Title: ROTARY ENGINE
Abstract:
A rotary engine of the present invention comprises: a housing having a plurality of lobe receiving portions disposed therein; a rotor rotated while being disposed eccentrically from the center of the housing, and having lobes successively received in the lobe receiving portions; a housing cover coupled to the housing while overlapping the lobe receiving portions; and a sealing unit for sealing each of the lobe receiving portions, wherein the sealing unit comprises: rolling seals protruding from the rotor so as to slide on the housing cover; lobe seals protruding from the housing so as to separate the adjacent lobe receiving portions from each other; and corner seals protruding from each of the lobe seals, extending between the housing cover and the rotor, and elastically supported on the rolling seals. Accordingly, the varying gap between each lobe seal and each rolling seal can be effectively sealed.
