초록 ▼

An electromagnetic high-pressure injection valve is used in the direct injection of fuel into the combustion chamber of internal combustion engines. The magnetic valve has a miniaturized magnetic circuit in which the necessary actuating forces are reduced by means of a particularly small seat diameter and a small stop surface for the valve needle, in comparision with prior art constructions. Fuel under high pressure streams completely around the moving parts of the valve. An adjustable seat base is also provided which provides high long-term calibration stability, despite its small size. In order to reduce closing rebound, a vibration damping system may also be used in mechanical injection systems. In order to attain the fastest adjustments, the valve may be fitted with a polarized magnetic circuit having a special feature which is its suspension inside two diaphragm springs with a very steep elasticity characteristic.

대표청구항 ▼

An electromagnetic high-pressure injection valve for direct injection of fuel into a combustion chamber of an internal combustion engine, comprising a central valve axis, an electromagnet having an armature being completely surrounded by fuel under high pressure, a needle-shaped valve-closing body being firmly connected to said armature and having a non-pressure-balanced cross-section, a valve seat, a stop element having a stop surface being intersected by the central valve axis defining a contact area between said armature and said stop surface, said valve-closing body and said armature having a total mass of at most substantially 2.5 g, said valve-closing body being displaceable together with said armature along the central valve axis with a displacement being limited by said valve seat and by said stop element, and both said contact area and said non-pressure-balanced cross-section when said valve-closing body rests on said valve seat each being less than substantially 1 mm2.
