    • 专利摘要:
    A liquid fuel injection pumping apparatus for supplying fuel to an internal combustion engine comprises an injection pump to which fuel is supplied by a fuel pump. An air/fuel separator is provided and also a valve including a spring loaded piston for controlling the output pressure of the feed pump, the separator being connected to the outlet of the feed pump and the piston being subject to the output pressure of the pump. A space is defined in the pump housing and from which fuel can be drawn by the feed pump when the output pressure of the feed pump falls due to the entry of air into the feed pump. The air/fuel separator has a restricted outlet through which air and fuel can flow to an outlet in the housing and the space has an outlet which is placed in communication with the feed pump inlet by the piston.

    (5) FUEL INJECTION PRESSURE DEVICE
    The invention relates to mechanical engineering, in particular, to fuel injection injection devices for internal combustion engines, and can be used in fuel systems with a rotary fuel injection pump.
    A fuel injection device for an internal combustion engine is known, comprising a housing with an internal cavity, a rotary fuel injection pump located in the internal cavity, a fuel priming pump located in the housing and having an underwater and auxiliary 5 fuel channels, an air separation chamber located in the housing, which is connected an inlet channel with a diverting fuel channel of the fuel-priming pump, a lower outlet jo channel with a fuel-pressing pump and an upper output channel to through a choke with a drainage system, and a safety valve having a spring-loaded cylindrical locking element located in the cylindrical cavity of the housing and dividing the latter into a control volume communicated with the discharge channel of the fuel feed pump, and a controllable volume in which the spring is placed The control volume communicates with the underwater fuel channel of the fuel-priming pump through a discharge channel, the inlet of which is located on the lateral surface of the cylindrical plate. Lost when the pressure in the branch duct transfer pump rises above the set lj.
