Title:
METHOD AND DEVICE FOR FLOW CONTROL
Document Type and Number:
WIPO Patent Application WO/2017/098032
Kind Code:
A3
Abstract:
A flow control device, a system and a method are disclosed. The flow control device comprises a displaceable means (101) having a direction of displacement and being displaceable between a first position and a second position. The flow control device further comprises a body (110) comprising a first cavity (102) in fluid contact with a first side of the displaceable means (102) forming a first volume. The first cavity further comprising a first inlet (103), a primary outlet (104) with a primary flow resistance and arranged essentially parallel with the displacement direction, wherein the primary outlet comprises an inlet opening (105) facing the displaceable means at a first distance (106) from the displaceable means in the direction of displacement, a secondary outlet (107) with a secondary flow resistance, wherein the displaceable means is displaceable between a first position and a second position. In the first position, a first fluid path (108) between the first inlet (103) and the primary outlet (104) is provided, and a second flow path (109) between the inlet (103) and the secondary outlet (107) is provided; In the second position, the displaceable means is displaced at least the first distance and close the inlet opening (105) of the primary outlet, whereby the inlet opening (105) is blocked, and the second fluid path (109) between the first inlet (103) and the secondary outlet (107) is maintained.
