Abstract
A pressure relief device (100) for an inflatable tire comprises a body (102) having a chamber (116) therein and pressure relief mechanism for releasing air when the air pressure in the chamber exceeds a first predetermined pressure level. A conduit (108; 208) inter-connects an air inlet (110; 210) with an air outlet (112; 212). The conduit (108; 208) is provided in a pin (104; 204) arranged to slide axially in a passageway (106) in the body, the pin (104; 204) extending from the air inlet (110; 210) to the air outlet (112; 212) and being slidable between a first position in which it cannot release a stem of the tire, and a second position, in which it can release the stem.
Claims10
A pressure relief device for an inflatable tire, comprising:
- a body defining a chamber therein;
- an air inlet configured to connect to an inflation device;
- an air outlet configured to connect to a valve of a tire;
- a pin configured to slide axially in a passageway in the body, the pin extending from the air inlet to the air outlet and being slidable between a first position in which the pin cannot release a stem of the tire, and a second position, in which the pin can release the stem, the pin defining a conduit configured to lead air from the inflation device to the valve of the tire during inflation thereof, the conduit providing a passage in the pin, the passage in the pin comprising a transversely extending inlet section and a transversely extending outlet section;
- a pressure relief mechanism for releasing air from the chamber when the pressure therein exceeds a threshold pressure level.
