ABSTRACT OF THE DISCLOSURE: A noncontrolling type valve for use in a gaslighter, a port- able cooking stove and other burners, which valve comprises a valve body push-fitted in a recess formed in the top plate of a gas container: and a filter positioned under the valve body to permit the gas to flow at a controlled rate. The valve according to the present invention uses a porous concave object as a fil- ter. The filter is laid on an impermeable resilient membrane. The gas invades the concave space of the porous object from the outside to flow in the valve opening. The rise of the surround- ins temperature will cause the membrane to bend yieldingly up- wards to cover the inside of the porous object, thereby prevent- ins the increase of the gas flow Passing through the porous ob- ject over a predetermined flow rate.
