Patent ID: 7011192

Claim:
A powerful gas cylinder and shock absorber and accelerator device, comprising: (i) a gas cylinder portion comprising: a cylinder body including a rear-end head having a rear port and a front-end head having a front port and including a rod, the front port and rear port for inlet and outlet of a cylinder gas, a cylinder piston connected to the rod, the cylinder piston and rod movable within the cylinder body, there being a clearance between the piston and the inner wall, cylinder sealing structures that seal the cylinder piston against the cylinder body and that seal the rod against the front-end head, (ii) a shock absorber and accelerator portion, comprising: an inner chamber containing a gas, an outer storage chamber for containing compressed gas, an inner wall defining a boundary between the outer storage chamber and the inner chamber, the inner wall having a first aperture defined therein connected to a port for inlet and outlet of the cylinder gas and having a second aperture defined therein connected to the outer storage chamber, the cylinder piston, upon the exertion of a force against the rod, moving through a retraction stroke, sealing the second aperture and compressing gas in the inner chamber and driving the gas through the first aperture to the outer storage chamber, a sealing structure that seals the clearance so that when the piston moves through a portion of the inner chamber during an intermediate portion of the retraction stroke a first sealing structure seals the first aperture and a second sealing structure seals the second aperture, the first and second apertures staying sealed during a remainder of the retraction stroke, a counterforce-generating member for moving the piston an initial distance to initiate an extension stroke, said initial distance being sufficient to release the sealing of the aperture, the cylinder piston, upon the release of the sealing of the first aperture, being accelerated by compressed gas that rushes in from the outer storage chamber to the inner chamber, and upon the release of the sealing of the second aperture being further moved for a remainder of the extension stroke, a venting pathway from the inner chamber to an area external to the device for venting gas in the inner chamber at approximately the completion of the retraction stroke.
