A shower head providing an improved pause mode that restricts the amount of water emanating from the head. The shower head includes a first and second outlet nozzle, a valve body operative to be in fluid communication with a shower pipe, the valve body having first and second flow channels in fluid communication with the shower pipe, each of which is also in fluid communication with one of the outlet nozzles. The first and second flow channels have different cross-sectional areas. In another embodiment, the valve body further includes a valve center in fluid communication between the first flow channel and the shower pipe, and is also in fluid communication between the second flow channel and the shower pipe. The valve body further defines a first hole in fluid communication with the first flow channel and the valve center, and a second hole in fluid communication with the second flow channel and the valve center, with the second hole having a smaller cross-sectional area than that of the first hole.
We claim: 1. A shower head comprising: a first and second outlet nozzle; a valve body comprising: a valve center defined in the valve body; a first flow channel in fluid communication with the first outlet nozzle; a second flow channel in fluid communication with the second outlet nozzle; a first h
We claim: 1. A shower head comprising: a first and second outlet nozzle; a valve body comprising: a valve center defined in the valve body; a first flow channel in fluid communication with the first outlet nozzle; a second flow channel in fluid communication with the second outlet nozzle; a first hole in fluid communication with the first flow channel and the valve center, and a second hole in fluid communication with the second flow channel and the valve center; a first plunger residing within the first flow channel, the first plunger configured to move within the first flow channel to alternately allow and prevent liquid from flowing through the first flow channel; and a second plunger residing within the second flow channel, the second plunger configured to move within the second flow channel to alternately allow and prevent liquid from flowing through the second flow channel; and an actuator ring operably connected with the first plunger and the second plunger; wherein the first hole has a first cross-sectional area, and the second hole has a second cross-sectional area less than the first cross-sectional area. 2. The shower head of claim 1, wherein: the actuator ring comprises an actuation point; the first and second flow channels are arranged radially about the valve center; the actuator ring is configured to force the first plunger towards the valve center when not aligned with the actuation point, thus preventing the flow of liquid through the first flow channel; the actuator ring is configured to force the second plunger towards the valve center when not aligned with the actuation point, thus preventing the flow of liquid through the second flow channel; the first plunger is configured to radially outwardly extend from the valve center when aligned with the actuation point, thus allowing the flow of liquid through the first flow channel; and the second plunger is configured to radially outwardly extend from the valve center when aligned with the actuation point, thus allowing the flow of liquid through the second flow channel. 3. The shower head of claim 2, wherein: liquid pressure acts to radially outwardly extend the first plunger when the first plunger is aligned with the actuation point; and the liquid pressure also acts to radially outwardly extend the second plunger when the second plunger is aligned with the actuation point. 4. The shower head of claim 3, wherein the required torque to be applied to the actuator ring to force the first plunger toward the valve center is substantially equal to the required torque to be applied to the actuator ring to force the second plunger toward the valve center.
