Claim:
1. A hydrostatic piston engine comprising: a rotor; a brake device configured to produce a braking force on the rotor; an actuating element configured to actuate the brake device, the actuating element configured to release the brake device when a hydraulic force is applied on a surface of the actuating element in a pressure space, the pressure space connected via a first throttle point to a pressure medium source, and the pressure space configured to be connected to a pressure medium sink; and a pressure-holding valve device configured to open in a direction of the pressure medium sink and arranged between the pressure space and the pressure medium sink, wherein an opening pressure of the pressure-holding valve device is at least equal to a pressure in the pressure space which is required to release the brake device, wherein a second throttle point is formed parallel to the pressure-holding valve device, and wherein the pressure space is connected to the pressure medium sink via the second throttle point.
