Abstract
A fluid flow control valve for use in liquified gas-filled lighters or the like to limit the maximum rate of flow, and corresponding height of flame, as a function of the degree of compression of a filter mass through which the gas must flow, including simple means for varying the degree of compression and a stop to establish a predetermined maximum flow rate.
