Abstract
Cooling a hot component such as a rotor of a rotary piston engine by passing a coolant liquid through a passageway defined between adjacent surfaces of the component and a plug inserted into a socket in the component, the plug being made of a material having greater thermal conductivity than that of the material from which the component is made and the cross-sectional area of the passageway being sufficiently small as to produce turbulent flow of the coolant through the passageway.
