Cleaning apparatus for sealed firearm suppressor
View Patent ↗A cleaning apparatus for internally cleaning firearm suppressors is disclosed. The cleaning apparatus includes a reservoir configured to contain a cleaning fluid, a pump in fluid communication with the reservoir, and a spray tube coupled to the pump and dimensioned to be insertable within a firearm suppressor. The spray tube includes a sealed distal end and a plurality of apertures arranged to discharge pressurized fluid radially outward, with alternating patterns along opposing sides. A fluid return system collects the discharged fluid and recirculates it to the reservoir via a fluid return connector positioned above the reservoir floor to minimize particulate intake. The apparatus may include a cylindrical reservoir supported by a base housing, compression fittings, a removable lid, electrical controls, and an accessible drain assembly. A support structure holds the suppressor in a vertical orientation with drainage clearance. The system enables efficient, contained, and repeatable internal cleaning of firearm suppressors.
1 . A cleaning apparatus for internally cleaning firearm suppressors, comprising:
a reservoir configured to contain a cleaning fluid;
a pump in fluid communication with the reservoir and configured to pressurize the cleaning fluid;
a spray tube having a proximal end and a distal end, the proximal end being coupled to the pump, the spray tube including a plurality of apertures distributed along a length thereof and configured to discharge the pressurized cleaning fluid radially outward, wherein the spray tube is dimensioned to be insertable within a bore of a firearm suppressor; and
a fluid return system configured to collect the cleaning fluid discharged from the firearm suppressor and return the collected cleaning fluid to the reservoir for recirculation through the pump.
2 . The cleaning apparatus of claim 1 , wherein the spray tube has an outer diameter between about 3 mm and about 6 mm.
3 . The cleaning apparatus of claim 1 , wherein the apertures are arranged in an alternating pattern along opposing sides of the spray tube.
4 . The cleaning apparatus of claim 1 , wherein the distal end of the spray tube is sealed to direct the pressurized cleaning fluid through the apertures.
5 . The cleaning apparatus of claim 1 , wherein the fluid return system includes a suction strainer positioned in the reservoir.
6 . The cleaning apparatus of claim 5 , wherein the suction strainer is configured to filter debris from the cleaning fluid returning to the pump.
7 . The cleaning apparatus of claim 1 , further comprising a base housing supporting the reservoir, wherein the pump is contained within the base housing.
8 . The cleaning apparatus of claim 7 , further comprising a drain assembly connected to the reservoir and accessible from an exterior of the base housing.
9 . The cleaning apparatus of claim 1 , wherein the reservoir includes a removable lid configured to provide access to an interior of the reservoir.
10 . A cleaning apparatus for internally cleaning firearm suppressors, comprising:
a reservoir having a bottom wall with at least two fluid connection ports;
a pump positioned below the reservoir;
a spray tube extending upward from the bottom wall and having a sealed distal end and a plurality of apertures, the spray tube being dimensioned to fit within standard suppressor bore diameters;
a pressurized fluid supply line connecting the pump to the spray tube through a first fluid connection port;
a fluid return system connecting the pump to a second fluid connection port and including a suction strainer;
electrical controls operatively connected to the pump; and
a support structure configured to position a firearm suppressor over the spray tube such that the suppressor is maintained in a vertical orientation with clearance from the bottom wall.
11 . The cleaning apparatus of claim 10 , wherein the spray tube has an outer diameter of approximately 4 mm.
12 . The cleaning apparatus of claim 10 , wherein the apertures are positioned along a middle portion of the length of the spray tube, with the end portions being free of apertures.
13 . The cleaning apparatus of claim 10 , wherein the suction strainer is configured to prevent intake of settled particulates.
14 . The cleaning apparatus of claim 10 , further comprising a drain assembly including a third fluid connection port in the bottom wall and an externally accessible drain assembly.
15 . The cleaning apparatus of claim 10 , wherein the reservoir is transparent to allow visual monitoring of cleaning operations.
16 . The cleaning apparatus of claim 10 , wherein the support structure includes spacer elements configured to elevate the suppressor above the bottom wall while allowing cleaning fluid to drain from both ends of the suppressor.
17 . A cleaning apparatus for internally cleaning firearm suppressors, comprising:
a reservoir having a cylindrical configuration;
a base housing supporting the reservoir and containing a pump;
a spray tube having an outer diameter sized to fit within standard firearm suppressor bores and including alternating apertures spaced along a central section of the spray tube, wherein the alternating apertures are arranged such that adjacent apertures are positioned on opposite sides of the spray tube;
compression fittings securing the spray tube to the base housing and connecting the spray tube to a discharge output of the pump;
a fluid return system including a suction strainer and connected to an intake of the pump, wherein the suction strainer is configured to avoid intake of settled particulates;
a drain assembly including a bottom drain port in fluid communication with the reservoir and an external quarter-turn valve;
electrical controls integrated into the base housing and operatively connected to the pump; and
a support structure configured to center a firearm suppressor over the spray tube and maintain the suppressor in vertical alignment with drainage clearance from both ends of the suppressor.
18 . The cleaning apparatus of claim 17 , wherein the spray tube includes a sealed distal end configured to direct the pressurized cleaning fluid through the alternating apertures.
19 . The cleaning apparatus of claim 17 , wherein the reservoir includes a removable lid configured to provide sealed access to an interior of the reservoir during cleaning operations, and wherein the electrical controls include at least one power switch accessible from an exterior surface of the base housing, and wherein the support structure includes spacer elements configured to elevate the firearm suppressor above the floor of the reservoir.
