Abstract: Systems and methods described herein provide a pilot-operated oscillating valve including a diaphragm. The valve is configured such that when the diaphragm is in a closed position, pressure of a fluid supply opens the valve, and when the diaphragm is in an open position, the pressure of the fluid closes the valve. The oscillating valve may further include an actuator that can cause the valve to be arrested selectively in the open position or the closed position depending on a state of the actuator. The state of the actuator is switchable with a small expenditure of energy, enabling an extended duty cycle for a battery or other power source associated with the actuator. In some implementations, energy from the oscillating movement of the diaphragm may be captured to recharge the battery for the actuator.

Abstract: Apparatuses and methods for urea dosing of an exhaust after treatment system are disclosed. Exemplary apparatuses include a chamber configured to receive pressurized gas at a first inlet, receive urea solution at a second inlet and provide a combined flow of pressurized gas and urea to an outlet, flow passage extending from the first inlet to a seating surface, and a valve member configured to move between an open position in which the valve member is spaced apart from the seating surface and a closed position in which the valve member contacts the seating surface. As the valve member moves from the open position to the closed position, the valve member contacts the seating surface at a first location and wipes an area of the seating surface extending from the first location in a direction toward the flow passage.

Abstract: Apparatus for fluid control device leak detection is disclosed. An example method includes monitoring a value at a purge port of a fluid control device using a sensor, the fluid control device including bellows; comparing the value to a threshold value; and determining, via a processor, that the value is outside of the threshold value, the value being outside of the threshold value indicative of a leak in the bellows.

Abstract: A fluid pressure regulating unit, comprises a fluid inlet port, a fluid outlet port, a valve comprising a movable valve part, wherein the movable part comprises at least one fluid pressure balancing means and wherein the at least one pressure balancing means comprises a tapered surface, and a main valve biasing means. The main valve biasing means biases said valve in the direction of an open position. An auxiliary valve biasing means is provided, biasing the valve in the direction of a closed position. Wherein essentially every surface part, being in fluid connection to the fluid inlet port and having a surface normal at least partially in parallel to the moving direction of the moving part of the valve, is balance by a balancing surface part.

Abstract: A valve assembly for high pressure applications includes a pre-charge chamber in fluid communication with a first bellows, at least one inlet for pressurized gas to enter the assembly, a system poppet and an outlet for releasing pressurized gas into a desired environment. The pre-charge chamber and first bellows are filled with pre-charge gas to a threshold pressure. Pressurized gas can flow through access channels into a second bellows, which expands to move a valve shaft connected to the poppet assembly to open the poppet and allow the release of gas. The expansion of the second bellows pushes incompressible fluid disposed between the two bellows against the first bellows, thus contracting the first bellows. The gas within each bellows maintains an internal pressure equal to the pressure exerted upon each bellows by the incompressible fluid, so as to minimize differential pressure across the bellows in the extended position.
