Abstract
Abstract A conduit is provided including inlet and outlet ends and a spray nozzle is supported from and closes the outlet end of the conduit. The inlet end of the conduit may be suitably communicated with any source of waste oil under pressure and the nozzle includes an inlet communicated with the interior of the conduit and a valve member is supported within the conduit from one end of a bellows member having its other end anchored stationary relative to the conduit. The bellows member is internally pressurized with a fluid under the desired pressure and the exterior of the bellows member is subject to the pressure of oil with the conduit. The internal pressure within the bellows member tends to extend the bellows member and position the valve member in position closing the inlet to the nozzle and when the pressure of waste oil within the conduit exceeds a predetermined pressure, the bellows member contracts and moves the valve member out of closing relationship with the inlet to the nozzle so that waste oil under pressure within the conduit may be expressed from the nozzle, suitable ignition being provided adjacent the outlet of the nozzle for igniting the waste oil discharged therefrom.
