A vehicle piston pump is provided to reduce pulsation transmitted to a brake pedal at the time of braking by mounting an orifice to a valve seat for reducing the pressure of oil discharged via a hole of the valve seat. A vehicle piston pump includes a valve seat(50) formed with a hole(52) for discharging oil, a ball(60) for opening or closing the hole, an elastic element(65) for applying elasticity to the ball, an orifice(70) coupled with the valve seat for reducing the pressure of the discharged oil, and a cap(90) for supporting the orifice and the elastic element. |
