Abstract
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.
