembly with a housing comprising a metering cylinder for each component, each metering cylinder having an inlet and an outlet and a displacement plunger. The metering cylinders have eccentric outlet noses which end in a double outlet with a common outlet nozzle having their centers on a straight line which connects the centers located of the two metering cylinders and between the centers of the metering cylinders. In a preferred embodiment the cross sectional area of any pair of cylinder/displacement plunger combination between ratios of 1:1 and 20:1 is substantially equal. Such an assembly is modular, lightweight, highly compact, cost effective and can be easily disassembled for cleaning and maintenance.
