Publication number: 20240102573Abstract: A tire inflation valve having anti-rotation features has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and anti-rotation features disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body. The anti-rotation features may include a complementary slot and protrusion, a keyway and complementary protruding ridge, and/or complementary channels and lateral protrusions.Type: ApplicationFiled: September 7, 2023Publication date: March 28, 2024Inventors: Brett Robert COURTNEY, James Mathew AMARAL, Nick ANDERSON, Jon WOOD

Patent number: 11904644Abstract: An inflation valve for a tubeless tire may include a valve body defining a cavity having a proximal opening and a distal opening. A valve stem extends through the cavity and includes a plug at a proximal end of the valve stem. The proximal opening of the cavity is defined by a beveled surface, and an outer diameter of the beveled surface is larger than an inner diameter of the valve body. The valve is transitionable between: a) a closed position, where a resilient surface of the plug engages the beveled surface to seal the cavity, and b) an open position, where the resilient surface of the plug is spaced from the beveled surface to unseal the cavity.Type: GrantFiled: May 24, 2022Date of Patent: February 20, 2024Assignee: Santa Cruz Bicycles, LLCInventors: Brett Robert Courtney, James Mathew Amaral

Patent number: 11338632Abstract: An inflation system for tubeless bicycle tires may include a valve, a sealant canister, a pump head, and/or a valve core adapter. The valve, sealant canister, and pump head may collectively facilitate sealant injection into a tire by a user. The valve has an external valve seat, and includes a valve body, a valve stem extending through the length of the valve body, and a retaining mechanism for the valve stem disposed interior to the valve body. The valve stem is configured to move relative to the valve body, such that a resilient seating surface disposed at a proximal end of the valve stem is displaced relative to a valve seat formed by an exterior surface of a proximal end of the valve body.Type: GrantFiled: February 23, 2021Date of Patent: May 24, 2022Assignee: Santa Cruz Bicycles, LLCInventors: Brett Robert Courtney, James Mathew Amaral
