Abstract
Abstract A rotary internal combustion twin engine includes matching pairs of multilobed interengaging compression rotors compressing gas and air mixtures into compression chambers defined by concavities of transfer rotors. With a 180 degree rotation of transfer rotors, compression chambers become combustion chambers containing intermittent ignition devices. Ignited and expanded gasses impel lobes of matching pairs of multilobed interengaging expansion rotors providing rotational energy and exhausting burned gasses.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
108 words
A rotary internal combustion engine comprising: a housing of intersecting circular chambers, matching pairs of multilobed interengaging compression rotors mounted on shafts supported in said housing, a circular gas and air transfer rotor with concavities diametrically located on the periphery of said rotor defining alternating rotating compression and combustion chambers mounted on a drive shaft supported in said housing, a recessed ignition device in said housing, matching pairs of multilobed interengaging expansion rotors mounted on shafts supported in said housing, and rotary transmission means mounted on said shafts to transfer rotational energy between said rotors and to provide desired compression, desired expansion and sufficient exhaust of burned gasses.
Claim 2
Dependent Claim
108 words
A rotary internal combustion engine comprising: a housing of intersecting circular chambers, matching pairs of multilobed interengaging compression rotors mounted on shafts supported in said housing, a circular gas and air transfer rotor with concavities diametrically located on the periphery of said rotor defining alternating rotating compression and combustion chambers mounted on a drive shaft supported in said housing, a recessed ignition device in said housing, matching pairs of multilobed interengaging expansion rotors mounted on shafts supported in said housing, and rotary transmission means mounted on said shafts to transfer rotational energy between said rotors and to provide desired compression, desired expansion and sufficient exhaust of burned gasses.
