Abstract
An air-operated engine system usable for driving a vehicle by means of compressed air from a rechargeable storage tank. The engine of the system has cylinders containing driving pistons connected to a crankshaft. Compressed air from the storage tank is supplied at regulated pressure to the cylinders for power strokes by means of intake valves and the air is exhausted from the cylinders at the ends of the power strokes by means of exhaust valves. The intake and exhaust valves are operated by dual lobe cams on a camshaft driven from the crankshaft. The air is compressed by a hydrovane compressor which has a constant flow of air operating under 100 pounds pressure with control valves which will take in 25 pounds per minute up to 200 pounds. The output pressure is controlled by the input pressure.
