VALVE SEAT FOR GASEOUS FUEL INJECTOR

摘要

A gaseous fuel injector for supplying gaseous fuel to a fuel consuming device includes a fuel inlet, a fuel outlet, a fuel passage for communicating the gaseous fuel from the fuel inlet to the fuel outlet and a valve assembly for selectively preventing and permitting the gaseous fuel to pass from the fuel inlet to the fuel outlet. The valve assembly includes a valve seat with a plurality of apertures for providing fluid communication therethrough and a valve extending along a valve axis for selectively preventing and permitting flow of the gaseous fuel through the valve seat. Each one of the plurality of apertures is a radially extending slot and the plurality of apertures is arranged in a polar array centered about the valve axis.

1. A gaseous fuel injector for supplying gaseous fuel to a fuel consuming device, said fuel injector comprising:
a fuel inlet for receiving said gaseous fuel; a fuel outlet for dispensing said gaseous fuel from said fuel injector; a fuel passage for communicating said gaseous fuel from said fuel inlet to said fuel outlet; and a valve assembly for selectively preventing and permitting said gaseous fuel to pass from said fuel inlet to said fuel outlet, said valve assembly comprising:
a valve seat with a plurality of apertures for providing fluid communication through said valve seat;a valve extending along a valve axis and having a sealing face for selectively preventing and permitting flow of said gaseous fuel through said valve seat by selectively engaging and disengaging said valve seat;wherein each one of said plurality of apertures is a radially extending slot and said plurality of apertures is arranged in a polar array centered about said valve axis.
