A hydrostatic piston engine includes an actuating element configured to actuate a brake device to produce a braking force on a rotor of the piston engine. The actuating element is configured to release the brake device when a hydraulic force acts on the actuating element. The hydraulic force prevails in a pressure chamber which is connected to a pressure medium source via a first throttle point. The pressure chamber is also configured to be connected to a pressure medium sink. The hydrostatic piston engine also includes a pressure retention valve device configured to open in a direction of the pressure medium sink. The pressure retention valve device is disposed between the pressure chamber and the pressure medium sink. The opening pressure of the pressure retention valve device is at least equal to the pressure in the pressure chamber which is necessary to release the brake device.
