Abstract
A multi cylinder compressor/expansion engine having a centrally mounted drive shaft. A cylinder barrel is mounted on the drive shaft and both the cylinder barrel and the drive shaft rotate about a common axis. There is a plurality of cylinders in the cylinder barrel with pistons disposed in each of the cylinders. Some of the cylinders are compression cylinders and some of the cylinders are expansion cylinders. The compression cylinders discharge a fluid at a first high pressure from the engine. The expansion cylinders receive fluid at a second pressure which provides energy to the engine thereby reducing the energy required for the engine to rotate the drive shaft.
