摘要：
A fuel injection nozzle with a valve assembly having an inwardly opening check valve is provided with an elongated valve body to space the valve spring away from the nozzle. The valve spring is mounted in a housing which is provided with a spherical seating arrangement within the valve body which provides an effective sealing arrangement as well as self-centering of the valve with its seat regardless of machining variations.
