Abstract
A pressure regulator for a fuel supply system of an internal combustion engine for regulating a fuel pressure, including a valve, having a valve ball forced against a valve seat into the closing position by the action of a valve leaf spring. With the valve open, at least some of the fuel flow that flows around the valve ball is deflected against an impact face coupled with the valve leaf spring for generating a flow force oriented counter to the closing force of the valve leaf spring. As a result, the pressure regulating performance of the pressure regulator is improved.
