Definitions

  • the invention relates to a high-pressure fuel pump for an injection system of internal combustion engines, with a pump housing, with at least one pump element and with a camshaft for driving the pump element.
  • the pump housing 1 is made in two parts.
  • the two parts of the pump housing 1 are in the FIGS. 1a and 1b labeled 1a and 1b.
  • the first hydraulic connection 45 consists of a multiplicity of interconnected bores and a groove 47 in the blocking vane 37, which is arranged on the pressure chamber 43 facing side thereof.
  • a metering device 49 is arranged in the first hydraulic connection. Accordingly, the embodiment is according to Fig. 1 equipped with a suction throttle control. However, the invention is not limited to high-pressure fuel pumps with such a control.
  • the excessively conveyed by the Sperrwügelpumpe fuel is a pressure control valve 63 and a bore 55, which in Fig. 1a is visible, again returned to the suction chamber 41.
  • the bore 55 also opens a fuel inlet 57, from which fuel from a fuel tank, not shown, enters the high-pressure fuel pump.
  • an electric prefeed pump (also not shown) is integrated between the fuel tank, not shown, and the fuel inlet 57.
