ABSTRACT:
An improved cooling system for a rotary engine rotor, having coolant channels provided between the rotor body and the rotor bearing race. The coolant channels interconnect coolant passages provided at each of the triangularly-shaped rotor's apices. Provided in each of the coolant passages are coolant ribs which not only facilitate heat transfer between the coolant and the rotor, but, by preferential positioning, further aid in directing the coolant into and out of the coolant channels.
