    摘要: Fuel injection system having a feed pump by which fuel is pumped out of a fuel tank to the intake side of a high-pressure pump pumps fuel into a reservoir as a function of engine operating parameters. A fuel metering device is provided for adjusting the fuel quantity pumped into the reservoir by the high-pressure pump. An electrically actuated blocking valve is disposed between the feed pump and the high-pressure pump, and by means of this valve the high-pressure pump can be disconnected completely from the feed pump. By means of the blocking valve, it can still be attained that no fuel is pumped by the high-pressure pump even if the fuel metering device does not provide complete sealing.

    摘要: A radial piston pump, having a flange and a housing, a pump element in the housing, and an eccentric drive shaft that actuates a piston in the pump element radial to the drive shaft, which piston seals a pump volume which upon expansion, delivers fuel from an inlet chamber into the pump volume and upon contraction, exerts pressure on the fuel in the pump volume and conveys it out at a high pressure, having an inner chamber that contains the eccentricity, and having a parting plane that extends between the housing part and flange part and intersects the inner chamber and the inlet chamber. A one-piece flat seal is disposed in the parting plane and seals the inlet chamber, the inner chamber, and the environment of the radial piston pump in relation to one another.
