Patent ID: 7497685

Claim:
A wick-holder assembly, comprising: a wick-retention member for retaining a wick in an operative position extending from a base portion; and a heat-conductive element extending from the base portion, wherein the heat-conductive element comprises a first portion made substantially of a first material and a second portion made substantially of a second material, the first material and second material comprise materials of different thermal expansion coefficients, and a portion of the heat-conductive element is arranged to move in response to a flame disposed on the wick; wherein the base portion is adapted to be disposed on a support surface therefor such that a capillary space is formed therebetween that extends to the wick, and wherein the movement of the heat-conductive element in response to the heat generated by the flame affects a dimension of the capillary space and thereby regulates flow of a fuel through the capillary space to the wick.
