Abstract
In a hand tool for the mixing and metered dispensing of a two-component mass, a container holding a solid component mass is mounted in a handgun-like shaped support member. A mixing chamber is aligned with and mounted on one end of the container for mixing the components of the mass. A motor in the support member drives a drive shaft extending axially through the container. A mixing worm is connected to the drive shaft and is located within the mixing chamber. A metering pump is located within the support member for delivering a liquid component of the mass from a tank. The metering pump is a hose pump powered by the drive shaft. A conveying helix is positioned on the drive shaft in the container. Accordingly, since the drive shaft powers the metering pump and the conveying helix, a fixed mixture ratio of the solid and liquid components is delivered into the mixing chamber independently of the quantity dispensed. The mixed components flow out of the mixing chamber through a dispensing nozzle.
