Zusammenfassung:	A control valve trim assembly has a body having an annular first section and a longitudinally adjacent annular second section and defines an inner surface and an outer surface. A plurality of first openings are formed in the inner surface of the first section of the body and a plurality of second openings are formed in the outer surface of the first section of the body. Each of the first openings is in fluid communication with a corresponding second opening via a fluid passage formed through the body, which passes through the first section and the second section and each of the fluid passages has at least one radially extending portion and at least one longitudinally extending portion.
