Abstract:
A downhole tool for attachment in a production string in a well bore having a casing comprising:a housing having a first fluid passage and a longitudinal axis; a valve coupled to the housing, the valve adapted to substantially block a flow of fluid through the first fluid passage in a first direction; a second fluid passage positioned through the housing in communication with the first fluid passage to permit the flow of fluid to exit through the second fluid passage; a movable cover module coupled to the first fluid passage such that in response to a first electrical signal the movable cover module substantially blocks the flow of fluid to the second fluid passage; and a flow diverting module positioned within the first fluid flow passage such that in response to an increase in fluid pressure the flow diverting module diverts the flow of fluid from the second fluid passage to the first fluid passage.
