I decided to tear this pump down and demonstrate it before binning it, I’ve already done a few vids on rotary compressors before but theirs no harm in doing more detailed ones Its from a single phase 240V powered 7.1Kw split unit that was scrapped because of a bad compressor motor.(short to earth)

Project: Build a stirling engine that can do some usefull work. This is an on-going project, the engine is not yet finished but it works! Built around 4 stud bar colums, the displacer cylinder is a stainless pasta tin, the piston is an old footpump cylinder (with a new cast polyester piston). Old saucepans form the furnace (bottom) and the water jacket (at the top) which creates the heat differential between the two ends. The oscilating piston is connected via bit of flexible garden hose, and the flywheel is cast iron. The plan is to use this to pump water for the garden pond, using anything that burns as fuel. The bricks form a makeshift fire box as this is the first time the engine has run on solid fuel, in this case a small wood fire. Thanks for viewing, I will upload more as the engine develops.

I was thinking about the reason why these rotary compressors have reed valves on the output when theoretically they shouldn’t be needed, and after a quick test with an air compressor, it’s quite apparent why: Without the valve, the high discharge pressure would turn the compressor into a motor, and would spin it up to high speed in reverse, potentially damaging the motor or compressor.

Only if 2 compressors are running side by side a sound comparison is possible for the viewer. My invented totally oil-free axial piston compressor principle is not only much more silent as any conventional compressor, but also more powerful. Both is made possible by the water jacking system (both rotors running in water).
