Abstract

A rotary internal combustion engine comprising: a compressor section, a power section and a combustion chamber therebetween. The compressor section may comprise a pair of intermeshing gear members mounted in a compressor housing having an inlet on one side and a discharge on the opposite side. The intermeshing compressor gear members are mounted for rotation in opposite directions to compress and transfer air-fuel mixtures from the inlet to the discharge. The compressor discharge may be connected to the combustion chamber for combustion of the air-fuel mixture therein. The power section may comprise at least one rotor mounted in a housing having an inlet connected to the combustion chamber and through which expanding gases are directed against the periphery of the rotor for driving an output shaft connected thereto. The rotor may be connected to at least one of the compressor gear members for rotation thereof.

Dependent claims

A rotary internal combustion engine comprising a compressor section, a power section, and a combustion chamber therebetween;

said compressor section comprising a pair of intermeshing gear members mounted in a compressor housing, inlet means on one side of said compressor housing and discharge means on the opposite side of said compressor housing, said intermeshing compressor gear members being mounted for rotation in opposite directions to compress and transfer air-fuel mixtures from said inlet means to said discharge means;
said discharge means being connected to said combustion chamber for combustion of said compressed air-fuel mixtures;
said power section comprising at least one power rotor mounted in a housing having inlet means connected to said combustion chamber through which exploding gases are directed against the periphery of said power rotor for driving an output shaft connected to said power rotor, said power rotor being connected to at least one of said compressor gear members for rotation of said compressor gear members;
said power section comprising at least one valve rotor connected to said power rotor for cooperative rotation relative thereto, said power rotor being provided with a plurality of radial vanes projecting from the periphery thereof, said valve rotor being provided with valve ports which, upon rotation of said valve rotor, alternately permit and block flow of said exploding gases between said combustion chamber and the periphery of said power rotor, permitting said exploding gases to alternately expand against said power rotor vanes to rotate said power rotor, said power section being provided with exhaust means through which said expanded exploding gases may be selectively exhausted;
said valve rotor comprising a radial passage therethrough, each end of which terminates at the periphery of said valve rotor, providing communication between said power section inlet and said power rotor periphery at preselected time intervals related to the rotation of said power rotor and said valve rotor.

said compressor section comprising a pair of intermeshing gear members mounted in a compressor housing, inlet means on one side of said housing and discharge means on the opposite side, said intermeshing gear members being mounted for rotation in opposite directions to compress and transfer air-fuel mixtures from an air-fuel source to said combustion chamber for combustion therein;
said power section comprising a power rotor mounted in a cylindrical power housing and having radial vanes projecting therefrom, said power housing having inlet means through which expanding gases from said combustion chamber are directed against said power rotor vanes for effecting rotation of said power rotor, said cylindrical power housing having exhaust means in at least one end thereof communicating with the periphery of said power rotor and through which said expanded gases are exhausted;
and comprising valve means at said power housing inlet means adapted to alternately permit and block flow of said expanding gases from said combustion chamber to said power rotor, said valve means including a rotor connected to said power rotor for related motion thereto and having a radial passage the ends of which terminate on opposite sides of said valve rotor, providing communication between said combustion chamber and said power rotor at selected rotational positions of said valve rotor.
