DYNAMIC TIRE PRESSURE REGULATOR FOR BICYCLES

摘要

A wheel hub assembly of a bicycle wheel is disclosed that include a wheel axle, a rotary pump that may be composed of a pump housing, a pump rotor, a first fluid port configured for fluidly coupling to a pneumatic tire and a second fluid port configured for fluidly coupling to a fluid reservoir. The assembly allows for conveniently and efficiently modifying the tire pressure in bicycles at will while riding, in as many cycles as desired and without contaminating the air inside the tires.
