SELF-PRESSURE REGULATOR TIRE MECHANISM

摘要

An apparatus for regulating air pressure level in a tire is provided herein. 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 said 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 thereto by the spring means, 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 said piston moves towards a second end of the sleeve producing an air pulse, conveyed by the one-way valve into the tire.

1. An apparatus for regulating an air pressure level in a tire comprising:
a housing coupled to said tire; a piston located within said housing, wherein said piston is coupled to said housing via a spring means and wherein the housing allows the piston to move substantially along a radius of said tire; a one-way valve; and locking elements located at a specified location along said housing, and mechanically controlled by an external piston connected to an external spring which is concentric with respect to the spring means, wherein said 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 thereto by the spring means, wherein the locking elements are configured to lock the piston at said specified location whenever said tire reaches a predefined angular speed, wherein the locking elements are further configured to release the piston once the angular speed of the tire crosses a predefined threshold, so that said piston moves towards a second end of the housing and produces an air pulse, and wherein the one way valve is configured to convey the air pulse into the tire as long as the air pressure level of the tire is below a predefined target air pressure level.
