Abstract:
A fluid flow control device (10) has a stack of annular discs (15) defining a central passageway (14) and a plug (16) reciprocable in the passageway for controlling fluid flow. Adjacent discs (15) in the stack have at least one fluid passageway (21A) formed in a major face (22A) of one disc closed by the abutting major face of the adjacent disc. The fluid passageway (21A) extends in a clockwise direction and has a linear inlet portion (23A) and a curved outlet portion (24A). The inlet portion (23A) is of constant cross-sectional area and the outlet portion (24A) is of increasing cross-sectional are in the direction of fluid flow.
