Ventil und verfahren zur steuerung des flüssigkeitsstroms zwischen einer flüssigkeitszufuhrvorrichtung und einer flüssigkeitsaufnahmevorrichtung

Abstract

A valve (20) and a method of controlling fluid flow between a fluid supplying device and a fluid receiving device, the valve having an inlet (11) for connection to the fluid supplying device, and an outlet (13), wherein the valve comprises a piston arrangement (21) slida-ble with respect to a valve body (12) between a closed first position, and an open second position providing fluid communication between the inlet and the outlet upon exposure to a fluid pressure exceeding a predetermined level, wherein the piston arrangement has a first piston area when the valve is in the closed first position, and an additional second piston area when the valve is in the open second position, and wherein the valve further comprises a restrictor arrangement (40) for delaying closing of the valve to allow a fluid supply pressure to bleed off.
