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.
Claims6
Device for dispensing metered quantities of flowable multi-component masses, comprising means forming at least two separate closed chambers, a flexible bag containing a component of a multi-component mass positioned within each said chamber, a reservoir containing a fluid propellant, conduit means interconnecting said reservoir and said separate chambers, a device in communication with said conduit means for conveying the fluid propelant from the reservoir into the separate chambers for dispensing metered amounts of each of the components to an outlet where the components are mixed, said device for conveying the fluid propellant comprises pumps with a volumetric output, said conduit means comprises a separate conduit line for each of said chambers, and one said pump in each of said conduit lines for withdrawing fluid propellant from said reservoir and delivering the fluid propellant into said chambers, and said pumps in each of said conduit lines are coupled to one another.
