用于低温燃料的输送泵
摘要：
本发明涉及一种用于低温燃料(1)的输送泵(10)，其具有泵壳体(11)，泵活塞(25)以能够在泵腔(30)内往复运动的方式布置在所述泵壳体中，其中，所述泵活塞(25)借助活塞杆(26)与用于所述泵活塞(25)的驱动器(40)连接，其中，所述活塞杆(26)在所述泵壳体(11)的纵向孔(20)内在径向上被引导并且借助至少一个密封装置(60)相对于所述纵向孔(20)被密封，其中，所述至少一个密封装置(60)构造为，用于至少减少燃料从所述泵壳体(11)中流出。
摘要（英）：

The invention relates to a delivery pump (10) for cryogenic fuels (1), comprising a pump casing (11) inside which a pump piston (25) is arranged in such a way as to be able to reciprocate within a pump chamber (30); the pump piston (25) is connected to a drive (40) for the pump piston (25) by means of a piston rod (26) which is radially guided within a longitudinal bore (20) in the pump casing (11) and which is sealed from the longitudinal bore (20) by at least one sealing device (60), said at least one sealing device (60) being designed to at least reduce leakage of fuel (1) from the pump casing (11).
