[Scope of Claim for Utility Model Registration] (1) To return surplus fuel from the fuel reservoir of a fuel injection pump to the fuel tank and to remove air from the fuel reservoir, which appropriately supplies fuel sent from the oil feed pump to the engine. The automatic air venting device for a fuel injection pump is provided with a surplus fuel return device body that engages with an opening formed in the fuel reservoir chamber, and the surplus fuel return device body is provided with an orifice formed in the surplus fuel return device body. An automatic air venting device for a fuel injection pump, characterized in that surplus fuel and air are returned to the fuel tank. (2) The surplus fuel return device main body includes an eye bolt and an eye, a fuel return passage formed in the axial center of the eye bolt communicates with the fuel reservoir chamber, and an orifice opening into the fuel return passage. Claim 1 of the Utility Model Registration Claim, characterized in that an orifice is formed on either the eye bolt or the eye, and excess fuel and air in the fuel reservoir chamber are sent to the fuel tank through the orifice. An automatic air bleed device for a fuel injection pump as described in . (3) The surplus fuel return device main body includes an eye bolt and an eye, which communicates a fuel return passage formed at the axial center of the eye bolt with the fuel reservoir chamber, and a first opening into the fuel return passage. forming an orifice in the eye bolt;
and a second orifice communicating with the first orifice is formed in the eye, and surplus fuel and air in the fuel reservoir chamber are sent to the fuel tank via the first and second orifices. Claim 1 for utility model registration characterized by
Automatic air bleed device for fuel injection pumps as described in 2.
