ABSTRACT:
Disclosed is a resilient fatigue resistant flow control device (140) for maintaining a substantially constant rate of fluid flow through a passageway (64) under varying fluid pressure differentials across the device. The device comprises at least one metering orifice (72) extending between the upstream and downstream sides within a defined region (R) that is circumscribed on the downstream side by a peripheral surface (78) that is adapted to rest directly against a seat (68) in the passageway. A plurality of spaced-apart bypass channels (84) extend through the device between the upstream side and the downstream peripheral surface that are positioned so that at least a portion of each channel intersects region (R) adjacent the peripheral surface so that the compression and expansion of region R adjacent the peripheral surface is able to control the amount of fluid flowing through the channels.
