Comment received by email from St...22nd April 2013. Comment received by email from Steve Roberts at the Middleton Railway, Leeds. Steve is restoring Sentinel 8837 (see http://sentinel7109.blogspot.co.uk/2011/08/sentinel-8837.html).<br /><br />Your displacement lubricator is no different from any I've ever seen and is not missing any part. It doesn't need your 'castellated pointy hat' thingy. <br /><br />When filling your lubricator, the first thing you always do is shut the isolation valve at the bottom. You then open the drain valve and let all the water (and any pressure) out of the lubricator before removing the filler plug. You can then fill the lubricator and, yes, the standpipe will be filled as well as the body.<br /><br />It doesn't matter as the valve is closed so oil won't pass into the steam chest. Once it is full and the filler plug replaced, you then partially open the isolation valve, but not fully. How far you open it controls the rate of feed of oil and is found by experience The oil in the tube will start to drip through the valve but can only do so if it is replaced by steam/water.<br /><br />I don't think your pointy hat will create any problems but the lubricator will function perfectly well without it.<br /><br />And so continues my education! Good to know people are keeping an experienced eye on my activities!
