A piston pump includes a piston assembly which has a first piston element, a second piston element, and at least one transverse bore which corresponds to a longitudinal bore. The piston pump further includes a cylinder in which the piston assembly is guided in a longitudinally movable manner, and an inlet valve which includes a cage element, in which an inlet valve spring and sealing element are arranged, and a corresponding inlet valve seat which is arranged on the piston assembly. The inlet valve sealing element can be pressed sealingly into the corresponding inlet valve seat by means of a restoring spring in order to close off the longitudinal bore. The second piston element is configured as a sleeve made of a wear-resistant material, which accommodates axially acting power components. The inlet valve seat is disposed on a bending edge of the second piston element configured as a sleeve. The at least one transverse bore corresponding to the longitudinal bore is placed in the second piston element. The invention further relates to an associated braking system.

The invention relates to a hydraulic unit for a hydraulic vehicle brake system having anti-skid control. The hydraulic unit includes a hydraulic block and an electric motor for driving hydraulic pumps inside the hydraulic block. The hydraulic block and electric motor are joined at a circumferential joint. For connection, the invention provides that the electric motor is provided with a radial flange, which is overlapped by a surrounding bead of the hydraulic block. The bead is designed so that it overlaps, in a radial inward manner, the radial flange of the electric motor by a joining process, for example, a surrounding caulking. The electric motor is sealingly connected to the hydraulic block in a simple manner by the surrounding joining process.
