Compressed Air Engine
This is a six cylinder compressed air engine built using my pneumatic cylinders and rotary valves. I have not connected the output ports of the rotary valves to the ports of the cylinders using tubing (they would need to be connected).
In a gas powered engine, each cylinder is active or live only for half the cycle (down stroke). In this design each cylinder is active for the full cycle. Engine can be connected to a motor to generate power. Alternately, if the motor is powered, you should be able to use the engine as compressor.
One could potentially use this as a compressor at night using power off the grid when electricity rates are lower, and then as a generator during the day. Simpler two and four cylinder engines can also be constructed quite easily.
If you are looking for a cheap compressor to power the model, Harbor Freight Supply has one for $8 and it includes a pressure gauge!
