摘要： A gas lift valve has a flow restrictor, a valve part on one side of the flow restrictor, a flow deflector and a tubular member on another side of the flow restrictor, and a flapper valve on the side of the flow restrictor where the tubular member is located, the flapper valve being adjacent to the tubular member. When fluid flows into the gas lift valve at sufficient pressure, the valve part opens, the fluid flows through the flow restrictor and acts on the flow diverter thereby moving the tubular member and opening the flapper valve. The tubular member extends though the opening the flapper valve covered.

摘要： An actuating method includes applying an input pressure to a first side of a tool operator and to a second side of the tool operator and moving the tool operator from a first position to a second position in response to depleting the input pressure applied to the second side. A state of a tool element can be changed in response to moving the tool operator from the first position to the second position. The input pressure may be depleted from the second side of the tool operator by transferring hydraulic fluid to a confined diameter container disposed in an annular region of the actuating device or to the first side of the tool operator.
