The interior of the pot 8 is put in` communication with the interior of the reservoir I by a-curved passage member Il, one end of which is herein shown as of maximum diameter, being openV to the interior of the reservoir I, as at I2, at a level above the level of the fuel 65 is secured to the tube by any suitable cross mem bers which are'shown as including a bottom hub 39 and radial arms 60.

The member M may be provided with a handle d3 for the ro tation of the inner tube or shutter 35. The top 42 of the outer tube may be made removable, if desired, so that the device may be disassembled.
