A centrifugal debris trap includes a cylindrical chamber bound by an inner
surface of a continuous wall radially disposed about a center axis at a
first inner diameter, and having a first wall end and a second wall end;
and a plurality of grooves between the first and second wall ends,
extending radially outward from the inner surface into a portion of the
continuous wall, and each having a groove outer diameter that is greater
than the first inner diameter. The cylindrical chamber is sealed at the
first wall end by a back plate attached about a circumference of the
first wall ends, and is open at the second wall end through a ring
attached thereto about a circumference of the second wall end. The ring
has a ring opening radially disposed about the center axis, and a second
inner diameter less than the first inner diameter.
