Abstract: A fuel injection system for internal combustion engines includes a high-pressure accumulator acted on with highly pressurized fuel by a high-pressure delivery unit and in turn supplies fuel to fuel injectors. The fuel injection system has a pressure control valve, which is disposed between a high-pressure side and a low-pressure side and actuating a valve element. The pressure control valve is actuated by means of an electrical actuator. An end surface of the pressure control valve delimits the low-pressure region in the high-pressure accumulator and is sealed by means of a seal disposed on the low-pressure side.

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.
