Abstract
A shower handset having teats formed in an elastomeric plate wherein positioning of the elastomeric plate behind the spray plate causes the teats to deflect outwardly, the cross-sectional areas of outlet orifices increasing in response to increasing flow rate.

4. A shower handset including:
-
an elastomeric plate having a base with an upstream and a downstream surface and a plurality of teats extending from said downstream surface in directions which are parallel when the elastomeric plate is unstressed;
a spray plate having an inner surface, an outer surface and a plurality of through holes corresponding to said teats, the downstream surface of said base being located adjacent said inner surface of said spray plate with said teats extending through said through holes;
the shower handset further including;
a support structure for holding the elastomeric plate adjacent said inner surface such that said base and at least a first one of said teats is deflected. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)

35. A method of constructing a shower handset having elastomeric teats, the method including:
-
moulding an elastomeric plate having a base with an upstream and a downstream surface and a plurality of teats extending from said downstream surface in directions which are parallel when the elastomeric plate is unstressed;
providing a spray plate having an inner surface, an outer surface and a plurality of through holes corresponding to said teats;
locating the elastomeric plate adjacent the spray plate with the downstream surface of said base being located adjacent said inner surface of said spray plate with said teats extending through said through holes;
providing a support structure for holding the elastomeric plate adjacent said inner surface such that said base and at least a first one of said teats is deflected.
