Abstract
A reverse flow cooling system for an internal combustion engine wherein coolant flows first into the cylinder head cooling chamber and then downwardly into the cooling chambers surrounding the cylinders comprises a thermostatically controlled valve having a valve spool movable between spaced and aligned inlet and outlet ports to control flow therethrough. The inlet port and outlet ports of the valve are sized so as to exhibit a combined resistance to flow equal to or less than the resistance to flow of the inlet port whereby coolant flowing through said thermostat exhibits minimum pressure drop.
