Abstract

This invention reveals an improved gas valve with a thermoelectric security device that has a shortened distance from the gas inlet to the front of an appliance, enabling the overall size of the appliance to be smaller than normal for this type of device. The current invention achieves this goal by reversing the gas inlet and outlet and hence the gas flow through the gas valve.

Claims (7)

1. An Improved Gas Valve with a Thermo-Electric Security Device, comprising:

a. a gas valve, said gas valve having a gas inlet and a gas outlet, said gas inlet being dimensionally closer to a gas valve knob than said gas outlet to have the adaptability to be utilized with different gas intet valve types,

b. said gas valve further having a gas valve body, said gas valve body having a gas valve plug, said gas valve plug being positioned within said gas valve body and having a valve seat defined therein, said valve seat being positioned in proximity to said gas outlet, said gas valve further having a receiver hole defined therein, said receiver hole communicating with said gas outlet, said gas valve plug having means to allow communication between said gas inlet and said gas outlet when said gas valve plug is rotated by a valve spindle, said valve spindle being attached to said gas valve knob;

c. said valve spindle has a driver pin attached, said driver pin driving said valve plug so that flammable gas is not permitted to enter said gas valve plug unless said gas valve knob is axially pressed in and said gas valve plug is rotated coincidentally to an orientation allowing communication between said gas valve plug and said gas inlet allowing flammable gas to thereby enter said gas valve plug;

d. a valve disc, said valve disc being slidably mounted on a spindle, said spindle being attached to a magnet insert, said valve disk being biased against said gas valve body and being positioned in said valve seat preventing flammable gas to thereby exit, and

e. a thermo-electric safety device means, where said thermo-electric safety device means generates sufficient thermocurrent to cause said magnet insert to maintain said valve disc in an open position, allowing flammable gas to flow through said gas valve plug and through said gas outlet, wherein said inlet being dimensionally closer to said gas valve knob than said gas outlet to prevent gas from entering said thermo-electric safety device means when it is closed and said valve plug is still in an open position.

2. The gas valve, according to claim 1 , in which the flammable gas inside the gas valve plug can only flow to the valve seat of the magnet insert when the gas valve is in the open position, while the valve seat of the magnet insert is held in a closed position by the absence of thermocurrent.
