Abstract
The invention relates to a piston pump for a slip-controlled hydraulic vehicle brake system. For the sake of a short structural length of the piston pump, piston of the piston pump is a hollow piston, whose interior forms a positive displacement chamber of the piston pump. The piston can be produced economically as a reshaped part, for instance by deep drawing.
