Patent ID: 7387134

Claim:
A fire safety fluid flow device for engagement with a Schrader valve including a sliding valve having an open position for allowing fluid flow through the Schrader valve and a closed position for preventing fluid flow through the Schrader valve, the fire safety fluid flow device comprising: a housing having a fluid path therethrough, the housing having a pressing member and a thermal member; the pressing member being located within the housing, the pressing member pressing against the sliding valve of the Schrader valve when engaged therewith to move the sliding valve to the open position from the closed position to allow fluid flow through the Schrader valve; the pressing member continuing to maintain the sliding valve in the open position when the device is below a predetermined temperature and connected to the Schrader valve; and the pressing member being configured to no longer press against the sliding valve of the Schrader valve at and above the predetermined temperature to allow the sliding valve of the Schrader valve to slide to the closed position to thereby stop fluid flow through the Schrader valve; wherein the pressing member includes at least a portion of the fluid path; wherein the thermal member abuts, but is not connected to, an outside surface of the pressing member when the device is below the predetermined temperature to allow the pressing member to continue to maintain the sliding valve in the open position; and wherein the pressing member is unable to be removed from the housing both above and below the predetermined temperature.
