ABSTRACT:
A method in which a valve part consisting of a valve seat body and a support body with injection holes is pushed into a longitudinal orifice of a housing and firmly connected to a wall of the housing with the insertion depth determining the presetting of a valve needle lift. The precise setting of the valve needle life is made on a fully assembled valve by deforming the valve part between fixing areas of the support body. The method of manufacture of the injection valve is particularly suitable for fuel injection units of mixture compressing engines with externally supplied ignition.
