  • DUAL-VALVE THERMOSTAT
    Publication number: 20130334328
    Abstract: A dual-valve reverse poppet thermostat for use in a vehicle cooling system. The thermostat includes a cup having a temperature sensitive element that actuates a piston causing the piston to move axially upwards. Movement of the piston initiates the gradual opening of a preliminary valve to initiate coolant flow and equalize pressure to open a main valve. The preliminary valve and main valve are biased towards a closed position by biasing spring members.
