関用噴射弁のシール油供給装置。 A seal that supplies fuel gas to the valve chamber provided at the tip of the needle valve of a gas engine injection valve and an annular groove provided in the middle of the sliding part between the valve sheath that houses the needle valve and the needle valve. The sealing oil is communicated to the cylinder chamber on the side with the smaller pressure receiving area among the cylinder chambers which are housed in a cylinder so as to be able to reciprocate inside the cylinder and are equipped with pistons having different pressure receiving areas on both sides. A gas engine characterized in that the oil pressure of the seal oil is always made larger than the gas pressure of the fuel gas at a constant ratio by communicating the fuel gas to the cylinder chamber on the larger side of the engine. Seal oil supply device for injection valves.
