Abstract:
A rotary engine comprising, in combination:a housing having a fluid inlet valve and a fluid outlet valve formed therein;a combustion actuator operationally connected within the housing;a gas pressure sensor operationally connected within the housing;a temperature sensor operationally connected within the housing;a generally cylindrical driveshaft extending through the housing and having first and second tapered ends with first and second threaded recesses formed therein;a first plurality of drive shaft splines formed on the first tapered end of the driveshaft;a second plurality of drive shaft splines formed on the second tapered end of the driveshaft;a first rotor rotationally mounted in the housing on the driveshaft and having a first hub and a first pair of oppositely disposed partially hollow wings extending from the first hub;a second rotor rotationally mounted in the housing on the driveshaft having a second hub and a second pair of oppositely disposed partially hollow wings extending from the second hub;a first pair of oppositely disposed drive blocks pivotally mounted to the first rotor;a second pair of oppositely disposed drive bocks pivotally mounted to the second rotor;a first drive flange having a first splined central aperture mounted on the first end of the driveshaft, wherein the first splined central aperture splinedly interlocks with the first plurality of splines;a second drive flange having a second splined central aperture mounted on the second end of the driveshaft, wherein the second splined central aperture splinedly interlocks with the second plurality of splines;a first pair of oppositely disposed drive levers pivotally coupled to the first drive flange and operationally connected to the first pair of drive blocks to form a first parallelogram;a second pair of oppositely disposed drive levers pivotally coupled to the second drive flange and operationally connected to the second pair of drive blocks to form a second parallelogram;a first externally threaded fastener partially extending through the first central aperture and threadedly connected to the first threaded recess; anda second externally threaded fastener partially extending through the second central aperture and threadedly connected to the second threaded recess;an inner seal adjacently positioned between the first hub and the second hub and including an outwardly biasing member positioned between a fingered first seal portion and a complimentarily fingered second seal portion;a plurality of outer seals respectively positioned between each rotor wing and the housing, each outer seal having a web portion contoured to securely engage a rotor wing and a rail portion adapted to extend from the web portion inwardly over a wing and outwardly to engage the housing;a plurality of seal counterbalances, each counterbalance having a shaft member respectively pivotally mounted within a rotor wing and connecting a counterweight portion to an outer seal;wherein the first and the second rotors are rotated about 90 degrees relative to each other;wherein the first and second pair of wings at least partially overlap to define four chambers within the housing; andwherein rotors are adapted to oscillate relative to each other such that the volume of the chambers is not a constant.
