Foot Support Systems Including Fluid Movement Controllers

A footwear foot support system, comprising:

• a foot support bladder;
• a fluid source container;
• a manifold body defining an internal chamber;
• a first port placing the fluid source container in fluid communication with the internal chamber;
• a second port placing the foot support bladder in fluid communication with the internal chamber;
• a third port in fluid communication with the internal chamber and with an external environment;
• a first valve controlling fluid flow between the internal chamber and the fluid source container through the first port, wherein the first valve includes a first valve activator;
• a second valve controlling fluid flow between the internal chamber and the foot support bladder through the second port, wherein the second valve includes a second valve activator;
• a third valve controlling fluid flow between the internal chamber and the external environment through the third port, wherein the third valve includes a third valve activator;
• a movable cam at least partially located within the internal chamber, wherein the movable cam includes:
• (a) one or more first valve activator surfaces that interact with the first valve activator to change the first valve between a closed configuration and an open configuration when the movable cam is moved, (b) one or more second valve activator surfaces that interact with the second valve activator to change the second valve between a closed configuration and an open configuration when the movable cam is moved, and (c) one or more third valve activator surfaces that interact with the third valve activator to change the third valve between a closed configuration and an open configuration when the movable cam is moved.

A fluid flow control system for an article of footwear, comprising:

• a manifold body defining an internal chamber;
• a first port in fluid communication with the internal chamber;
• a first valve controlling fluid flow through the first port, wherein the first valve includes a first valve activator;
• and
• a movable cam at least partially located within the internal chamber, wherein the movable cam includes one or more first valve activator surfaces that interact with the first valve activator to change the first valve between a closed configuration and an open configuration.
