Compact valve system for self-inflating tire

A self-inflating tire assembly comprising:

• a. a tire having a tire cavity, a first and second sidewall extending respectively from first and second tire bead regions to a tire tread region;
• b. said tire having a pump passageway, said pump passageway having an inlet end and an outlet end and being operative to allow a portion of the pump passageway near a tire footprint to substantially close the pump passageway,
• c. a valve device connected to the inlet end and outlet end of the pump passageway, wherein the valve device has a valve body having a first, second and third chamber, said first chamber having a first hole in fluid communication with the inlet end of the first pump passageway, said second chamber having a second hole in fluid communication with the outlet end of the pump passageway and a third chamber having a channel in fluid communication with the ambient air;
• d. wherein a first outlet passageway is in fluid communication with the tire cavity and the first chamber, and a second outlet passageway is in fluid communication with a second chamber, wherein a first check valve is positioned in the first outlet passageway to prevent flow from the cavity into the valve device;
• wherein a second check valve is positioned in the second outlet passageway to prevent flow from the cavity into the valve device;
• wherein a pressure membrane is received within the valve body, and positioned to open and close the channel.
