Abstract:
1. A combustion device for combusting a liquid fuel, the combustion device including: a fuel reservoir comprising a rigid, air-tight outer container defining an outlet opening for fuel and an inlet opening which can be connected to a source of pressurized fluid; a deformable fluid-impervious membrane which is located within the outer container and which separates the fuel reservoir into a first chamber in which the fuel can be contained and a second chamber which can be pressurized by the pressurized fluid for pressurizing the fuel within the first chamber; a burner for burning the fuel, which is elevated above the fuel reservoir; and fuel supply means which extends between the outlet opening of the outer container and the burner for conveying fuel to the burner, the pressurized fluid exerting sufficient force on the membrane and thereby the fuel in the first chamber to cause the fuel to be conveyed along the fuel supply means to the burner; and, wherein the rigid, air-tight outer container of the fuel reservoir has a base which is locatable on a ground surface, the base defining a discharge opening through which the pressurized fluid can be discharged from the reservoir and a pressure-release valve which is located within the discharge opening, the valve including a valve actuation member which is displaceable between a valve-closing position wherein the valve actuation member closes the discharge opening and a valve-opening position wherein the valve actuation member opens the discharge opening, the valve actuation member projecting from the base of the fuel reservoir such that it is acted upon by said ground surface which holds the valve actuation member in its valve-closing position, the valve including urging means which exerts a force on the valve actuation member for urging it into its valve-opening position, thereby causing the release of the pressurized fluid from the reservoir when the valve actuation member is lifted off the ground surface.
