Abstract

Abstract A drive shaft for turning wheels of a vehicle or for operating other devices requiring rotary driving motion, has a pair of diametrically opposed compressors non-rotatively mounted upon it and also a dual channeled turbine mounted upon it with a rotor of the turbine keyed to the drive shaft to cause said shaft to turn with said rotor; separate duct means being provided between the two compressors and diametrically opposite points of the turbine's two channels for conducting ignited gas from the compressors to the turbine to drive said rotor and the drive shaft. Each compressor includes a piston, gas intake and exhaust valves, and means for igniting compressed gas in the compressor to charge the ignited gas into the turbine. A single piston cam is keyed to said shaft for operating the pistons of both compressors and two valve cams are keyed to said shaft for opening and closing the intake and exhaust valves of both compressors in timed interrelation with each other and with the reciprocation of the pistons of both compressors.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 193 words
A turbine engine comprising a rotary shaft for driving a related mechanism, a pair of similar compressors mounted diametrically opposite from each other upon said shaft, and a turbine having a rotor fixed to said shaft for rotation therewith and provided with a pair of side-by-side, integral, vaned, annular, gas-receptive channels; each of said compressors comprising a cylinder including a combustion chamber, a piston operative in said cylinder and partially defining said chamber, fuel intake valve means, gas exhaust valve means, ignition means for igniting fuel within said chamber, said pair of compressors including cam means fixed upon said shaft and coacting separately and alternately with said intake valve means of both compressors, with said exhaust valve means of both compressors, and with said pistons of both compressors to reciprocate said pistons; said engine further comprising ducts connecting the combustion chambers of the two compressors separately to diametrically opposite inlets of the two said channels of the turbine, whereby the force of exhaust gases from the combustion chambers of the two compressors is regularly, alternately applied to said turbine rotor at diametrically opposite points thereof to yield smoothe, efficient operation of the engine.
Claim 2
Dependent Claim 193 words
A turbine engine comprising a rotary shaft for driving a related mechanism, a pair of similar compressors mounted diametrically opposite from each other upon said shaft, and a turbine having a rotor fixed to said shaft for rotation therewith and provided with a pair of side-by-side, integral, vaned, annular, gas-receptive channels; each of said compressors comprising a cylinder including a combustion chamber, a piston operative in said cylinder and partially defining said chamber, fuel intake valve means, gas exhaust valve means, ignition means for igniting fuel within said chamber, said pair of compressors including cam means fixed upon said shaft and coacting separately and alternately with said intake valve means of both compressors, with said exhaust valve means of both compressors, and with said pistons of both compressors to reciprocate said pistons; said engine further comprising ducts connecting the combustion chambers of the two compressors separately to diametrically opposite inlets of the two said channels of the turbine, whereby the force of exhaust gases from the combustion chambers of the two compressors is regularly, alternately applied to said turbine rotor at diametrically opposite points thereof to yield smoothe, efficient operation of the engine.
Claim 3
Dependent Claim 42 words
A turbine engine according to claim 1, said two channels of the turbine having parallel side walls constraining gases introduced thereinto to travel in forceful coaction with the vanes of said rotor throughout a major circumferential part of each of the channels.
Claim 4
Dependent Claim 32 words
A turbine engine according to claim 1, said ducts being of approximately uniform gas conductive capacity throughout their entire lengths from said exhaust valve means to the vanes of the turbine's rotor.
