摘要：<p>A valve assembly comprising a chamber (17), the chamber (17) having an inlet which is adapted to be connected to a source of relatively high pressure fluid, and an outlet which is adapted to be connected to a source of relatively low pressure fluid, and a switch valve (37) which is switchable between a first configuration in which the valve (37) closes the outlet and opens the inlet, and a second configuration in which the valve (37) closes the inlet and opens the outlet, characterised in that a flow control device (44) is provided between the outlet and the volume of relatively low pressure fluid, the flow control device (44) including a restrictor portion which restricts flow of fluid through the flow control device (44), the extent to which fluid flow is restricted decreasing as the fluid pressure in the chamber (17) increases.</p>
