Abstract

A shower assembly ( 10 ) including a shower head ( 11 ) to receive water from a cold water tap ( 12 ) and a hot water tap ( 13 ). Each of the taps ( 12, 13 ) has a tap body ( 20 ) within which there is located a flow restriction device ( 23 ). A further flow restriction device ( 33 ) is located downstream of the two flow restriction devices ( 23 ).

Claims

exact text as granted — not AI-modified
1 . A flow control assembly for a shower head that is to receive hot water from a hot water inlet and cold water from a cold water inlet, said assembly including: 
 a first flow restriction device to be operatively associated with the cold water inlet to restrict flow emanating therefrom;    a second flow restriction device, said second device to be operatively associated with the hot water inlet to restrict the flow emanating therefrom;    a pipe extending from the two devices so as to receive water therefrom and to deliver the water to the shower head; and    a third flow restriction device, said third device being downstream of the first and the second device so as to restrict the flow of water to the shower head.    
   
   
       2 . The flow control assembly of  claim 1 , wherein said third flow restriction device is a variable orifice device, with the orifice thereof being caused to close with an increase in water pressure delivered to the third device.  
   
   
       3 . The flow control assembly of  claim 1 , wherein the first and second devices are fixed orifice water restriction devices.  
   
   
       4 . The flow control assembly of  claim 2 , wherein the hot water inlet includes a hot water tap and the cold water inlet and a cold water tap.  
   
   
       5 . The flow control assembly of  claim 2 , wherein said hot water inlet and cold water inlet are included in a mixer tap.  
   
   
       6 . The flow control assembly of  claim 3 , wherein the hot water inlet includes a hot water tap and the cold water inlet and a cold water tap.  
   
   
       7 . The flow control assembly of  claim 3 , wherein said hot water inlet and cold water inlet are included in a mixer tap.
