Abstract
A valve for a gas lighter wherein an elongated support body of low thermal conductivity is clamped in a tubular member forming a valve seat at its upper end to lock a flame-height-controlling filter in place below this valve seat. The improvement resides in the formation of the thermally conductive burner-carrying member with a tubular apron, skirt or sleeve which is fitted over the thermally conductive valve member and slidingly guided therein to press a valve body (rubber gasket or flap valve) against the valve seat. The gas passage in the burner member is formed only in the upper end thereof, while the apron extends into the well beyond the filter.
Claims10
A valve for a gas lighter comprising:
- a housing formed with a well communicating with a fuel reservoir;
- an axially elongated tubular valve member received in said well and having one end anchored therein and another end formed with a valve seat surrounding an orifice;
- a tubular filter-support member received in said valve member and coaxial therewith;
- a pressure-regulating filter clamped between said members for regulating the flow of gaseous fuel through said orifice;
- an elongated burner member formed at one end with a burner nozzle and a passage communicating between said orifice and said nozzle, and at its opposite end with an elongated cylindrical skirt slidingly engaging the exterior of said valve member;
- and
- a valve body on said burner-member engageable with said seat for blocking flow from said orifice to said passage, said passage extending only over a portion of the length of said burner-member.
