Asphalt make oil into the pump body along the mouth, full of has pulled out of the make oil into meshing in cavity teeth in space. With the rotation of the gear, between the teeth and was taken to the asphalt pressure oil chamber, because into gear meshing state, asphalt and pressure oil chamber is expelled into asphalt duct.
