ABSTRACT:
An improved injection apparatus is disclosed comprised of a first motor and a second motor, each motor having a shaft. First and second needles are located substantially perpendicular to the first and second shafts, respectively. When the first and second shafts rotate, the first and second needles, respectively, move up and down. The first and second shaft rotate in opposite directions. The first needle and second needles can be surrounded by first and second needle tubes, respectively. The first and second needle tubes can be mounted to a device housing. The first and second needles each preferably has a portion that lies inside its needle tube and a portion that lies outside its needle tube. First and second sources of liquid and first and second conveying tubes are provided. The first and second conveying tubes are connected to the first and second needles, preferably at a side arm inside the respective needle tubes. The first and second needles are preferably hollow. Preferably liquid flows from the first source of liquid to the first conveying tube then into the hollow first needle. Similar liquid flow occurs for the second needle. The first and second conveying tubes are connected to first and second meters which measure how much liquid is being fed into the first and second needles from the first and second liquid sources.
