Abstract: A flexure includes a flexure body with an inner ring defining a main axis and an outer ring extending about the inner ring that is outboard of the inner ring with respect to the main axis. One or more flexure members having respective lengths that are greater than a radial offset distance defined between the inner ring and the outer ring connects the inner ring to the outer ring. A valve includes a valve member connected to a valve body by the flexure.

Abstract: A flexure for a metering valve has a flexure body defining a center axis to be aligned with a fuel nozzle. The flexure body includes an outermost peripheral surface surrounding the center axis. A retaining feature is formed in the flexure body and is configured to mount the flexure body to a metering valve component. The retaining feature is located radially between the center axis and the outmost peripheral surface. A metering valve is also disclosed.

Abstract: A fuel control system includes a high pressure relief valve fluidly connected to a fuel pump outlet. The high pressure relief valve includes a closure and a nozzle. The closure has an opening and a locking notch defined by a circumferential wall. The nozzle has a base portion that is received within the opening and has a rim extending between a first surface and a second surface. The nozzle has a tab extending from the rim that is received within the locking notch.
