<p>This disclosure describes a flow control device comprising: a body comprising a body wall that defines a chamber, the body wall comprising an inlet in fluid communication with the chamber, a work outlet comprising a work outlet flow area in fluid communication with the chamber, and a bleed outlet comprising an unoccluded bleed flow area in fluid communication with the chamber. The flow control device comprises a flow control member adapted to selectively occlude the bleed outlet wherein, in a second position, the flow control member at least partially occludes the bleed outlet to create a second bleed flow area and, in a first position, the flow control member occludes the bleed outlet to a smaller degree than when in the second position to create a first bleed flow area that is greater than the second bleed flow area.</p> |
