Embodiment Construction

[0033] First refer to image 3 , the fuel supply system is designed to be installed in figure 1 Portable paraffin (kerosene) heaters of the general type shown in . The fuel supply system has a replaceable disposable fuel container 1 and a storage tank (liquid fuel tank) 2 permanently installed in the heater. The storage tank 2 has a fuel supply inlet (fuel supply port) 102 provided with an adapter attachment 3 for engaging with the fuel container 1 and a wick element 4 for supplying fuel from the storage tank to a heating device provided Burner 5 in the device (refer to figure 1 ). Other means of supplying fuel from the storage tank to the burner may be used in accordance with known burner technology.

[0034] The disposable fuel container 1 comprises a container body 6 in the form of a low-cost lightweight shaped thin-walled plastic bottle, typically having a capacity of between 1 and 2 liters, pre-filled with a liquid hydrocarbon fuel ( Usually paraffin (kerosene)). Al...

Abstract

The liquid fuel burner uses a single use fuel container including a moulded plastic bottle (6) which is pre-filled with a liquid hydrocarbon fuel such as paraffin (kerosene). The bottle has a neck forming a single opening which is provided with a non-removable spring-loaded shut-off valve (9). The fuel delivery system includes a fuel reservoir (2) provided with an adapter (3) for receiving the shut-off valve (9) and incorporates a latch arrangement such as spring latches (33), (34). The fuel container incorporates a latching feature such as groove (36) for releasable engagement with the latcharrangement.

Description

technical field [0001] The present invention relates to a liquid fuel burner as used in a portable heater burning liquid hydrocarbon fuel such as paraffin (kerosene) and a coupling assembly for use therein. Background technique [0002] Portable paraffin (kerosene) heaters sometimes have a removable fuel tank that supplies fuel to a small holding or storage tank secured within the heater. Typically, the fuel tank is removed by lifting it through a door in the top of the heater, as figure 1 shown. Use a siphon to refill tanks from bulk containers (typically 20 liters) - see figure 2 . During this process, the bulk container needs to be raised above the fuel tank, which is usually accomplished by placing said container on top of a second bulk container, as shown. [0003] The removable fuel tank is provided with a spring-loaded shut-off valve that automatically closes when the tank is removed from the heater. When the refilled canister is reinserted into the heater, the ...
