<p>The invention concerns a safety gas valve ( 1 ) provided with a safety closure ( 23 ) and an operating lever ( 12 ) for the closure. The lever ( 12 ) is mounted mobile in rotation about an axis L in a cavity ( 34 ) circulating the gas and comprises two tabs ( 122, 123 ) extending transversely to the axis L, one driving and the other driven. The driving tab ( 122 ) drives the lever in rotation, and hence the driven tab ( 123 ) which is secured thereto, in response to a stress A when the valve is opened. The driven tab ( 123 ) enables to push back the safety closure ( 23 ) into an opening position allowing the gas to flow in the valve. If both tabs extend along respective mutually perpendicular directions, the lever ( 12 ) enables the cocking movement to return by 90 degrees. Said device reduces the thickness of the valve body, in particular for its fixing into a built-in cooking plate.</p> |
