Abstract
The invention relates to a piston pump for a slip-controlled hydraulic vehicle brake system. For a compact structure of the piston pump, an inlet valve and outlet valve in the form of check valves be disposed in a valve bore at a tangent to a cylinder bore of the piston pump in a pump housing. Aside from the advantage of a compact, space-saving design, the invention has the advantage of a small idle volume and thus good efficiency of the piston pump.
