A piston pump, in particular for a motor vehicle, includes a piston that is movably mounted in a housing. The piston pump further includes a linear actuator for moving the piston in a first direction. The piston pump further includes a return spring for moving the piston in a second direction. The end face of a first end of the piston delimits a first pressure chamber that is associated with a first hydraulic circuit. The end face of a second end of the piston delimits a second pressure chamber.
