ABSTRACT:
A gas mixing/supplying device and a method includes of introducing a gas into a high-viscosity material. The method the steps of effecting a first suction stroke in which the piston (25) is moved in the cylinder (27); supplying a high-viscosity material to the cylinder, using a suction force in the cylinder generated in said first suction stroke; stopping the piston after the first suction stroke; effecting a second suction stroke in which the piston is moved in the cylinder after the supply of the high-viscosity material; supplying a gas to the cylinder, using a suction force in the cylinder generated in the second suction stroke; effecting a pressurizing stroke in which the piston is moved in the cylinder after completion of the supply of the gas; and effecting a discharge stroke in which the high-viscosity material and the gas are discharged into a conduit. Then, the high-viscosity material is foamed under atmospheric pressure.
