Abstract
A valve arrangement including a housing having a port, a closure member defining a bore, the bore being of a smaller flow area than an adjoining flow area to produce a lower pressure in flowing fluid therein than pressure in fluid flowing in the adjoining flow area, the closure member being disposed within the housing and movable between a closed position and an open position, a volume defined between the closure member and the housing, an opening in the closure member extending from the volume to the bore of the closure member to convey fluid pressure generated in the bore of the closure member to the volume thereby creating a lower pressure in the volume thereby biasing the closure member into a closed position.
