摘要： A downhole valve apparatus including a force transmitter configured to move in an axial direction and a valve actuator configured to move in an axial direction. The valve actuator is independently movable relative to the force transmitter and physically isolated from the force transmitter. A first magnetic assembly is disposed at the force transmitter. A second magnetic assembly is disposed at the valve actuator. The first and second magnetic assemblies are configured to repel one another and cause the force transmitter to move the valve actuator when the force transmitter is moved toward the valve actuator.

摘要： A tubing pressure insensitive actuator system includes a housing having a bore therein. A force transmitter is sealingly moveable within the bore, the force transmitter defining with the bore two fluid chambers. One of the fluid chambers is at each longitudinal end of the force transmitter. At least two seals are sealingly positioned between the housing and the force transmitter, with one of the seals isolating one end of the force transmitter from tubing pressure and another of the seals isolating another end of the force transmitter from tubing pressure. A method is also included.

摘要： Piston bore distortions in a sub-surface safety valve are reduced or eliminated when valve body is subjected to high working pressures. In one embodiment, a piston is disposed in a sleeve that is disposed in a piston bore. The bore can distort but the sleeve within will not distort to the point of losing sealing pressure around the piston. In another approach additional bore or bores are provided adjacent the piston bore to make the pin end of the connection for the valve housing more uniform in the region of the piston bore so that pressure loading does not result in sufficient distortion of the piston bore to lose the piston sealing relation in its bore.
