ABSTRACT:
A fill and bleed valve for filling a liquid cooling system has a single axially movable plunger, slidable within a central block bore, from a normal operating position to a filling position that opens the cooling system to a supply of coolant. The filling operation is continued until all air is purged from the system. The central block bore also retains a solid fill of coolant, and when shifted back to the normal operating system, no air is introduced into the system.
