Abstract
An engine-cooling system has each of the vent pipes connecting a geodetic high point with the expansion tank provided with a hydrodynamic flow-controlling throttle which provides substantially unobstructed flow to air and provides increasing flow resistance with increasing liquid flow throughput of the coolant-circulating pump.
