  • Flow control mechanism for downhole tool
    Patent number: 9528356
    Abstract: Flow control mechanism (100) for a downhole tool includes a housing (102), an inner liner (104), and a rotatable sleeve (106). The inner liner (104) is provided in and remains stationary relative the housing (102). The rotatable sleeve (106) can be arranged to rotate about the inner liner (104) to provide a closed configuration (900), a first open configuration (1400), and a second open configuration (1900). The closed configuration (900) can enable through-flow of fluid through the flow control mechanism (100) to a distal tool (50). The first open configuration (1400) can enable partial through-flow of fluid through the flow control mechanism (100) to the distal tool (50) and partial through-flow of fluid in a substantially radial direction. The second open configuration (1900) can prevent through-flow of fluid through the flow control mechanism to the distal tool (50) and to enable through-flow of fluid in a substantially radial direction.
