ABSTRACT:
A fuel injection system for internal combustion engines including a high-pressure reservoir which is acted upon by fuel at high pressure via a high-pressure feed unit and supplies fuel injectors with fuel. The high-pressure feed unit is assigned a pressure regulating valve which is disposed between a high-pressure side and a low-pressure side and includes a valve element which is triggerable via an electrical final control element. The pressure regulating valve includes a housing component which includes a deformable region by way of which, upon mounting of the pressure regulating valve on a receiving body, a gap L between faces of an electrically triggerable final control element assembly is adjustable.
