Abstract:
A charge cooled rotary engine comprising:a housing having an interior wall of a peritrochoidal configuration that is open at both ends, a first end plate secured to one end of the housing, and a second end plate secured to the opposite end of the housing, the housing and end plates defining a closed chamber;an elongated shaft extending through said closed chamber and having an eccentric disposed within said closed chamber;a rotor rotatably mounted to said shaft and in engagement with said eccentric, said rotor including three flanks forming a generally trochoidal shape, a cylindrical hub, and a web extending transversely from said hub and joining medial portions of said flanks to said hub, said web, flanks, and hub forming rotor cavities on opposite ends of said rotor, said rotor flanks serving to variously combine with said interior wall to define intake, compression, and combustion chambers;a first inlet passageway formed in said first end plate for receiving fuel/air charge and terminating in a first entry port facing said closed chamber;a second inlet passageway formed in said second end plate for receiving fuel/air charge and terminating in a second entry port facing said closed chamber;a first distribution chamber formed in said first end plate contiguous with said first entry port and open to said closed chamber;a second distribution chamber formed in said second end plate contiguous with said second entry port and open to said closed chamber;said first and second entry ports being positioned to directly communicate with said rotor cavities and to be substantially isolated from direct communication with any of said intake, compression, and combustion chambers by said rotor flanks;said first distribution chamber having a first inlet portion and a first side port portion, said first inlet portion being positioned to variously communicate directly with said first entry port via said rotor cavities subject to partial obstruction by said hub, said first side port portion being positioned to variously communicate directly with said intake chamber subject to partial obstruction by said rotor flanks; andsaid second distribution chamber having a second inlet portion and a second side port portion, said second inlet portion being positioned to variously communicate directly with said second entry port via said rotor cavities subject to partial obstruction by said hub, said second side port portion being positioned to variously communicate directly with said intake chamber subject to partial obstruction by said rotor flanks;whereby said fuel/air charge flows into said rotor cavities via said first and second entry ports to remove heat from both ends of said rotor before flowing to said intake chamber via said distribution chambers.
