ABSTRACT:
A safety device for preventing uncontrolled burning in wick-fed liquid fuel burners of the type where a removable tank (60) feeds a fuel chamber (40), which supplies the fuel to a wick (54), via a sump opening in the upper surface of the chamber (40). A plate (32) in the removable tank (60) contains a seat (90) and a needle (76), which, in conjunction with a compartment (80), a float (88), a lever (82), and an orifice (34), restrict fuel egress from the tank. A fill tube (44) traverses the plate. An opening (104) in the plate, along with a face (102) attached to an arm (96), allows air egress from a chamber (30) in the tank during fueling of the tank, but prevents fuel egress from the chamber when the tank is inserted in the burner. Fuel flow through the plate (32) is regulated by the movement of a float (88) attached to a lever (82), which is operatively connected to a needle (76) and a seat (90). Fuel flows through a seat (90) into a compartment (80), and begins to egress through an orifice (34). Fuel accumulates in that compartment (80), urging a float (88) and a lever (82) upward causing a needle (76) to move upward, reducing the flow through a seat (90). An equilibrium is established, in which the flow rate through a seat (90) equals that through an orifice (34). This flow rate is not affected by the depth of the fuel above the plate (32), nor by the pressure in the tank (60).
