A gaseous fuel injector (10) for supplying gaseous fuel to a fuel consuming device (12) includes a fuel inlet (14), a fuel outlet (16), a fuel passage (18) for communicating the gaseous fuel from the fuel inlet (14) to the fuel outlet (16) and a valve assembly (20) for selectively preventing and permitting the gaseous fuel to pass from the fuel inlet (14) to the fuel outlet (16). The valve assembly (20) includes a valve seat (34) with a plurality of apertures (40) for providing fluid communication therethrough and a valve (42) extending along a valve axis (A) for selectively preventing and permitting flow of the gaseous fuel through the valve seat (34). Each one of the plurality of apertures (40) is a radially extending slot and the plurality of apertures (40) is arranged in a polar array centered about the valve axis (A).
