IPC: F02M61/20
Abstract: A fuel injector for gaseous fuel is provided. The fuel injector includes at least one valve having a valve seat and a plunger that engages the seat to prevent gaseous fuel flow and is displaced from the seat to permit gaseous fuel flow. Displacement of the plunger away from the seat to open the at least one valve is resisted by a first plunger control mechanism and then a second plunger control mechanism depending on the distance the plunger is lifted from the seat.

IPC: F02M63/00
Abstract: A fuel injector device for injecting fuel into a combustion chamber of an internal combustion engine is provided. Included in the fuel injector is a body having a chamber and a pilot valve assembly including a seat retainer configured to be detachably insertable into the chamber of the body. A pilot valve seat is disposed in the seat retainer and substantially enclosed by the seat retainer. A stator assembly is disposed in the seat retainer and at least partially enclosed by the seat retainer. The pilot valve seat and the stator assembly in the pilot valve assembly are replaceable as a single unit of the pilot valve assembly for the fuel injector.

Abstract: A fuel injector is provided comprising an outer housing, a nozzle housing disposed within the outer housing, a flow path between the outer housing and the nozzle housing, the flow path being coupled to a low pressure fuel source, and a circumferential gap in flow communication with the flow path and extending about a tip of the fuel injector between an outer surface of the nozzle housing and an inner surface of a combustion shield adjacent the injector tip. The circumferential gap is in flow communication with a drain gap between the outer housing and a bore for receiving the fuel injector, the drain gap routing the low pressure fuel away from the injector tip.
Abstract translation: 提供一种燃料喷射器，其包括外部壳体，设置在外部壳体内的喷嘴壳体，外部壳体和喷嘴壳体之间的流动路径，该流动路径联接到低压燃料源，以及流动连通的周向间隙 具有流动路径并且在喷嘴壳体的外表面和与喷射器尖端相邻的燃烧屏蔽的内表面之间围绕燃料喷射器的尖端延伸。 圆周间隙与外壳和用于接收燃料喷射器的孔之间的排水间隙流动连通，排出间隙使低压燃料远离喷射器尖端。

Abstract: A fuel injector for gaseous fuel is provided. The fuel injector includes a valve assembly with a first valve and a second valve. The first valve is actively controlled to permit and prohibit gaseous fuel flow through the first injector. The second valve is spaced from the first valve and passively controlled to open in response to the gaseous fuel flow though the first valve, and to close when the gaseous fuel flow is terminated by closing the first valve.
