The invention relates to a hydraulic piston pump, particularly for a slip-controllable vehicle braking system. A piston pump according to the invention includes a hydraulically permanently permeable stopper, the throughflow of which is carried out as a function of the pressure in an outflow channel of the piston pump. A pressure medium flow only takes place if the pressure level in the outflow channel has exceeded a threshold value. The latter takes place, for example, if the kinematic viscosity of the flowing pressure medium decreases due to low ambient temperatures, or if a throughflow of the outflow channel is obstructed. By means of the proposed solution, excess pressure increases in the interior of the piston pump can be avoided, and the resulting loads for the pressurized pump components and the drive can be reduced. Otherwise, the operating behavior of the piston pump according to the invention corresponds to that of a known piston pump.
