Title:
SELF-INFLATING TIRE
Document Type and Number:
Japanese Patent JP2013049413
Kind Code:
A
Abstract:

To assemble a self-inflating function that self-inflates a tire into a tire.

A self-inflating tire assembly includes an air tube connected to a tire and defining an air passageway; and the air tube is composed of a flexible material operative to allow an air tube segment opposite a tire footprint to flatten, closing the passageway, and resiliently unflatten into an original configuration. The air tube is sequentially flattened by the tire footprint in a direction opposite to the tire rotation direction to pump air along the passageway to an inlet device 44 for exhausting from the passageway or to an outlet device 46 for directing into the tire cavity. The inlet device is positioned within the annular passageway 180 degrees opposite the outlet device in such a manner that sequential flattening of the air tube by the tire footprint effects pumping of air along the air passageway with the tire rotating in either a forward or reverse direction of rotation.
