Abstract:
A flow limiter device for liquid delivery systems comprising:a pipe having a liquid inlet and a liquid outlet, said pipe including a first chamber connected to the inlet, and a second chamber downstream of the first chamber and connected to the outlet,a valve member mounted in the pipe and movable between(1) a flow-limiting position, in which the valve member is located within the first chamber and limits liquid flow to a predetermined limited-flow rate while liquid flow is allowed into and through the first chamber, and(2) a full-flow position displaced downstream from the flow-limiting position in which the valve member is located within the second chamber and allows liquid flow at a greater full-flow rate through the first chamber and the second chamber to the outlet,a mobile control element in operative engagement with and holding the valve member in the flow-limiting position and which is actuable to move from operative engagement with the valve member and free the valve member,liquid acting on the valve member producing a liquid-pressure force which, when the valve member is free, moves the valve member from the flow-limiting position to the full-flow position.
