ABSTRACT:
The invention relates to a pressure regulator for a fuel delivery system of an internal combustion engine for regulating a fuel pressure, including a valve, which has a valve ball that is pressed against a valve seat in the closed position by the action of a valve leaf spring. A segment of a hemisphere of the valve ball oriented toward the valve leaf spring protrudes into a recess associated with the valve leaf spring. This improves the noise behavior and regulating behavior of the pressure regulator.
