A Mechanical Lubricator is a device used in Steam Engines to force lubricating oil into the cylinder(s) against the prevailing steam pressure.
I've spent almost two years and tried about 7 different designs. But most of the designs I've tried had the same basic flaw. That is, The pressure they could deliver was proportional to the speed at which they were operated.
This is serious problem since the higher steam pressures are generally seen at the lower speeds. If the steam pressure at the valves exceeds the pressure the lubricator can deliver - You get NO oil.
The design shown in this video clip is quite different. Sure it uses pistons and cylinders like any other. But other designs use a cam to apply pressure to the pistons and return springs to pull the piston back out of the cylinders.
This design uses springs to apply pressure to the pistons and a lever and cam to pull the pistons back. But, the cam releases the pistons instantly, making the delivery pressure totally independent of the axle speed.
