Abstract
The current invention is a linearly regulated gas valve for a gas burner, utilizing a central plug to control the gas flow. This valve has the capability of providing a smoothly increasing or decreasing gaseous flow between the highest setting and the lowest setting, allowing the user a wide choice of settings for any particular food that is being prepared on the gas burner. This invention also does not require an additional jet to operate at the low setting.
Claims7
A linearly regulated gas valve, comprising:
- a) a gas valve body, said gas valve body having a gas valve chamber defined therein, a valve inlet, said valve inlet having a inlet conduit, said inlet conduit communicating with said gas valve chamber, a valve exit, said valve exit having an exit conduit, said inlet conduit and said exit conduit being aligned co-incident with a longitudinal axis, said gas valve chamber in said gas valve body having a bottom portion, said bottom portion having a groove defined therein, said gas valve body further having a diagonal channel defined therein allowing said gas valve chamber to communicate with said exit conduit, in said valve exit, said diagonal channel having means to prevent flammable gas from leaking from said gas valve body;
- b) said inlet conduit being separated from said valve chamber by a partition, said partition having a penetration defined therein, said penetration allowing said inlet conduit to communicate with said valve chamber;
- c) a gas valve plug, said gas valve plug having a second longitudinal axis defined therein, said gas valve plug having a shape complimentary to said gas valve chamber and having a lower chamber defined therein, said lower chamber penetrating halfway through said gas valve plug, said gas valve plug additionally having an upper cavity defined therein, said upper cavity being separated from said lower chamber by a partition, said upper cavity having a wall, said wall having a first slot defined therein, said slot allowing a control means to turn said gas valve plug when said gas valve plug is installed into said gas valve body;
- d) said gas valve plug having a first hole defined therein, said first hole allowing communication between said inlet conduit of said valve inlet and said lower chamber of said gas valve plug, said first hole providing maximum flow between said valve inlet and said gas valve plug, said gas valve plug having a diagonal slot defined therein, said diagonal slot being located towards said first hole and being defined at an angle to said second longitudinal axis of said gas valve plug, said diagonal slot communicating with said penetration in said partition in said gas valve body;
- e) said gas valve plug having a second channel defined therein, said second channel being ninety degrees to said second longitudinal axis, said gas valve plug having a connecting hole defined therein and positioned in said second channel, said second hole communicating with said penetration in said gas valve body;
- f) a valve cap, said valve cap having a central hole defined therethrough, a shoulder bushing being positioned within said central hole of said valve cap and being attached to said valve cap, a control means, said control means being inserted through said valve cap and therefore said shoulder bushing;
- g) said valve cap has a circumferential groove defined therein, said central groove being positioned co-axially with said central hole, said central groove providing a surface for means to control said gas valve to bear against;
- h) said circumferential groove of said valve cap has an off position slot, and a maximum position slot defined therein;
- and
- i) a biasing means, said biasing means forcing said control means to bear against said groove in said valve cap.
