摘要: Actuation mechanisms for downhole assemblies in earth-boring applications may comprise a housing comprising an internal bore defining flow path through the housing. An actuation member be supported within A movable sleeve located and between first position second responsive to changes rate of fluid flowing path. The biased toward position. initial, pre-actuation when is initially subsequent, released from mechanism returned
