A hydraulic pump, in particular an adjustable axial piston pump, has at least one piston () movable in a reciprocating manner in a longitudinal direction within a pump housing during operation of the hydraulic pump. The piston () has a link head (), a piston top () opposite the link head (), and at least one hollow chamber () surrounded at least partially by a piston housing () that substantially or completely terminates each hollow chamber () towards the outside. A piston () for such hydraulic pump is also provided.
