The Swing Compressor

The Swing Compressor is an electro-dynamic reciprocating device that connects directly to the piston of the compressor. It is a true reciprocating compressor with only one moving part. The piston is connected to an electro dynamic device which is powered by the use of magnetic fields. There is no need for bearings, cranks or con-rods, with this technology. Less moving parts literally means less chance of failure. Because the Swing compressor has only one moving part there is a very low friction loss.  i.e. This is a highly efficient compressor.

The compressor has no high start up current draw because when it starts up it can simply move down just a fraction then return. Then it slowly increases the distance the piston travels each stroke until it reaches a full stroke. The Sawafuji Swing Motor does not need to perform a full stroke on start up unlike many rotary type compressors that must perform a complete cycle, thereby needing much more current to start.

The Sawafuji Swing Motor is located inside the compressor casing with pins locating in rubber bushes then suspended in between shock absorbent springs. It operates at 30 degrees angles and on rough corrugated dirt roads without losing efficiency.  See Diagrams to the right.
