ABSTRACT:
Structure providing improved cooling of the rotor of a rotary engine. The cooling structure includes flow passages for passing a portion of the bearing lubricant through the apices of the rotor. Radially extending portions of the flow passages may be provided in the end walls of the rotor. Delivery of the bearing lubricant to the rotor flow passages may be at one end of the bearing or at a mid-portion of the bearing as desired. The flow passages may include passages in the apices of the rotor extending between the end walls thereof and communicating at their opposite ends with radial passages in the end walls. In one form, the passages in the apices communicate at one end with a radial passage to a rotor cavity having an axial passage therefrom through the end wall at that end.
