  "textContent": "A pump device for a brake system of a motor vehicle has a housing, a pressure piston which delimits a pressure chamber in the housing for producing hydraulic pressure mounted in the housing in a longitudinally displaceable manner, a return spring assigned to the pressure piston, a non-return valve which separates the pressure chamber from a pressure connection and only removes the separation when the hydraulic pressure in the pressure chamber is greater than in the pressure connection, and an electromagnetic actuator which includes an armature and an electrically energizable solenoid. The armature is arranged on the pressure piston and the solenoid in and/or on the housing. The pressure piston has an axial through-channel which opens out into the pressure chamber at one end and is assigned to the non-return valve at the other end.",
