Abstract: The invention provides a cryogenic pump reservoir (100), for a cryogenic liquid to be fed to a pump (208), with an interior reservoir space (103) extending between a reservoir bottom (101) and a reservoir top (102) and comprising a liquid feeding region (104), which is positioned at a first distance from the reservoir bottom (101) in the direction of the reservoir top (102), and a liquid removing region (105), which is positioned at a second distance from the reservoir bottom (101) in the direction of the reservoir top (102), the second distance being greater than the first distance. It is provided that in the liquid feeding region (104) there is formed a liquid feeding opening (106), that the interior reservoir space (103) is at least partially divided in the liquid feeding region (104) by means of a dividing wall (106), which is arranged in such a way that one of its surfaces (107) is aligned in the direction of the liquid feeding opening (106.
