摘要： PURPOSE:To make the leakage of fuel out of a sealing member surely detectable as making up a fuel pump so as to prevent the leaked fuel from reaching up to the outside of an engine, in this internal combustion engine fuel pump with a leak detector being suitable in use as a high-pressure output fuel pump in particular. CONSTITUTION:In this internal combustion engine fuel pump with a sealing member 11 around a pump shaft 6, it is provided with a leak detector 13 consisting of a leaked fuel inducing means 14 conducting the leaked fuel out of the sealing member 11 to an inlet system 17 of the engine, b air-fuel ratio detecting means 15 detecting an air-fuel ratio of the engine, and a leakage judging means 16 which so judges as there is a possibility that a leakage in the sealing member might be produced if the air-fuel ratio detected in this detecting means 15 is at the more rich side than the reference air-fuel ratio conformed to the engine driving state.

摘要： PURPOSE:To enable vapor contained ion fuel near a fuel injection valve to be discharged quickly by interposing a switching valve in a branch passage communicated to a fuel tank by bypassing a fuel control means so as to control the switching valve to open at the time of starting an internal combustion engine. CONSTITUTION:The fuel forceibly fed from a fuel tank 2 by means of a fuel pump 5 is returned by means of a fuel channel 3 to the fuel tank 2 via a fuel pressure control means 10. On the other hand, a branch channel 13 is communicated to a fuel channel 3B on a branch point 13A between the fuel pump 5 and the fuel pressure control means 10, and bypasses the fuel pressure control means 10 and is communicated to the fuel tank 2. A switch valve 14 is interposed on the branch channel 13. A fuel injection valve 1 for internal combustion engine is provided on the fuel channel between the fuel pump 5 and the branch part 13A or on the branch channel 13 between the branch part 13A and the switch valve 14. The switch valve 14 is controlled by a switch valve control means 30 so that the valve is released at the time of starting the internal combustion engine. Vapor contained in the fuel is thus drained promptly.

摘要： PURPOSE:To prevent reduction of buffer performance caused by inertia force acting on a buffer piston during operation of an internal combustion engine. CONSTITUTION:Buffer pistons 62, 63 are energized to the flange parts 51, 52 sides of an eccentric sleeve 5 by a spring 64, and they are brought into contact with the cam surfaces 51a, 52a of the flange parts 51, 52 sides. When the eccentric sleeve 5 is rotated till the neighborhood of a maximum or minimum eccentric position, the buffer pistons 62, 63 are pushed into a hydraulic cylinder by the cam surfaces 51a, 52a, and oil is discharged from an oil chamber 64 to carry out eccentric action. The buffer pistons 62, 63 are provided in the hydraulic cylinder extending in the axial core direction of the crank shaft inserting hole of a connecting rod 6, and as a result, the pistons 62, 63 can not be moved in inertia force action direction so as to prevent reduction of buffer performance caused by their vibrations.
