A fluidic valve may include an inlet, a control port, an additional control port, an outlet, a fluid channel configured to convey fluid from the inlet to the outlet, and a piston that includes (1) a restricting gate transmission element configured to block, when the piston is in a first position, the fluid channel and unblock, when the piston is in a second position, the fluid channel, (2) a controlling gate transmission element configured to interface with a control pressure from the control port that forces the piston towards the first position when applied to the controlling gate transmission element, and (3) an additional controlling gate transmission element configured to interface with an additional control pressure from the additional control port that forces the piston towards the second position when applied to the additional controlling gate transmission element. Various other related devices, systems, and methods are also disclosed.

An autonomous flow control device with pilot amplification includes a primary valve responsive to changes in fluid composition, and a pilot valve responsive to and more sensitive to changes in fluid composition than the primary valve and configured to aid change in position of the primary valve in the event of a change in fluid composition

A distributed fuel module includes a fuel pressure vessel with a gas port and a fuel port, a hydraulic circuit breaker connected to the fuel port, and a gaseous circuit breaker. The gaseous circuit breaker is connected to the gas port, is fluidly coupled to the hydraulic circuit breaker through the fuel pressure vessel, and is cooperatively associated with the gaseous circuit breaker to isolate the fuel pressure vessel from a compressed gas header and a fuel header according to pressure differential within the hydraulic circuit breaker and pressure differential within the gaseous circuit breaker. Power modules and methods of controlling fuel flow in fuel modules are also described.

A pneumatic valve for attachment to a source of high pressure gas comprises a valve body which comprises a gas inlet and a gas outlet. A rupturable membrane extends across the gas inlet. A membrane support element is slidably supported in the valve body for movement between an extended position and a retracted position, the membrane support element having a lower end engageable, in the extended position, with the rupturable membrane to support the rupturable membrane against rupture. The valve body further comprises a bore through which the membrane support element extends and one or more gas supply passages bypassing the bore for providing a gas flow path from the gas inlet to the gas outlet. The membrane support element is configured to be movable from the extended position to the retracted position to permit the rupturable membrane to rupture under the pressure of the high pressure gas.

Disclosed are downforce feedback systems for active aerodynamic devices, methods for making/using such systems, and vehicles equipped with a closed-loop downforce feedback system to govern operation of the vehicle's active aero device(s). A feedback control system for operating an active aerodynamic device of a motor vehicle includes one or more pressure sensors for detecting fluid pressures in one or more pneumatic or hydraulic actuators for moving the active aero device. A vehicle controller receives fluid pressure signals from these sensor(s), and calculates an actual downforce value from these signal(s). The controller retrieves a calibrated downforce value from mapped vehicle downforce data stored in memory, and determines if the actual downforce value differs from the calibrated value. If so, the controller determines a target position for a target downforce value for a current vehicle operating condition, and commands the actuator(s) to move the active aero device to the target position.

A control system for actuating a drill pipe rack is provided. The drill pipe rack moves between a first position and a second position. The control system includes a first actuator to actuate a top end of the drill pipe rack and a second actuator to actuate a bottom end of the drill pipe rack. The control system includes a pump to supply pressurized fluid to the first actuator and the second actuator. The control system further includes at least one volumetric flow divider in fluid communication with the pump. The volumetric flow divider is configured to supply equal volumetric quantity of the pressurized fluid to the first actuator and the second actuator, and subsequently move the drill pipe rack between the first position and the second position.
