Abstract
An in-line pump assembly attachable to a hydration bladder includes an electrically driven pump held in a casing and placed in the flow of hydrating liquid. The pump connects to the outlet of the hydration system. Bulbs at the respective ends of a switch line hold an essentially incompressible liquid. Pinching a bite valve bulb on the output end of the drinking tube cause a switch line bulb on the other end of the switch line to expand, closing a pressure switch and causing the pump to pump liquid from the hydration bladder through the drinking tube. Releasing the bite valve bulb reduces the pressure in the switch bulb, disengaging the switch and stopping the flow of liquid. The in-line pump assembly may be connected to a preexisting hydration system through an adapter.
