<p>The sealed oil vessel has an air inlet to build up pressure to carry the oil along the various feeds to the jets; while non-return valves in the feeds ensure the feeds are constantly loaded. Air is fed separately to the jet heads to carry the oil in fine droplets to the needles or other moving parts. The design reduces air and oil consumption and prevents lubricating oil bouncing off the lubricated parts.</p> |
