FLUID METERING SYSTEM UTILIZING A ROTATABLE SHAFT

Abstract:

A dispensing apparatus for dispensing a fluid includes a dispenser body having a fluid chamber that receives the fluid, an outlet disposed on the dispenser body and that fluidly communicates with the fluid chamber, and a shaft disposed within the fluid chamber. The shaft at least partially defines a variable passage for the fluid to move therethrough from the fluid chamber to the outlet. The dispensing apparatus transitions between a plurality of dispensing configurations, and the variable passage is defined to have a different dimension for each of the plurality of dispensing configurations.
