ABSTRACT:
An improved apex seal for a rotary engine of the type having a housing with an interior wall and a rotor having plural apices within the housing. A plurality of apex seals are provided, one at each of the apices on the rotor, for establishing a seal between the rotor and the interior wall of the housing. Each of the seals is thin walled and hollow and further includes a fluid inlet and a fluid outlet. Conduits are provided in the rotor for directing a coolant through each of the seals via the inlets and the outlets so as to control seal temperature and thereby minimize seal wear.
