Patent ID: 8037862

Claim:
An internal combustion rotary engine having an engine chamber defined by a chamber wall and a rotor valve body in three locus-sealing contact with said chamber wall to define a series of three subchambers including a first subchamber for sequential compression, transfer, and combustion of a fuel mixture from a chamber fuel mixture intake and for exhausting combustion products through a chamber exhaust outlet; said rotor valve body defining a rotor first bodily internal path for fuel mixture travel from said chamber fuel mixture intake to said first subchamber for said compression and combustion to combustion products, and a rotor second bodily internal exhaust travel path between said combustion products in said first subchamber and said chamber exhaust outlet for exhausting of said combustion products, said chamber wall and said rotor valve body cooperating to transfer compressed fuel mixture past said rotor valve body within said first subchamber, said rotor valve body further defining a sealing and sliding valve structure with said chamber wall for controlling intake into and exhaust from said first subchamber; said rotor valve body centrally connected to intake side and exhaust side crank plates journaled in opposite side walls, said intake side and exhaust side crank plates coupled to drive an output shaft as the intake side and exhaust side crank plates rotate on their respective axes; said fuel mixture intake extending through said intake side crank plate to a fuel mixture intake port into said engine chamber, said rotor first bodily internal path including an arcuately extended intake recess registerable with said fuel mixture intake port to control said fuel mixture into said first subchamber, said chamber exhaust outlet extending from an exhaust port from said engine chamber through said exhaust side crank plate, said rotor second bodily internal path including an arcuately extended exhaust recess selectively registerable with said exhaust port to control said exhaust from said first subchamber.
