ABSTRACT:
A dispenser for pasty substances and/or liquids has two coaxially arranged metering pistons 11,24 which supply charges of material from two coaxially arranged pump chambers 14,23 through ejection channels 19,26 into an ejection chamber 20. The material can emerge from ejection chamber 20 through an outlet 4. This outlet 4 is controlled by means of plug 21 biassed in closing direction. When the metering pistons 11,24 are on their suction strokes material passes from the supply tanks 17,27 which are likewise arranged coaxially one inside the other. Such a configuration yields a dispenser which consists in essence of two separate dispensers, one inside the other. The two streams of material combine directly ahead of the outlet 4.
