Abstract (en)

[origin: WO2012048984A1] The invention relates to a high-pressure pump for a fuel injection device of an internal combustion engine, comprising at least one pump piston driven by the rotation of a drive shaft about a rotary axis via a cam disposed on the drive shaft and a plunger assembly disposed on the pump piston, in a stroke motion in a substantially radial direction to a rotational axis of the drive shaft, wherein the plunger assembly comprises a roller having a roller shell surface making contact with a running surface of the cam, wherein the running surface of the cam and/or the roller shell surface at least partially has a coating comprising an elastomer. The invention further relates to a drive for a high-pressure pump, comprising a drive shaft having at least one cam and a roller disposed in a roller shoe, wherein a roller shell surface of the roller makes rolling contact with a running surface of the cam, wherein the running surface of the cam and/or the roller shell surface of the roller at least partially has a coating comprising an elastomer.
