Claim 3:
4. A director plate retainer of a fluid injector, said director plate retainer being configured to retain a director plate of said fluid injector which shapes and atomizes fluid exiting said fluid injector, said director plate retainer comprising:
a director plate retainer outer wall which is annular in shape and which extends from an outer wall first end to an outer wall second end and which is centered about an axis;
a director plate retainer lateral wall which is annular in shape and which extends toward said axis from a radially outer extent, which is proximal to said director plate retainer outer wall, to a radially inner extent, which is distal from said director plate retainer outer wall; and
a director plate retainer inner wall which is annular in shape and which extends from an inner wall first end, which is proximal to said director plate retainer lateral wall, to an inner wall second end, which is distal from said director plate retainer lateral wall, said director plate retainer inner wall extending along said axis in a direction that is opposite from said director plate retainer outer wall such that said director plate retainer outer wall extends upwardly from said director plate retainer lateral wall, and said director plate retainer inner wall extends downwardly from said director plate retainer lateral wall;
wherein said director plate retainer lateral wall is inclined relative to said axis such that said radially inner extent is closer to said outer wall first end than said radially outer extent is to said outer wall first end so that an intersection of the director plate retainer lateral wall and the director plate retainer inner wall makes first contact with the director plate when the director plate retainer is installed in the fluid injector.
