YESSSSS. It’s taken so much work but yes! IT WORKS! Thanks for watching.

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)

Just got this one running. Don’t see too many of them. Sold by Mongomery Ward and dates from the 1930’s.

A few ppl have asked for more info on using a fridge compresssor as an air pump in the past so I thought I’d show y’all my silent compressors to give an idea on how to construct one. The most important thing is a pressure regulator and cut-out switch to ensure the tank dosn;t over pressurize and burst. these compressors can put out a lot of pressure. The Tandem SC15’s that i have as a permanent workshop compressor barely become warm when charging the tank from dead flat to 100 PSI, they are rated at roughly 3/4 HP each and have no trouble seating tire beads, spray painting or running a small sand blaster.

The MinhNguyen’s RPE S2 produces 36 strokes (9 power strokes per rotor rotation) per revolution of the rotor (4 strokes per chamber times 3 chambers, and 3 times per chamber), as opposed to 2 strokes for each crankshaft rotation of a single-cylinder single acting piston engine, wich as correlative to a single rotor is in some ways equivalent to a eighteen-cylinders reciprocating engine (V18). MinhNguyen RPE S2 rotary piston engine has Just on center, then the piston system is the Fly-wheels, accumulates kinetic energy (continuous and entire) (Continued). Note: The piston system can be has n Poles as correlative to radius of engine and width of the Poles (n=3, n=4, …). I am the sole designer of this invention.

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.

This is a 2 cylinder Australian made refrigeration compressor, made by Kirby Manufacturing – Australia. I removed it from a scrap condensing unit used on an IGA supermarket meatcase. This one is similar to a 3 cylinder Kirby compressor that I scrapped 12 months ago, after it ran dry of oil (very little remained in crank case, mixed with melted plastic from the polypropylene splash shield) and subsequently overheated to the point of throwing the no2 con rod, jamming up and burning the motor windings out (no motor protector was fitted)

The MINH NGUYEN RPE S.2-SC has split-compression principle. It can achieve a performance with high specifications [Wich as correlative to a single rotor is in some ways equivalent to a eighteen-cylinder reciprocating engine (V18)}, and consumes less fuel. This engine can be designed with a structure that can adjust the compression ratio when running.. And the principle of this rotary engine can be developed into: _ Gasoline, Diezen fuel, Hydrogen fuel, … _ Water fuel, … I am the sole designer of this invention, and declare it to be for a public domain. – - – - – - – - – - Inventor: MINH NGUY?N (NGUY?N MINH) Address : 446/1 Phan Xích Long street, ward 2, Phú Nhu?n district, HCM city, VI?T NAM
