Abstract
An apparatus for regulating air pressure level in a tire is provided. The apparatus includes a housing attached to the tire; a piston located inside the housing, coupled to the housing via a spring; a one-way valve; and locking elements located at a specified location along the housing, wherein the piston is configured to move towards a first end of the housing responsive to an imbalance between centrifugal force applied to the piston due to angular speed of the tire and force applied to it by the spring, wherein the locking elements are configured to lock the piston at the specified location whenever the tire reaches a predefined angular speed, and release the piston once the angular speed of the tire crosses a predefined threshold, so that the piston moves towards a second end of the sleeve producing an air pulse, conveyed by the one-way valve into the tire.
