Abstract

A massive piston, which might be called a 'ram', except that it does not strike anything during operation, reciprocates with bouncing action up and down within a cylinder. An annular pressurized gas storage chamber encircles the piston and travels up and down with it. Pressurized gas is continuously supplied into this movable chamber to be temporarily stored therein. As the piston descends toward the lower end of the cylinder, pressurized gas from this travelling chamber is automatically suddenly allowed to bypass the lower portion of the piston, thereby injecting the pressurized gas into a bounce chamber between the descending piston and a bottom assembly. When this pressurized gas rushes through the bypass, it forces an exhaust valve closed. The bypass includes two vertically spaced sets of gas feed ports communicating into the cylinder, and as the piston continues descending closer to the bottom assembly, the injected pressurized gas is suddenly trapped becoming further compressed as a cushion with great pressure multiplication below the descending piston, thereby producing a powerful driving thrust while bouncing the piston upwardly in a powerful bouncing action. As the piston ascends, additional pressurized gas automatically bypasses from the storage chamber into the cylinder, and its expansion aids in propelling the piston up relatively high. The ascending piston allows gas expansion, until pressure has dropped approximately to atmospheric, thereby allowing the exhaust valve to open. When this valve opens, the piston is near the top of its stroke, and the cycle repeats.
