Noise suppressor for firearms
View Patent ↗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.
1. A firearms noise suppressor for firearms that have a barrel with a distal end wherein the noise suppressor is attachable to the distal end of the barrel, the noise suppressor comprising:
a housing having an exterior surface and an interior surface, an interior chamber defined by the interior surface of the housing, a proximate end that is attachable to the distal end of a firearm barrel, and a distal end, the housing being tapered at each of the distal and proximate ends;
a barrel disposed within the interior chamber and having an exterior surface, and further having a length extending from the proximate end to the distal end of the housing, the barrel further having a plurality of perforations spaced apart along the length to vent exhaust gases, the perforations being oriented so that the vent direction of the exhaust gases varies from one perforation to the next;
a plurality of perforated baffles spaced along the exterior surface of the barrel, each one of the plurality of perforated baffles extending from the exterior surface of the barrel to the interior surface of the housing and being sized to fit to the tapered shape of the housing; and
a plurality of receiving grooves spaced along the interior surface of the housing to receive the baffles,
whereby the tapered shape of the housing provides space for gas expansion and thereby enhances the suppression of noise from expanding gases.
2. The firearms noise suppressor of claim 1 , further comprising a valve-operated fluid discharge port to discharge fluid after submersion of the suppressor in a fluid.
3. The firearms noise suppressor of claim 1 , wherein the plurality of barrel perforations comprise a series of vents wherein each vent of the series of vents is oriented to vent in a different direction from a proximate vent.
4. The firearms noise suppressor of claim 1 , further comprising a pair of joined housing moieties.
5. The firearms noise suppressor of claim 4 , further comprising a gasket between the joined housing moieties.
6. A firearms noise suppressor for firearms that have a barrel with a distal end wherein the noise suppressor is attachable to the distal end of the barrel, the noise suppressor comprising:
a housing having an exterior surface and an interior surface, an interior chamber defined by the interior surface of the housing, a proximate end that is attachable to the distal end of a firearm barrel, and a distal end, the housing being tapered at each of the distal and proximate ends;
a barrel disposed within the interior chamber and having an exterior surface, and further having a length extending from the proximate end to the distal end of the housing, the barrel further having a plurality of perforations spaced apart along the length to vent exhaust gases, the perforations being oriented so that the vent direction of the exhaust gases varies from one perforation to the next;
a plurality of perforated baffles spaced along the exterior surface of the barrel, each one of the plurality of perforated baffles extending from the exterior surface of the barrel to the interior surface of the housing and being sized to fit to the tapered shape of the housing;
a plurality of receiving grooves spaced along the interior surface of the housing to receive the baffles; and
a valve-operated fluid discharge port to discharge fluid after submersion of the suppressor in a fluid,
whereby the tapered shape of the housing provides space for gas expansion and thereby enhances the suppression of noise from expanding gases.
