Abstract

The pressure regulating valve (2) proposed here can be designed with the aid of the outflow throttle restriction (28) downstream of the valve seat (22) in such a way that the pressure regulating valve (2), as the fluid flow becomes greater, sets or adjusts a smaller pressure difference at the pressure regulating valve (2), as a result of which the line losses that can never be avoided can be compensated for. The pressure regulating valve is suitable in particular for a fuel supply system of a motor vehicle having an internal combustion engine.
