A safe mountability of a radial seating ring without mistakes, in which the radial sealing ring comprises a spring steel sheet, coated with an elastomer and having a cross section of undulating course, with at least one bulge pointing toward the interior of the sealing ring and at least one bulge pointing outward in the opposite direction, for contact with parts to be sealed off.

Radial sealing ring and method for producing it

The invention is based on a fuel injection pump in which to supply a very rapid pressure rise in the interior of a fuel injection pump, a pressure valve controlling this pressure is modified such that upon cold starting of the engine, the pressure valve closes a bypass line at the feed pump and thus delivers all the fuel to the fuel injection pump. The closure is effected as a function of rpm and accordingly pressure, and also as a function of the engine operating temperature; in the fuel injection pump according to the invention, the rpm- and pressure-dependent diversion is performed by the adjusting piston of an injection adjuster. Thus, compared with the known cold-starting accelerating devices, one additional pressure limiting valve can be eliminated.
