ABSTRACT:
An apparatus is disclosed for introducing a free-flowing balancing material into a tire through a tire valve stem. The apparatus comprises a container for confining a predefined amount of free-flowing balancing material, and a flow path for pressurized air which extends from the source of the pressurized air to an air inlet, from the air inlet to a mixing chamber in communication with the container through an opening, and from the mixing chamber to an air outlet. The flow path has a pressure regulator therein, a venturi nozzle within the mixing chamber to accelerate the air flow and lower the air pressure within the mixing chamber to draw the free-flowing balancing material from the container into the mixing chamber; and a chuck for introducing the mixture of free-flowing balancing material and pressurized air from the air outlet and into a tire valve stem. The volume of the container is large enough to contain an amount of free-flowing balancing material sufficient to effect dynamic balancing of a tire and associated wheel assembly.
