Abstract
A fuel pressure regulating valve for motor vehicles which decreases, the noise behavior of pressure regulating valves frequently found to be annoying. The pressure regulating valve includes a sealing gap, a first part, and a second part of a connection opening which are dimensioned so that the noise behavior of the pressure regulating valve is significantly better than that of known pressure regulating valves. The pressure regulating valve is particularly suited for fuel delivery systems of motor vehicles with an internal combustion engine.
