Abstract (en)

[origin: WO2005045180A1] An actuating mechanism (111) comprising an inner member (113) and an outer member (115) axially slidable relative to each other, the inner and outer members (113, 115) cooperating to define an internal passage (117) for the flow of a fluid therethrough. The inner member (113) being configured such that upon a predetermined change in pressure between a first region (119) and a second region (120) the actuating mechanism (111) is caused to move between a first condition and a second condition.
