Abstract

A fuel injection valve for internal combustion engines, having a valve member guided axially displaceably in a bore of a valve body. On an end of the valve member toward the combustion chamber, a valve sealing face is disposed, with which the valve member cooperates with a valve seat face on the valve body to control an injection cross section. At least one valve spring that acts upon the valve member and is inserted into a spring chamber is provided in a valve retaining body that is braced axially against the valve body. The spring chamber is closed on one end remote from the combustion chamber by a lid. The lid is secured to the valve retaining body by a crimped connection.
