FUEL INJECTION APPARATUS MODULE

摘要

A fuel injection apparatus module where a fuel pump (11) and an injection pressure regulator (14) are integrally connected to an electric motor (10). The fuel pump (11) sends by pressure a fuel to an injector (13) by being driven by an output shaft (21a) of the electric motor (10), and the injection pressure regulator (14) regulates the pressure of the fuel injected by the fuel pump (11). An injector holder (47) for holding the injector (13) is integrally formed with a module body (40) connected to the fuel pump (11). A fuel passage (46) penetrating through each other the fuel pump (11), the injection pressure regulator (14), and the injector (13) is formed in the module body (40). This enables to eliminate a high-pressure fuel-guiding pipe between the injector and the fuel pump, remarkably reducing the cost of the fuel injection apparatus module.
