摘要： A fuel injector includes a housing, a passageway, a coil assembly, a seat, and a closure member. The housing extends along a longitudinal axis between an inlet and an outlet, and fuel flows through the passageway from the inlet to the outlet. The coil assembly is disposed proximate the inlet of the housing, and the seat is disposed proximate the outlet of the housing. The closure member is disposed in the housing and is movable along the longitudinal axis between a first position, which prohibits fuel flow, and a second position, which permits fuel flow. The closure member includes a magnetic member, a needle, and a tubular member. The magnetic member is adapted to cooperate with the coil assembly to move the closure member from the first position to the second position. The needle member occludes the seat in the first position of the closure member. The tubular member couples the magnetic member to the needle member, and defines a portion of the passageway. The tubular member extends between a first end, which defines a first opening, and second end, which defines a second opening. A portion of the first opening is aligned with the second opening such that fuel flow between the first and second openings is along a flow path that is parallel to the longitudinal axis.

摘要： A valve subassembly of a fuel injector that allows spray targeting and distribution of fuel to be configured using non-angled or straight orifice having an axis parallel to a longitudinal axis of the subassembly. Metering orifices are located about the longitudinal axis and defining a first virtual circle greater than a second virtual circle defined by a projection of the sealing surface onto the metering disc so that all of the metering orifices are disposed outside the second virtual circle. The projection of the sealing surface converges at a virtual apex disposed within the metering disc. At least one channel extends between a first end and second end. The first end is disposed at a first radius from the longitudinal axis and spaced at a first distance from the metering disc. The second end is disposed at a second radius with respect to the longitudinal axis and spaced at a second distance from the metering disc such that a product of the first radius and the first distance is approximately equal to a product of the second radius and the second distance. Methods of controlling spray distribution and targeting are also provided.
