Abstract
Techniques and equipment to facilitate controlling flow of a fluid along a flow passage. A flow control assembly is placed along a flow passage, and a bypass is routed past the flow control assembly. Flow along the bypass is controlled by a flow bypass mechanism which may be operated via pressure increase within the flow control assembly. A shear device restricts the opening of the bypass, and a dampening device acts to limit the shear device to exposure of forces from the pressure increase.
