  • Patent number: 9795070
    Abstract: A dispensing pump, and more particularly, a valve accelerating type dispensing pump that may be used in a process of manufacturing an electronic product and may dispense an accurate amount of a liquid, such as a liquid synthetic resin, at high speed. The valve accelerating type dispensing pump can descend a valve rod at high speed and thus can dispense a liquid with high viscosity at high speed. The valve accelerating type dispensing pump can dispense an accurate amount of a liquid at high speed. Also, the valve accelerating type dispensing pump can dispense a liquid having high viscosity at high speed due to a fast descending speed of a valve rod.

  • Patent number: 9545644
    Abstract: A dispensing system includes a pump mechanism that has a liquid chamber, a liquid piston for delivering fluid to a mixing chamber, and a valve component biased to close the outlet from the liquid chamber. The pump mechanism also has an air chamber, and an air piston for delivering air to the mixing chamber. A bore allows passage of a mixture of the air and the liquid from the mixing chamber to a dispensing tube. A pump actuator moves the air piston and the liquid piston to propel a dose of the mixture of the air and the liquid through the bore and into the dispensing tube and to collapse a draw-back chamber. The draw-back chamber expands to draw the mixture of the air and the liquid from the dispensing tube into the draw-back chamber. The valve component is biased to close the first outlet before the draw-back chamber expands.
