Abstract
A multi-lobed trochoidal rotor for a trochoidal rotary engine includes main body defining at least two lobes, a trochoidal peripheral surface, side faces forming part of side faces of the rotor and a substantially central bore. Each side face of the body is recessed over each lobe and a plurality of the angularly spaced apertures in each lobe provide communication between the recessed part of each side face. Closure means neatly received in each recessed area complete a respective side face of the rotor. A plurality of passageways extend through the body, outwardly from the bore and include in each lobe at least one supply passageway and at least one return passageway terminating adjacent to an inner face respectively of a first and second closure means. Pressurized oil supplied to the bore is able to flow in each lobe through the at least one supply passageway, the plurality of apertures and the at least one return passageway, to an outlet adjacent the bore. A respective side seal groove extends circumferentially in each side face to receive a side seal for sealing with an engine housing in which the rotor is mountable.
