Abstract
A dual-adjustment flow limiting device includes an outer shell, an inner shell, a flow limiting member, and an adjustment mechanism. The outer shell defines a plurality of external ports. The inner shell defines a flow chamber and a plurality of internal ports communicating with the flow chamber and is fitted into the outer shell such that a communicating area is formed between the internal and external ports. The flow limiting member is disposed in the flow chamber of the inner shell and can be deformed in response to the pressure of a water flow entering the flow chamber to partially block the internal ports, so that the water flow entering the flow chamber can be restricted. The adjustment mechanism is provided at the outer and inner shells to adjust the communicating area, so that the water flow can be further restricted.
