Abstract: The invention relates to a spark wheel type gas lighter comprising a lighter body, a reservoir, a valve permitting gas to leave the reservoir, an ignition system comprising a pyrophoric flint co-operating with a spark wheel and a spring maintaining the flint against the spark wheel, a lever pivotally mounted on an axis essentially parallel to the axis of rotation of the spark wheel and co-operating with the valve and the axis of the lever is mounted movably with respect to the body of the lighter between an active position permitting the operation of the valve mounted on the reservoir and a rest position in which action on the lever does not permit operation of the valve, the spark wheel can be displaced with respect to the body of the lighter, and operate the lever in its movement, and elastic means act on the lever and/or on the spark wheel to return them to a position of rest in which the lever does not act on the valve.

Abstract: A cigarette lighter for use with a volume of fuel includes a body. At least one projection extends from the body and defines at least one opening, which includes a first area bounded on at least one side by a curved leg and a second area bounded on at least one side by a flat leg. An ignition system includes a flint, a knurled wheel, and at least one elongated stub coaxial with the knurled wheel. A cross-section of the at least one stub has at least one flattened face.

Abstract: A reservoir for gaseous fuel in a liquid phase includes an elongate cylindrical wall closed by two transverse end walls, a lower end wall provided with a draw-off orifice and an upper end wall equipped with a draw-off member such as a valve and a pressure reducer, and has an internal volume occupied by an absorbent medium. A chamber is provided above the absorbent medium, between the absorbent medium and the upper end wall of the reservoir. The volume of the chamber is at least equal to the volume of the liquid fuel not absorbed by the absorbent medium after turning the reservoir upside down. The draw-off orifice is equipped with a draw-off tube of fine bore, which is positioned upstream of the pressure reducer and is housed axially in the chamber. The length of the draw-off tube is at least equal to the height of the fuel in the liquid phase that may be in the chamber when the reservoir is in an inverted position.

Abstract: The means for neutralizing the lever for opening the burner valve consist of a pusher mounted so as to slide under the lower face of the rear end of the control lever and movable between a withdrawn active position in which a part integral with the body of the lighter is situated just below it, making any maneuver of the control lever impossible in the direction for opening the valve, and an advanced and nonobstructing position, in which the aforementioned part of the body of the lighter is no longer in the path described by the pusher when the control lever is maneuvered in the direction for opening the valve, making this maneuver possible, means being provided for ensuring that the pusher is momentarily kept in the nonobstructing position before actuation of the control lever and other means being provided to ensure that it returns to the active neutralization position immediately after this actuation.

Abstract: A childproof lighter has a housing adapted to hold a supply of combustible fuel, a valve in the housing between the nozzle and the supply and actuatable to emit the fuel, and an igniter on the housing adjacent the valve. An actuating element is depressible longitudinally downward between an upper position and a lower position and is coupled to the valve and igniter for actuating same when depressed into the lower position. This actuating element is formed with a longitudinally downwardly projecting skirt itself formed with a longitudinally projecting and laterally elastically deflectable tongue in turn formed with a laterally projecting catch formation forming a longitudinally downwardly directed stop surface displaceable on elastic deformation of the tongue between an outer position and an inner position.

Abstract: A lighter has a body forming a reservoir holding a supply of a flammable gas under pressure and a valve on the body openable to allow the gas to escape from the reservoir as a jet extending along an axis and normally urged axially open by the pressure of the gas. A pressure reducer is provided on the reservoir upstream of the valve and an igniter on the body can light the jet when the valve releases it. An operating lever pivoted about an axis orthogonal to the jet axis has a front end normally bearing axially downward on the valve and a rear end. A first spring braced between the body and the lever rear end rotationally biases the lever front end downward on the valve with a predetermined first force greater than the force exerted oppositely on the valve by the gas.

Abstract: A lighter has a body forming a reservoir holding a supply of a flammable gas under pressure, a valve on the body openable to allow the gas to escape from the reservoir as a jet extending along an axis and normally urged open by the pressure of the gas, and an igniter on the body for lighting the jet. An operating lever pivoted on the body about an axis orthogonal to the jet axis has a front end normally bearing axially downward on the valve and a rear end and is formed as front and rear segments joined only by a central elastic web permitting the segments to move limitedly elastically relative to each other. Stops limit relative movement of the lever segments. A spring braced between the body and the lever rear end rotationally biases the lever front end downward on the valve with a predetermined first force greater than the force exerted oppositely on the valve by the gas.

Abstract: A reservoir for a gaseous combustible stored as a liquid has a substantially closed container having a side wall, an upper wall, and a bottom wall, the upper wall is formed with an outlet port. A porous mass generally fills the container and is saturated with a body of the combustible in liquid condition. A dip tube has an upper end joined to the upper wall at the outlet and a lower end formed with at least one orifice of such small size that a meniscus/interface is formed between the liquid and gaseous phases at the orifice. The tube is formed with a crosswise web at its lower end and the orifice is above this web on a side of the tube. Furthermore the container is generally cylindrical and centered on an axis, the outlet and tube is coaxial with the container.

Abstract: This lighter is of the type having on its housing in which is provided a reservoir containing the gas in liquid form a head comprising in addition to the burner valve (10) connected with the reservoir via a pressure reducer an igniting mechanism comprising control means (4) for the opening of the burner valve (10) and means for making sparks (2, 3, 4, 8, 11) and in which associated with the igniting mechanism is means (8) for neutralizing this mechanism and displaceable between an active neutralizing position for the igniting mechanism and a retracted position, these neutralizing means (8) being displaceable manually by the user from their active position to the retracted position. The neutralizing means (8) of the igniting mechanism are normally maintained in the neutralizing position and are in addition set up so as to be automatically returned to the neutralizing position after actuation of the igniting mechanism.
