Faucet with secondary opening

摘要

The valve device (1) includes a valve body (2) defining a fluid flow duct (30) having a plug (20) disposed therein, the plug having a main flow opening (21) and being movable between a first position in which the main flow opening co-operates with the flow duct, and a second position in which the plug closes the duct. The plug further includes secondary flow means (22) offset relative to the main flow means and enabling the hydraulic characteristic of the valve device to be controlled.
