Abstract: A fuel oil flow control device has a chamber in which a constant oil level is maintained by a float-controlled inlet valve. If the valve closes at an above normal oil level, the float must be secured in its raised position until manually released by a manually resettable safety device. This device comprises a generally Z-shaped lever comprising an L-shaped operative arm pivoted at its upper end and a lateral counterbalance arm. The lever is disposed adjacent the float and so immersed in the oil that as the oil level exceeds normal, the increased buoyancy of the lever causes it to tilt into locking engagement with the float.
