Patent ID: 7556092

Claim:
A method of controlling the flow of fluidic materials within a tubular housing that defines an inlet passage and one or more outlet passages, comprising: injecting fluidic materials into the inlet passage; blocking the inlet passage; and opening the outlet passages; conveying the injected fluidic materials radially out of the inlet passages into a plurality of circumferentially spaced apart longitudinal passages defined in the tubular housing and into an annular chamber defined in the tubular housing that surrounds the inlet passage; and opening the outlet passages to permit fluidic materials within the inlet passage and the annular chamber to be conveyed out of the housing; increasing the pressure of fluid materials outside of the housing; and displacing an expansion cone when the pressure of fluidic materials outside of the housing exceeds a predetermined level; wherein opening the outlet passages comprises detecting the operating pressure of the injected fluidic materials; and if the detected operating pressure of the injected fluidic materials exceeds a predetermined amount, then opening the outlet passages.
