用于低温燃料的活塞泵和燃料输送装置
摘要：
本发明涉及一种用于将低温燃料从存储箱(12)中输送到高压区域中的活塞泵(1)和燃料输送装置。所述活塞泵(1)具有可往复运动的泵活塞(2)，所述泵活塞在一端部上限界压缩室(3)并且在另一端部上限界至少一个压力室(5、7)，所述至少一个压力室能够以液压压力介质被加载。所述活塞泵(1)的泵活塞(2)实施为多件式的并且包括至少一个压力活塞(35)和压缩活塞(33)，其中，所述压力活塞(35)和所述压缩活塞(33)能够相对彼此运动。
摘要（英）：

The invention relates to a piston pump (1) and a fuel feeding device for transferring low-temperature fuel from a storage tank (12) to a high-pressure region. The piston pump (1) has a reciprocating pump piston (2). The pump piston has a compression chamber (3) at the upper limit of one end and at least one pressure chamber (5, 7) at the upper limit of the other end. The at least one pressure chamber can be loaded with a hydraulic pressure medium. The piston (2) of the piston pump (1) is implemented as a multi-piece and comprises at least one pressure piston (35) and a compression piston (33).The pressure piston (35) and the compression piston (33) can move relative to each other.
