  • Liquid dispenser
    Patent number: 4946100
    Abstract: A liquid dispensing system for selectively dispensing a plurality of different liquids includes a separate reservoir for each of the fluids, and a separate nozzle for dispensing each of the fluids. A separate hydraulic dispensing system having a cylinder containing a piston is connected to each reservoir and nozzle for removing fluid from each reservoir and feed the liquid to the respective nozzle. A single hydraulic operation system including a cylinder containing a piston is connected to each dispensing cylinder to selectevely operate the piston in each dispensing cylinder. The piston in the operating cylinder is operated by an electric motor having a threaded shaft, a nut on the threaded shaft and a drive arm of the nut. The drive arm is connected to the piston in the operating cylinder to move the piston a selected distance and thereby dispense a selected amount of liquid from a selected nozzle. Alternatively, the drive arm on the nut can be connected directly to the piston in the dispensing system.
