Document Type and Number:
Japanese Patent JP2003504551
Kind Code:
A
Abstract:
The present invention relates to a method for adjusting the valve lift of an injector, especially a fuel injector for mixture-compressing externally ignited internal combustion engines. The valve has a fuel intake, an energizable actuation device, which moves a valve needle having a valve closing component, a fixed valve seat formed on a valve seat element, with which the valve closing component interacts for opening and closing the valve, and a fuel outlet. Furthermore, the valve has a valve seat support provided with an internal longitudinal opening for accepting the valve needle. The valve needle executes a lift between a valve closing position and a valve opening position. The valve seat support is preformed having at least one radially-outward-protruding raised section. In order to change the lift of the valve needle, the raised section is plastically deformed in radial direction toward the longitudinal opening.
