摘要: A flow control device typically for protecting a seal (20) in valve, wherein body portion (5) has an orifice (8) allowing fluid flow, and the valve (10) to allow restrict through orifice. The controller (30) between form of at least one annular ring (35), disposed recess (10). defines leak path that is opened closed by pressure differential acting across member. Typically application moves ring(s) end reduces cross sectional area available fluid, thereby diffusing (8).
