Showerhead or aerator containing pressure compensation device

摘要

Pressure compensators for stabilizing the flow of water are disclosed including at least one flow orifice (10) passing through a pressure compensator body (1) and at least one flexible flow controller (2) which can at least partially block the orifice (10) to provide it with a predetermined flow area whereby the flow controller flexes and reduces the flow area at increased water pressures. Flow controllers are also disclosed for controlling the flow of water including a revolving body (5) for selectively opening and closing a number of flow openings (17) therethrough.

主权项

1. A pressure compensator for stabilizing a flow of water comprising a pressure compensator body including an upper surface, a lower surface and an outer periphery, a plurality of flow orifices passing through the pressure compensator body from the upper surface to the lower surface thereof, and a plurality of flexible flow control members each capable of at least partially blocking an associated flow orifice to provide the flow orifice with a predetermined flow area, whereby the plurality of flexible flow control members are caused to flex and reduce but not close the predetermined flow area at increased water pressures, wherein each of the plurality of flexible flow control members comprises two flexible flow control flaps that project upwardly from the upper surface of the pressure compensator body.
