Title:
内燃機関用の燃料噴射弁の弁ニードルにおける絞り
Document Type and Number:
Japanese Patent JP2010533263
Kind Code:
A
Abstract:
The invention relates to a fuel injection valve for internal combustion engines, having a valve body, in which a pressure chamber is configured. A valve needle is disposed in the pressure chamber in a longitudinally displaceable manner. The valve body has a valve seat which interacts with a sealing surface configured on the valve needle. The valve seat delimits the pressure chamber, thus enabling or interrupting a fuel flow to at least one injection opening by the interaction of the valve needle with the valve seat. To this end, the fuel flow to the injection openings occurs between the valve needle and the wall of the pressure chamber, through a sharp-edged gap throttle which is formed between the valve needle and the wall of the pressure chamber.
