Abstract
A water discharge device in the form of a showerhead is disclosed having multiple features including a rotating shutoff valve incorporated in the body of the device. Variable discharge patterns are achieved by rotation of a handle on the side of the device. These patterns include a vibrating spray, a columnar spray pattern and cone shaped spray pattern. All patterns are achieved at low flow rates.

A fluid flow control valve, comprising:
- a valve body with at least one fluid inlet and outlet therein;
