摘要：
The invention relates to a pressure regulator for a fuel supply system of an internal combustion engine for regulating a fuel pressure. Said regulator comprises a valve, which contains a valve ball that is displaced into a closing position against a valve seat by the action of a valve plate spring. The invention is characterised in that one section (31) of a hemisphere, facing towards the valve plate spring (16), of the valve ball (18) projects into a recess (37) that is allocated to the valve plate spring (16). This improves the acoustic and regulatory behaviour of the pressure regulator.
