ABSTRACT:
A bite valve for drinking liquids from a hydration system, the bite valve having a hollow deformable impervious body with a receiving opening fluidically connectable to an outlet of the hydration system for receiving liquids and a dispensing opening adapted to selectively dispense received liquids. A resilient piston positioned within the hollow deformable body, the resilient piston having a plug normally blocking the dispensing opening, and a resilient bifurcated member having a longitudinal dimension and a lateral dimension, adapted to shorten its initial longitudinal dimension when lateral force is exerted on its lateral dimension, and regain its initial longitudinal dimension when the lateral forces are not exerted, so when a lateral force is exerted on the resilient bifurcated member the piston is retracted inwardly allowing liquid to flow through the dispensing opening.
