The invention relates to a high pressure pump (1) for the fuel supply device of an internal combustion engine (30). The high pressure pump comprises a storage tank side low pressure area (8); a pressure generation unit (3), which is connected to the storage tank side low pressure area and is used to supply pressurized fuel to an engine side high pressure area (9); and a pressure damper (15), whichhas a damper inner space (16) that can be elastically enlarged and is connected to the low pressure area (8). The high pressure fuel supply device has an optimized structure. The invention provides ahigh pressure pump with a high voltage energy accumulator (17). The high voltage energy accumulator (17) is designed to store a pressurized fuel and is connected to the high pressure area (9) throughat least one valve (22, 24). 本发明涉及一种用于内燃发动机(30)的燃料供应装置的高压泵(1)，其具有：储槽侧低压区域(8)；与其连接的压力生成单元(3)，以用于为发动机侧高压区域(9)供应加压燃料；以及压力阻尼器(15)，其具有可弹性扩大的阻尼器内部空间(16)，该压力阻尼器(15)连接到低压区域(8)。为了提供具有优化构造的高压燃料供应装置，根据本发明提供了具有高压蓄能器(17)的高压泵，该高压蓄能器(17)被设计用
