Abstract: A subsurface safety valve actuation system in well tubing comprising a safety valve, piston assembly, motor, pump, spring, reservoir, first valve, and second valve configured to provide pressure in a chamber of the piston assembly that drives the safety valve to an open position, retain pressure in the chamber that retains the safety valve in the open position, release pressure in the chamber via a first hydraulic release path and/or a second hydraulic release path between the chamber and the reservoir that extends through the first valve and second valve, respectively, and the first and second hydraulic release paths being independent from each other, whereby pressure in the chamber that retains the safety valve in the open position may be released via the first or second hydraulic release path when there is a fault in the other of the first or second release path.

Abstract: A turbine active combustion instability control system comprising a primary passage to a combustor of a turbine; a combustor pressure sensor configured to measure dynamic pressure within the combustor; a pilot valve metering fuel flow through a pilot passage to the combustor and comprising a valve seat defining a throat in the pilot passage and a valve plug movable to control fuel flow through the throat, the pilot valve having an inlet passage with a contoured surface to accelerate gas flow through the throat to at least Mach 1; a dynamic linear motor actuator connected to the valve plug and configured to actuate the valve plug at a high frequency; and a controller configured to provide a control signal to the actuator as a function of input from the combustor pressure sensor.

Abstract: An electro-hydraulic piston pump system comprising an electric motor (16), first and second hydraulic piston pumps (30,60), a first hydraulic actuator (90) having a first port (93) connected directly to a first port (48) of the first pump and a second port (94) connected directly to a second port (49) of the first pump, a second hydraulic actuator (100) having a third port (103) connected directly to a third port (78) of the second pump and a fourth port (104) connected directly to a fourth port (79) of the second piston pump, wherein an external force applied to the first hydraulic actuator (90) that provides a negative pressure differential to the first pump applies an assistive torque to a common motor shaft (18) driving both the first pump (30) and the second pump (60), and an external force applied to the first and second actuators (90,100) that provides a summed negative pressure differential to the first and second pumps (30,60) recharges a power supply for the motor (16).
