Multiple flange crush washer
First Claim
1. A crush washer for a firearm, the crush washer comprising a ring of material about a center axis having an inner surface towards the center axis and an outer surface away from the center axis, and at least one groove in the inner surface or outer surface forming:
- a first flange having an inner surface and an outer surface with a thickness therebetween;
a second flange having an inner surface and an outer surface with a thickness therebetween; and
a bridge connecting the first flange and the second flange, the bridge having an inner surface and an outer surface with a thickness therebetween;
wherein in an undeformed state, the inner surface of the first flange is adjacent to, but spaced apart from, the inner surface of the second flange;
wherein in a deformed state, the inner surface of the first flange is closer to the inner surface of the second flange compared to the undeformed state; and
wherein the thickness of the bridge is less than the thickness of the first flange and less than the thickness of the second flange.

Abstract
One aspect of the present disclosure is directed to a crush washer for a firearm that comprises a ring of material about a center axis having an inner surface towards the center axis and an outer surface away from the center axis, and at least one groove in the inner surface or outer surface. The groove forms: a first flange having an inner surface and an outer surface with a thickness therebetween; a second flange having an inner surface and an outer surface with a thickness therebetween; and a bridge connecting the first flange and the second flange, the bridge having an inner surface and an outer surface with a thickness therebetween. In an undeformed state, the inner surface of the first flange is adjacent to, but spaced apart from, the inner surface of the second flange. In a deformed state, the inner surface of the first flange is closer to the inner surface of the second flange compared to the undeformed state. The thickness of the bridge is less than the thickness of the first flange and less than the thickness of the second flange.

8. A firearm comprising:
-
a barrel having a muzzle end and a rear end; a muzzle treatment attached to the muzzle end of the barrel; a crush washer disposed around the barrel and adjacent to the muzzle treatment, wherein the crush washer is adapted to deform under pressure and provide a jamming force between the muzzle treatment and the barrel, and wherein the crush washer comprises a groove forming; a first flange having an inner surface and an outer surface with a thickness therebetween; a second flange having an inner surface and an outer surface with a thickness therebetween; and a bridge connecting the first flange and the second flange, the bridge having an inner surface and an outer surface with a thickness therebetween; wherein the thickness of the bridge is less than the thickness of the first flange and less than the thickness of the second flange. - View Dependent Claims (9, 10, 11, 12, 13, 14)
