A piston pump assembly for a hydraulic vehicle brake system having an electric motor and, coaxially to that, a planetary gear, a ball-screw drive and a piston-cylinder unit, in which a piston is connected in a rotatably and axially fixed manner to a spindle of the ball-screw drive and guiding the piston in a rotatably fixed manner in the cylinder, so that the spindle (20) is retained in a rotatably fixed manner. Also, the planetary gear is mounted in a pot-shaped planetary-gear housing that is disposed on a ball bearing which is used for a rotational mounting of a spindle nut on a cylinder of the piston-cylinder unit.
