摘要：The invention relates to a piston pump for conveying a fluid, in particular in avehicle brake system. The piston pump has a cylinder and a piston movably disposed inthe cylinder. A restoring element preloads the piston, and a drive unit for actuates thepiston in the cylinder to pump the fluid into a pressure chamber formed in the cylinder.
The piston is embodied by a first piston par and a second piston part. The first pistonpart is a cylindrical body, which can be moved by the drive unit. The second piston partform the piston base, in which four radial inlet openings and one axial connection openingfor communication with the pressure chamber are disposed. A flange for the dispositionof a seal is disposed on the outer circumference of the piston base element. Theopenings are simple to make in the face ends and circumferential regions of the secondpiston part.
