Abstract:
1. A bite valve for a hydration system, comprising: a body comprising a body channel configured to flow a fluid; a sheath configured to attach to the body, the sheath comprising a sheath channel extending from the body to a sheath opening; a seal post positioned within the sheath channel and configured to be movable with respect to the sheath and the body between a sealed position and an unsealed position, wherein the seal post comprises an inclined surface configured such that an approximately transverse force applied against the inclined surface causes the seal post to move from the sealed position to the unsealed position; and a first seal and a second seal, wherein the first seal is configured to selectively restrict and allow fluid flow from the sheath channel through the sheath opening, and the second seal is configured to selectively restrict and allow fluid flow between the body channel and the sheath channel, and wherein the inclined surface is positioned between the first and the second seal; wherein the first seal and the second seal are configured to restrict fluid flow between the body channel and the sheath opening when the seal post is in the sealed position, and to allow fluid flow between the body channel, the sheath channel, and through the sheath opening, when the seal post is in the unsealed position.
