PRESSURE LUBRICATION TO APEX CORNER SEAL ABSTRACT OF THE DISCLOSURE: A rotary internal combustion engine of the wankel type is disclosed. The engine has at least one epitrochoid chamber with flat side walls and an associated triangulated rotor cooperatively defining a plurality of variable volume chambers. An oil metering apparatus is integrated into the rotor for directing a jet of oil, preferably fed from a high pressure supply, against the side walls of the housing. The apparatus employs a biased plunger to distribute a controlled oil film about the housing side walls in cooperation with the eccentric path of the selected plunger location, preferably remote and independent from the dynamic seal grid system. The oil film is pumped by action of arcuate or annular side seal strips to migrate and coat intermetallic contact surfaces of the variable volume chambers. Oil consumption is reduced while providing a functional film at predetermined locations.
