Publication number: 20130008579Abstract: A groove is positioned within the bending region of the first tire sidewall and deforms segment by segment within the rolling tire footprint. An air tube positioned within the sidewall groove is in contacting engagement with groove sidewalls and resiliently squeezes and collapses segment by segment as the groove constricts segment by segment within the rolling tire footprint. A series of adjacent projecting ridges extend from a groove sidewall segment into the groove air passageway, the projecting ridges operatively positioned to vary the applied pressure on the air tube increase the air pressure within the air tube passageway as the air tube rolls segment by segment with the tire through tire footprint. The series of projecting ridges are constructed having a variable amplitude and/or spacing frequency in a direction of air flow within the air passageway to increase the pressure applied to the air tube and air pressure of the air flowing through the tube passageway.Type: ApplicationFiled: July 8, 2011Publication date: January 10, 2013Inventor: Andres Ignacio Delgado

Patent number: 8322036Abstract: A method of constructing a self-inflating tire assembly includes molding in an air tube-receiving groove within a green tire carcass wall, the groove having an access opening, primary internal groove chamber and a secondary expansion groove chamber adjacent to and communicating with the internal groove chamber. A groove partial passageway is molded with the groove at a prescribed groove outlet location and extends from the groove partially through the tire carcass wall toward the tire cavity. A tire carcass wall barrier of reduced section between the partial passageway and the tire cavity is removed in a post-cure operation to create a through-bore from the groove to the tire cavity. A pump assembly inserts into the tube-receiving groove in a post-cure procedure with an outlet passage tube from a pump assembly outlet device extended through the through-bore to the tire cavity.Type: GrantFiled: November 22, 2010Date of Patent: December 4, 2012Assignee: The Goodyear Tire & Rubber CompanyInventors: Andres Ignacio Delgado, Christopher David Dyrlund, Mark Anthony Sieverding
