Abstract

This pressure regulator prevents unpleasant vibration of the closing body. In the pressure regulator, a friction spring that is simple to mount is provided, by means of which the vibration of the closing body can be suppressed or reduced. The pressure regulator is intended in particular for fuel supply systems of motor vehicles that have an internal combustion engine.
