Coverley - Production Engineer} re Bentley Water Temperature Regulator. Please receive herewith:- LeC.4017 showing the experimental modifications to the thermostat. The object of the modifications is to avoid the trouble of corrosion affecting the working of the valve. What we have done is to put the bottom guide inside the bellows instead of immediately above, and we are asking for generous clearances on the guides at the top and bottom. The leakage hole in the valve is .093 dia. instead of two holes .137 dia. The amount of leakage here is a matter of experiment. E/JNR.{Charles L. Jenner} Drawing to BY.{R.W.
