Planetary rotary engine with rotary ring valves

A rotary apparatus, said rotary apparatus comprising:

• a housing defining a housing chamber;
• four elliptical rotors, each one of said four elliptical rotors being mounted to a separate rotor shaft with said four elliptical rotors being rotatable within said housing chamber;
• a first intake valve disk mounted to one of said rotor shafts comprising an intake rotor shaft for rotation therewith, said first intake valve disk including an intake port extending between a first side and a second side of said first intake valve disk;
• a first exhaust valve disk mounted to another one of said rotor shafts comprising an exhaust rotor shaft for rotation therewith, said first exhaust valve disk including an exhaust port extending between a first side and a second side of said first exhaust valve disk;
• a valve plate, said valve plate including a first intake bore for rotationally receiving said first intake valve disk therein with said first intake bore defining a cylindrical sidewall, said valve plate further including a first exhaust bore for rotationally receiving said first exhaust valve disk therein with said first exhaust bore defining a cylindrical sidewall;
• said first intake valve disk and said first exhaust valve disk each including a radial edge wall with a groove disposed in said edge wall, and each including a ring member disposed in said grooves, said ring member of said first intake valve disk contacting said sidewall of said first intake bore when said first intake valve disk is disposed in said first intake bore, and said ring member of said first exhaust valve disk contacting said sidewall of said first exhaust bore when said first exhaust valve disk is disposed in said first exhaust bore;
• wherein said valve plate includes an inner side disposed toward said housing chamber and includes a first intake passage extending from said first intake bore to said inner side and a first exhaust passage extending from said first exhaust bore to said inner side, wherein said intake port of said first intake valve disk selectively aligns with said first intake passage when said first intake valve disk rotates within said first intake bore, and wherein said exhaust port of said first exhaust valve disk selectively aligns with said first exhaust passage when said first exhaust valve disk rotates within said first exhaust bore.

A rotary engine, said rotary engine comprising:

• a housing defining a housing chamber;
• a plurality of elliptical rotors, each one of said plurality of elliptical rotors being mounted to a respective rotor shaft with said plurality of elliptical rotors being rotatable within said housing chamber;
• at least one valve disk mounted to a respective one of said rotor shafts for rotation with said rotor shaft, said at least one valve disk having a first side and a second side with a port passing there between;
• a valve plate, said valve plate including a bore for rotationally receiving said at least one valve disk therein with said bore defining a cylindrical sidewall;
• said valve disk including a radial edge wall with a groove disposed in said edge wall, and including a ring member disposed in said groove, said ring member contacting said sidewall of said bore when said at least one valve disk is disposed in said bore;
• wherein said at least one valve disk comprises an intake valve disk and another valve disk comprises an exhaust valve disk, and said port comprises an intake port on said intake valve disk, and wherein said bore comprises an intake bore for receiving said intake valve disk, said exhaust valve disk being mounted to another said rotor shaft for rotation there with, said exhaust valve disk having a first side and a second side with an exhaust port passing there between, said valve plate including an exhaust bore for rotationally receiving said exhaust valve disk therein with said exhaust valve bore defining a cylindrical sidewall, said exhaust valve disk including a radial edge wall with a groove disposed therein, and including another ring member disposed in said groove of said exhaust valve disk with said ring member of said exhaust valve disk contacting said sidewall of said exhaust bore when said exhaust valve disk is disposed in said exhaust bore, and
• wherein said valve plate includes an inner side disposed toward said housing chamber and includes an intake passage extending from said intake bore to said inner side and includes an exhaust passage extending from said exhaust bore to said inner side, wherein said intake port of said intake valve disk selectively aligns with said intake passage when said intake valve disk rotates within said intake bore, and wherein said exhaust port of said exhaust valve disk selectively aligns with said exhaust passage when said exhaust valve disk rotates within said exhaust bore, and wherein said valve plate is mounted to said housing and said intake passage angles inwardly from said intake bore toward said inner side of said valve plate and said exhaust passage angles inwardly from said exhaust bore toward said inner side of said valve plate, with said intake passage and said exhaust passage angling toward a center of said housing chamber.
