20100000398 | ASYMMETRIC FIREARM SILENCER WITH COAXIAL ELEMENTS - The present invention relates to a silencer for reducing muzzle blast and noise of firearms or similar devices. The present silencer has a hollow cylindrical or other shape casing comprising front and rear end caps and an opening aligned along a longitudinal axis defining a passage for a projectile and propellant gases to emerge from the muzzle opening. A plurality of serially placed baffles of symmetrical or slanted orientation and intervening coaxial spacers are positioned within the casing and define a multitude of chambers among the baffles, spacers, and outer housing. The baffles shear propellant gases away from the projectile path and through openings or ports into additional chambers formed between the spacers and outer housing. The arrangement of baffles and spacers provides flow-impeding paths, dispersion, and controlled expansion of gases and lowers gas temperature to reduce audible noise and observable signature of the muzzle blast. | 01-07-2010 |

20100180759 | ENERGY SUPPRESSORS - A suppressor for a firearm includes a first gas expansion section of relatively large size sufficient to reduce the temperature and pressure of the gas expelled from a muzzle during discharge of the firearm to a level that avoids rapid degrading of structural members such as baffles in the suppressor that are downstream of the muzzle. The gas is channeled through multiple paths to distribute its energy more equally. Preferably, the suppressor is formed with a lightweight, thermally-conductive composite portion. The composite portion provides lightweight, bursting strength with good thermal conductivity and little contribution to vibrational instability of the muzzle to which it is attached. The composite portion may be of a carbon fiber, silicon, boron, or metallic base. In one embodiment, a first expansion chamber is in communication with the muzzle and with a second expansion chamber and in another embodiment, the first expansion chamber communicates with the muzzle and with the second expansion chamber The composite portions of the suppressor provide good bursting strength and heat conductivity with light weight. In some embodiments, a series of baffles creates turbulence in the gas, slowing its motion and distributing the energy more evenly over space. | 07-22-2010 |

20110107900 | CONTROLLED-UNAIDED SURGE AND PURGE SUPPRESSORS FOR FIREARM MUZZLES - A Controlled Unaided Surge and Purge (CUSPS) suppressor for firearms uses the blast and plume characteristics inherent to the ballistic discharge process to develop a new two-step controlled surge and purge system centered around advanced mixer-ejector concepts. The blast surge noise is reduced by controlling the flow expansion, and the flash effects are reduced by controlling inflow and outflow gas purges. In the preferred embodiment, suppressor vent holes are convergently contoured to better reduce the blast surge. Preferably a two-stage supersonic mixer/ejector system, in combination with adjacent vent holes in the suppressor housing and a divergent entrance nozzle, is used to control or eliminate the external Mach disk, while rapidly mixing and diluting the propellant with purged gases. A diffuser downstream of the mixer/ejector system further increases ejector performance and pumping. The pumped gases are used to self-clean and cool the CUSPS suppressor. | 05-12-2011 |

20150135935 | Rifle Noise Suppressor - My invention is a rifle noise suppressor comprised of a cylindrical chamber which contains a nested set of baffles concentrically and longitudinally arrayed through the chamber. One end of the chamber is threaded and threads are cut into the barrel of a rifle to permit the noise suppressor to be screwed into place. The chief advantage of the concentrically arrayed baffles is a shorter chamber, approximately one-half the length of a typical noise and smoke suppression device, yet able to achieve equal noise and smoke suppression by causing the escaping gases following the explosion of the bullet being fired to travel farther within the suppressor chamber. | 05-21-2015 |
20150308772 | Noise Suppressor For Firearms - A suppressor to diminish the volume of noise from firing a firearm provides a suppressor body shape with tapered ends. The shape of the suppressor forms a partial wave-form to accommodate the wave-forms of the ignition gasses as they expand inside the chamber. Providing a chamber with a partial wave-form shaped interior space facilitates rapid dissipation of the expansion energy of the ignition gasses to quickly quell noise produced by such expansion. Perforated baffles housed in the interior chamber of the suppressor disrupt the fluid flow as the ignition gasses proceed through the chamber, which further dissipates the energy of the gasses. A fluid discharge port evacuates fluid from the primary chamber of the suppressor. | 10-29-2015 |
