A method is used to produce a piston pump having a housing and a piston subassembly. The piston subassembly is displaceably guided in the housing and has a first, rod-like piston element and a second, sleeve-like piston element. The second piston element is connected to the first piston element via a press fit. At least one transverse bore and a longitudinal bore are arranged in the second piston element. A stop edge for the housing is arranged on the second piston element. The piston subassembly also has an inlet valve, which includes a receiving element, in which an inlet valve spring and an inlet valve sealing element are arranged. The piston subassembly also has a corresponding inlet valve seat, which is arranged on the second piston element. While the second piston element is being machined, the press fit and the longitudinal bore are produced and/or finished in one step. |
