Abstract

Abstract An apparatus for transmitting power obtained by converting the exhaust energy of an engine. An exhaust port is connected to an output turbine via a turbine intake port. The turbine drives an output shaft via a fluid compressor, which in turn is connected via an outlet port to an intake port of a rotary piston type expansion engine having an eccentrically rotating triangle shaped rotor with a double jointed trochoidal shaped rotor housing.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 182 words
Apparatus for transmitting power obtained by converting the exhaust energy of a primary engine, the primary engine having a crank shaft and an exhaust passage for passing exhaust gas from the engine, the apparatus comprising: an output turbine having an output shaft and an intake port coupled to said exhaust passage; a compressor mounted on said output shaft of said turbine and including an outlet port; a rotary type engine having a double jointed trochoidal shaped rotor housing, said housing having an expansion chamber with an intake port and an outlet port and a compression chamber, the engine further comprising an eccentrically rotatable generally triangular shaped rotor mounted within the housing and a rotor shaft coupled to the rotor, said outlet port of said compressor being coupled to said intake port of said expansion chamber, said outlet port of said expansion chamber being coupled to said intake port of said output turbine; and power transmitting means connected between the crank shaft of the primary engine and the rotor shaft of the rotary engine whereby auxiliary power is provided to the primary engine.
Claim 2
Dependent Claim 182 words
Apparatus for transmitting power obtained by converting the exhaust energy of a primary engine, the primary engine having a crank shaft and an exhaust passage for passing exhaust gas from the engine, the apparatus comprising: an output turbine having an output shaft and an intake port coupled to said exhaust passage; a compressor mounted on said output shaft of said turbine and including an outlet port; a rotary type engine having a double jointed trochoidal shaped rotor housing, said housing having an expansion chamber with an intake port and an outlet port and a compression chamber, the engine further comprising an eccentrically rotatable generally triangular shaped rotor mounted within the housing and a rotor shaft coupled to the rotor, said outlet port of said compressor being coupled to said intake port of said expansion chamber, said outlet port of said expansion chamber being coupled to said intake port of said output turbine; and power transmitting means connected between the crank shaft of the primary engine and the rotor shaft of the rotary engine whereby auxiliary power is provided to the primary engine.
Claim 3
Dependent Claim 47 words
Apparatus according to claim 1 wherein said compression chamber has an intake port and an outlet port, said intake port being coupled to the atmosphere and said oulet port being coupled to an intake port of said primary engine to assist the output of the primary engine.
