Someone was kind enough to comment on my YouTube video from Allen today and I'm amazed.
Look up Daikin Swing compressor as well as this patent. US1137215A
Kinney pump.
I knew GE didn't invent it because there was no patent listed but I never found out what it was really called.

I took a quick look. That is an interesting design. I haven't seen the comments on You Tube.

This is all very interesting; and it brings to mind another compressor of similar name. The Sawafuji swing motor compressor.
About 20 years ago, I helped a friend of a friend with some engine work on a 70's river yacht. It had a Dometic mini-fridge which had dual power capability. There was a 12VDC input and a 120VAC input. I had to do some work on it replacing the wiring, and noticed the compressor had only two wires going to it. The diagram showed the compressor as a "swing motor." The wiring consisted of a two-pole thermostat with one set of contacts controlling the DC power input to the system; and the other side of the thermostat controlling the AC power input. There was a transformer stepping 120V down to 12V and sending 12V AC to the compressor when AC power was connected.
There was a relay which would switch over to the DC system when AC was unavailable. It has a large, wire-wrap constructed circuit with two large transistors and some other oscillator components. This would send a chopped DC signal to the compressor when the DC input was in use. The compressor sounded different with an AC sine wave, versus the chopped DC signal. This is a linear compressor with permanent magnet on the movable part. |

Hello,I have the Europeaan refrigeration condensing unit from Westinghouse ,and wen I want to testing I saw 2 different voltage .in Europe we have 220 volt
,the transformer can use for 110 volt en can use in 115 volt .
She working com both ,but the strange thing is that she not run stand alone by the 115 volt .
