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. |
