Claim 18:
19. A system, comprising:
a piston assembly, comprising:
a crown portion, comprising:
a crown;
an outer wall coupled to the crown, wherein the outer wall extends circumferentially about a central axis of the piston assembly;
a first inner wall disposed inside of the outer wall, wherein the first inner wall extends circumferentially about the central axis; and
a first fluid chamber disposed radially between the outer wall and the first inner wall, wherein the first fluid chamber extends circumferentially about the central axis, an opening extends into the first fluid chamber in an axial inward direction, and the opening extends circumferentially about the central axis; and

an angled wall insert disposed in the opening in the crown portion, wherein the angled wall insert extends circumferentially about the central axis, and the first fluid chamber is disposed axially between the crown and the angled wall insert;
wherein the angled wall insert comprises an angled annular plate, wherein the angled annular plate is oriented at an acute angle relative to the central axis; wherein a plate thickness of the angled annular plate is less than an outer wall thickness of the outer wall along the first fluid chamber, a crown thickness of the crown along the first fluid chamber, and an inner wall thickness of the first inner wall along the first fluid chamber.
