Title: Innovations by James Mathew Amaral
Introduction
James Mathew Amaral is an accomplished inventor based in Morgan Hill, California. He has made significant contributions to the field of tire technology, particularly focusing on tubeless tire inflation systems. With a total of five patents to his name, Amaral's work showcases his dedication to enhancing the functionality and safety of tire systems.
Latest Patents
Amaral's latest patents include an innovative inflation valve for tubeless tires. This tire inflation valve features anti-rotation elements and an external valve seat. It consists of a valve body, a valve stem that extends through the valve body, and anti-rotation features located within the valve body. The design allows the valve stem to move relative to the valve body, enabling a resilient seating surface at the proximal end of the valve stem to displace relative to the valve seat formed by the valve body. The anti-rotation features may include various configurations such as complementary slots and protrusions, keyways with protruding ridges, or channels with lateral protrusions.
Another notable patent is the inflation system for tubeless tires. This system includes a valve body that defines a cavity with both proximal and distal openings. A valve stem extends through this cavity and features a plug at its proximal end. The proximal opening is defined by a beveled surface, which has an outer diameter larger than the inner diameter of the valve body. The valve can transition between a closed position, where the plug's resilient surface seals the cavity, and an open position, where the plug is spaced from the beveled surface to unseal the cavity.
