Abstract
Official abstract text for this publication.
Electromagnetic valve, particularly for controlling a fuel injector or for regulating the pressure of a high-pressure fuel accumulator, comprising a casing ( 2 ), an electromagnet ( 24, 25 ) formed of a yoke ( 24 ) and an electromagnetic coil ( 25 ) housed in the latter, and an armature ( 22 ) in one or more parts. An abutment disk ( 28 ) is provided between the transverse face of the armature ( 22 ) turned towards the yoke ( 24 ) and the transverse face facing the yoke ( 24 ), this abutment disk ( 28 ) being made of a magnetized or magnetizable material, particularly of a ferromagnetic material.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electromagnetic valve, comprising: a casing ( 1 , 2 ), an electromagnet ( 24 , 25 ) formed of a yoke ( 24 ) and an electromagnetic coil ( 25 ) housed in an opening of the yoke, and an armature ( 22 ) in one or more parts, the yoke ( 24 ) opening towards the armature ( 22 ), characterized in that an abutment disk ( 28 ) is provided between on one hand a transverse face of the armature ( 22 ), said face of the armature ( 22 ) being turned towards the yoke ( 24 ), and on the other hand a transverse face of the yoke ( 24 ), the abutment disk ( 28 ) being made of a magnetized or magnetizable material, and in that a bearing surface of the abutment disk ( 28 ) is reduced by at least two orifices ( 34 , 35 , 36 ), wherein at least one of the at least two orifices ( 36 ) has a different size than the remaining orifices ( 34 , 35 ), characterized in that the bearing surface of the abutment disk ( 28 ) is further reduced by a central drill hole ( 36 ).
