초록

High viscosity materials are dispensed or aspirated by an assembly of cartridges having plungers reciprocally mounted within them. A device for translating rotary motion into linear motion is connected to the output shaft of a small electric motor so that operation of the motor effects linear movement of the plungers. The assembly replaces hydraulic and pneumatic systems and enables better control of the dispensing or aspirating process. In a first embodiment, a single cartridge dispenses a high viscosity material. In additional embodiments, plural cartr...
