An ignition coil for an internal combustion engine has a housing composed of synthetic plastic material, at least one main core provided with a coaxial primary and secondary coils, a return flux core surrounding the main core, a dome extending from the housing and having a high voltage connection connected with the secondary coil and associated with a spark plug of an internal combustion engine. The main core and the return flux core are composed of a plurality of coated lamellas. The return flux coil is provided with recesses extending through the lamellas for passage of mounting means for the ignition coil, the recesses each being coated with a bushing. The bushings are formed as synthetic plastic injection molded parts which are connected of one-piece with a synthetic plastic jacket of the return flux core.

Ignition coil for an internal combustion engine

A pressure regulating apparatus which serves to regulate fuel pressure in a fuel injection system for internal combustion engines. The pressure regulating apparatus includes a pressure regulating valve, which has a valve diaphragm fastened in a valve housing and defining a fuel chamber, which communicates via an inlet conduit with a fuel distributor line. Protruding into the fuel chamber is a valve seat carrier body having a valve seat body, on which a valve seat is embodied, from which an outlet conduit leads to an outlet fitting. The pressure regulating valve is inserted into a holder bushing communicating with the fuel distributor line and is sealed off therefrom by a sealing ring disposed on the regulating valve. The axial fixation of the pressure regulating valve in the holder bushing is effected via a screw connection with a retaining body.
