Abstract
Apparatus and associated methods relate to a pneumatic distribution system having pneumatic pump that exhausts into a common plenum that is in fluid communication with a plurality of flow controllers. In an illustrative embodiment, a system controller may coordinate the operation of the one or more pneumatic pumps and the plurality of flow controllers to provide air pressure control to a system of pneumatic chambers. In some embodiments, one of the plurality of flow controllers may be configured to provide fluid communication with an ambient atmosphere so as to permit a fluid path from a pneumatic chamber connected to another flow controller to the ambient atmosphere via both flow controllers and the common plenum. In an exemplary embodiment, the system controller may advantageously control the air pressures in a plurality of pneumatic chambers independently of one another using coordinated control of the pump and flow controllers.
