Abstract
The present disclosure includes a combination sensor and pressure relief valve. The combination sensor and valve may be used with existing aircraft wheel systems. Wheel systems utilizing the combination sensor and valve are also disclosed.
Claims17
A combination sensor and pressure release valve, comprising:
- a housing defining at least two air exit openings and comprising a stem defining an air entry opening, wherein the stem is configured to be retained by a valve receptacle of a wheel and wherein the housing is configured to receive air from a tire through the air entry opening, wherein the stem is aligned along a longitudinal axis;
- an over-inflation pressure relief valve segment within the housing, in fluid communication with the air entry opening, and comprising a frangible disk located upstream from the at least two air exit openings and configured to rupture at a predetermined pressure such that the air flows past the frangible disk and through the at least two air exit openings in response to the frangible disk rupturing, the frangible disk comprising a planar surface aligned perpendicular to the longitudinal axis, wherein the at least two air exit openings are orientated perpendicular to the planar surface of the frangible disk;
- and
- a tire pressure sensor within the housing, aligned along the longitudinal axis, and in fluid communication with the air entry opening, the tire pressure sensor configured to sense a pressure of air received from the tire during inflation of the tire.

An aircraft wheel system, comprising:
- a wheel having a sensor receptacle;
- and
- a combination pressure sensor and pressure relief valve comprising:
- a housing defining at least two air exit openings and having a stem and an air entry opening, wherein the housing is configured to receive air from a tire through the air entry opening,
- an over-inflation pressure relief valve segment within the housing, in fluid communication with the air entry opening, and comprising a frangible disk located upstream from the at least two air exit openings and configured to rupture at a predetermined pressure such that the air flows past the frangible disk and through the at least two air exit openings in response to the frangible disk rupturing, the frangible disk comprising a planar surface wherein the at least two air exit openings are orientated perpendicular to the planar surface of the frangible disk, the planar surface extending substantially perpendicular to a longitudinal axis;
- and
- a tire pressure sensor within the housing and in fluid communication with the air entry opening, the tire pressure sensor configured to sense a pressure of air received from the tire during inflation of the tire, wherein the tire pressure sensor, the frangible disk and the over-inflation pressure relief valve segment intersect the longitudinal axis.
