초록 ▼

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.

A flow control device for providing a substantially constant rate of fluid flow under varying pressure through a passageway in a housing, said device comprising a resilient member having spaced-apart upstream and downstream sides and dimensionally adapted to enable the member to be removably received within the housing with said downstream side having an intermediate region surrounded by a substantially flat peripheral surface facing in the downstream direction that is adapted to engage a seat in the passageway directly while assuring that the intermediate region remains in fluid communication with the downstream side of the passageway, said member having at least one flow control orifice extending therethrough between the upstream side and the downstream side within the intermediate region, said member having a plurality of bypass channels extending therethrough between the upstream side and downstream peripheral surface in the direction of fluid flow through the passageway in the housing, said plurality of bypass channels being in a spaced-apart array about the orifice, said orifice adapted to constrict and relax to maintain a substantially constant rate of fluid flow therethrough in response to compression and relaxation of the member against the seat in response to respective increases and decreases in the fluid pressure differential across the member, and said member having reduced tendency to flutter and improved resistance to fatigue failure arising from the repeated relaxation and compression thereof under varying fluid pressure differentials across the member as a result of said channels being positioned so that at least a portion of each intersects the intermediate region, the peripheral surface, and an intersection between the intermediate region and the peripheral surface to the extent necessary to enable compression and relaxation of the intermediate region adjacent the peripheral surface to control the flow of the fluid through the channels in response to respective increases and decreases in the fluid pressure differential across the member.
