Abstract

Es wird ein Stößel für eine Hochdruckpumpe, insbesondere zur Kraftstofförderung, vorgeschlagen. Der Stößel (52) dient zur zumindest mittelbaren Abstützung eines Pumpenkolbens (34) an einem Antrieb (12). Der Stößel (52) ist hülsenförmig ausgebildet und als Blechteil ausgebildet. Die Hochdruckpumpe weist ein Gehäuse (10) auf, in dem eine rotierend antreibbare Antriebswelle (12) und wenigstens ein Pumpenelement (32) angeordnet ist, das einen durch die Antriebswelle (12) zumindest mittelbar in einer Hubbewegung angetriebenen Pumpenkolben (34) aufweist, wobei sich der Pumpenkolben (34) über einen im Gehäuse (10) verschiebbar geführten Stößel (52) zumindest mittelbar an der Antriebswelle (12) abstützt. Der Stößel (52) ist hülsenförmig ausgebildet und als Blechteil ausgebildet.It is proposed a plunger for a high-pressure pump, in particular for fuel delivery. The plunger (52) serves for the at least indirect support of a pump piston (34) on a drive (12). The plunger (52) is sleeve-shaped and formed as a sheet metal part. The high-pressure pump has a housing (10) in which a drive shaft (12) which can be driven in rotation and at least one pump element (32) is arranged, which has a pump piston (34) driven at least indirectly by the drive shaft (12) in a stroke movement, wherein the pump piston (34) is supported at least indirectly on the drive shaft (12) by means of a plunger (52) displaceably guided in the housing (10). The plunger (52) is sleeve-shaped and formed as a sheet metal part.
