Abstract:
An earthquake gas valve that uses an electro-mechanical battery powered actuation method to automatically close a gas valve when the movement caused by an earthquake is perceived, or if an extremely high temperature is perceived. A gear motor is activated by a plurality of shake switches which in turn cause a motor driven radial rack to rotate. The rack terminates in a closure plug which obstructs the gas outlet opening and prevents gas from entering the house or office when an earthquake occurs. A timing circuit delays the activation of the closure plug to make sure that the motion has been caused by an earthquake and not by an accidental brief jarring action. In one embodiment, the closure mechanism can be activated remotely by receiving a transmitted signal which is picked up by a receiving device within the valve enclosure, or the valve can send a signal to a central remote location telling of its open or closed condition.

Claim (Index 6):
An earthquake gas valve comprising:\n a main housing; a housing top cover; a pair of housing clamps; a rack member gasket; a housing gasket; a radial rack member; a gear motor; a battery; a drive gear; a gas closure member; a linkage arm; a separator plate; a printed circuit board; a plurality of shake switches; a microprocessor; said housing top cover attached to said main housing via said housing clamps; said housing gasket sealing said housing top cover to said main housing sealed in an airtight manner; said separator plate isolating the lower gas flow area from the upper electromechanical storage area; said radial rack member extending from said upper housing area to said lower housing area and through said rack member gasket; said drive gear attached to the shaft of said gear motor; said drive gear engaging said radial rack; said radial rack terminating at one end in said gas closure member; said closure member being made of a resilient material; said linkage arm attached to said radial rack member and pinned to a fulcrum hinge point located under said separator plate; said main housing including one or more gas inlet apertures and one gas outlet aperture; said battery capable of powering said gear motor; said gear motor caused to rotate when said shake switches sense physical movement and turn on said motor causing said gas closure member to fully obstruct said gas outlet aperture; and said microprocessor including a timing circuit that delays the activation of said gear motor for a pre-determined period of time to ensure that the movement is being generated by an earthquake and not by an accidental brief motion occurrence.
