| TRACED FROM LeC 3488. WE HAVE CHEAPENED THE INTERNAL CONSTRUCTION OF THE REGULATOR BY DELETING THE PRESSURE BALANCE VALVE. THIS IS THE ONLY MODIFICATION IN THIS SCHEME. WE ANTICIPATE THAT THIS MODIFICATION WILL RESULT IN A DELAYED CLOSING OF THE TOP VALVE, OWING TO THE PRESSURE DIFFERENCE CREATED BY THE WATER PUMP, WHICH TENDS TO PREVENT THE THERMOSTAT FROM CLOSING AS THE TEMPERATURE FALLS. PRESS IN BUSH. VALVE GUIDE IS LOCATED BY PLAIN PORTION AND RETAINED BY HEX NUT WHICH IS TO BE LOCKED BY SWEATING. SCALE 1/1 BENSPORT MODN. TO WATER TEMP REGULATOR. Le.C.3569 ROLLS ROYCE LTD.
