Abstract
Die Erfindung betrifft eine Hochdruckpumpe (1) mit einem Pumpengehäuse (2) und einem in das Pumpengehäuse (2) integrierten Hochdruckspeicher (4), wobei der Hochdruckspeicher (4) eine Hochdruckabdichtung (5) aufweist, wobei die Hochdruckabdichtung (5) im Pumpengehäuse (2) innenliegend angeordnet ist. Die Hochdruckpumpe (1) ist insbesondere als Kraftstoffhochdruckpumpe für moderne Common-Rail-Einspritzsysteme einsetzbar. The invention relates to a high-pressure pump (1) having a pump housing (2) and a high-pressure accumulator (4) integrated in the pump housing (2), the high-pressure accumulator (4) having a high-pressure seal (5), the high-pressure seal (5) in the pump housing (5). 2) is arranged on the inside. The high-pressure pump (1) can be used in particular as a high-pressure fuel pump for modern common-rail injection systems.
