Abstract
Abstract A turbocharger for internal combustion engines comprising a unidirectional energy converter having a closed, continuous loop passageway containing a plurality of freely-movable, unrestrained bodies which travel around the passageway in one direction only. In one region of the passageway, successive bodies are propelled in one direction around the passageway by exhaust gases from an internal combustion engine. In another region of the passageway, the kinetic energy of the propelled bodies is used to compress a gas, which can be mixed with fuel. This compressed gas is then forced into the cylinders of the internal combustion engine; whereupon the bodies are again propelled around the passageway to repeat the cycle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
Turbocharger apparatus for an internal combustion engine comprising a continuous, closed- loop passageway, a plurality of freely-movable bodies disposed within said passageway, means to introduce exhaust gases from said internal combustion engine into one region of the passageway for propelling said bodies in one direction around the passageway, means to introduce a gas into another region of the passageway for converting at least a portion of the kinetic energy of the propelled bodies into energy in the form of a compressed gas, and means for conducting said compressed gas to the cylinders of said internal combustion engine where it is further compressed by movement of pistons within the cylinders.
Claim 2
Dependent Claim
109 words
Turbocharger apparatus for an internal combustion engine comprising a continuous, closed- loop passageway, a plurality of freely-movable bodies disposed within said passageway, means to introduce exhaust gases from said internal combustion engine into one region of the passageway for propelling said bodies in one direction around the passageway, means to introduce a gas into another region of the passageway for converting at least a portion of the kinetic energy of the propelled bodies into energy in the form of a compressed gas, and means for conducting said compressed gas to the cylinders of said internal combustion engine where it is further compressed by movement of pistons within the cylinders.
Claim 3
Dependent Claim
21 words
The turbocharger apparatus of claim 1 wherein said compressed gas comprises a mixture of air and fuel derived from a carburetor.
Claim 4
Dependent Claim
21 words
The turbocharger apparatus of claim 1 wherein said internal combustion engine is a diesel engine and said compressed gas comprises air.
Claim 5
Dependent Claim
89 words
The turbocharger apparatus of claim 1 wherein said passageway has four ports spaced around its periphery, one of said ports being connected to a source of exhaust gases under pressure from said internal combustion engine, a second of said ports permitting exhaust of said exhaust gases from the passageway after said bodies have been propelled, a third of said ports permitting gas to be drawn into said passageway for compression, and a fourth of said ports acting to convey compressed gas to the cylinders of said internal combustion engine.
Claim 6
Dependent Claim
123 words
Turbocharger apparatus for an internal combustion engine comprising a continuous, closed-loop passageway, a plurality of freely-movable bodies disposed within said passageway, first port means for introducing exhaust gases from said internal combustion engine into said passageway to thereby propel successive ones of the bodies in one direction around the passageway, second port means in the passageway spaced from the first port means in the direction of movement of said bodies for exhausting said exhaust gases from the passageway, third port means spaced from the second port means in the direction of movement of the bodies for introducing air into the passageway, and fourth port means intermediate the first and third port means connecting said passageway to the cylinders of said internal combustion engine.
Claim 7
Dependent Claim
123 words
Turbocharger apparatus for an internal combustion engine comprising a continuous, closed-loop passageway, a plurality of freely-movable bodies disposed within said passageway, first port means for introducing exhaust gases from said internal combustion engine into said passageway to thereby propel successive ones of the bodies in one direction around the passageway, second port means in the passageway spaced from the first port means in the direction of movement of said bodies for exhausting said exhaust gases from the passageway, third port means spaced from the second port means in the direction of movement of the bodies for introducing air into the passageway, and fourth port means intermediate the first and third port means connecting said passageway to the cylinders of said internal combustion engine.
Claim 8
Dependent Claim
21 words
The turbocharger apparatus of claim 5 wherein said third port means is connected to a device for mixing air with fuel.
Claim 9
Dependent Claim
40 words
The turbocharger apparatus of claim 5 wherein said bodies are in abutment in the region of said passageway between said fourth and first port means but are separated by gas pockets as they travel around the remainder of the passageway.
