"Gaseous Fuel Injector"
Abstract: To prevent foreign materials such as dust or tar that are mixed in gas fuel from being attached to a portion of the orifice that is disposed for measuring the flow rate through the fuel through-hole in the injector of the gas fuel so that the flow rate of the fuel is prevented from decreasing. An injector 1 for gas fuel, in which an injector valve body 7 is moved up and down in an axial direction so as to contact or separate from a valve seat 11 held on a valve seat holder 10 having a fuel through-hole 9 that is arranged opposite to the lower side thereof, the fuel coming in from a fuel inlet 13 is intermittently transmitted to the fuel through-hole 9 at a predetermined interval and an orifice 14 for measuring flow rate is disposed in the fuel through-hole 9, featuring a coating layer 15 consisting of Ni-P plating containing fluorine resin particles applied to the inner surface of the orifice 14.

GASEOUS FUEL INJECTOR
BACKGROUND OF THE INVENTION Field of the Invention
[0001]
The present invention relates to an injector injecting gas fuel such as LPG to an intake passage of an internal combustion engine. Description of the Related Art
[0002]
In the related art, an injector is used in which a predetermined amount of fuel gas is injected continuously at a predetermined interval to an intake passage in the internal combustion engine using a gas fuel such as LPG, as shown in Figs. 3 and 4 is known. It is known that the injector 1 holds an electromagnetic coil 2 and is formed such that a flow rate adjustment screw 5 is arranged at the center of a coil holder -4 which holds the electromagnetic coil 2 and is built in the outer case 3, and an injector valve body 7 is reciprocably arranged in an axial direction via a spring body 6 at the lower end thereof. The electromagnetic coil 2 is operated ON-OFF to move the injector valve body 7 up and down according to a command from an ECU (not shown) via a conducting wire (not shown) connected to a connector 8. Accordingly, the injector valve body 7 contacts or separates from an injector seat 12 at the valve seat 11 hel
