1. A method for producing a piston pump having a housing, comprising:
producing a piston assembly configured to be guided displaceably in the housing, producing the piston assembly including:
producing a first rod-shaped piston element,
producing a second sleeve-shaped piston element, and
connecting the second sleeve-shaped piston element to the first rod-shaped piston element via a press fit with a stop edge for the housing on the second sleeve-shaped piston element positioned directly radially outwardly of the first rod-shaped piston element, wherein producing the second sleeve-shaped piston element includes arranging at least one transverse bore and a longitudinal bore which corresponds with the at least one transverse bore in the second sleeve-shaped piston element, and arranging the stop edge for the housing on the second sleeve-shaped piston element;
producing an inlet valve including a receiving element in which an inlet valve spring and an inlet valve sealing element are arranged, and
arranging an inlet valve seat corresponding to the inlet valve on the second sleeve-shaped piston element,
wherein, during machining of the second sleeve-shaped piston element, the press fit and the longitudinal bore are at least one of produced and finished.
