Metering pumps for an aerosolizer |
摘要 |
An apparatus to make a certain volume of liquid available for atomization comprises a container adapted to hold a liquid, and a piston pump. The piston pump comprises a piston member and a valve body, with the piston member being slidable within the valve body. Further, the valve body functions with the piston member to define a metering chamber. In this way, the metering chamber is adapted to be filled with liquid from the container when the piston member is moved to a filling position, and the piston pump is adapted to dispense a known volume of the liquid from the metering chamber when the piston member is moved to a dispensing position. |
