ABSTRACT:
A device for dispensing metered quantities of flowable multi-component masses includes a housing with separate chambers, each containing a flexible bag with one component of the multi-component mass. Material is pressed out of the bags by a liquid propellant supplied from a reservoir in the housing to the chambers by gear wheel pumps located in a conduit connecting the reservoir to the chambers. The pumps are connected to a common drive so that the mixture ratio of the components is exactly maintained for any desired amount to be dispensed.
