摘要：Apparatus is provided to supply a liquid, for example water, at a constanttemperature, for example to a shower by mixing two supplies of the liquid, one hot andthe other cold. Control of the output temperature is effected by measuring andcontrolling the flow rate in one or both of the supplies by way of flow meters having arapid response time and motor driven valves.

In the case where the flow rates in both supplies are measured and controlled it ispossible further to control the output flow rate in addition to and independently fromthe output temperature, also by controlling the flow rates in the supplies.

Further accuracy may be achieved by sensing the input supply temperatures inaddition to the flow rates.
