Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
119 words
A supercharger system for use with a heat engine, comprising: a first heat exchanger having a gaseous phase and a refrigerant liquid phase, said gaseous phase being provided so as to supply the engine from a supercharger compressor, and said refrigerant liquid phase being provided so as to cool said gaseous phase and eliminate excessive heat generated by the supercharger compressor; an independent refrigerant liquid pump for providing liquid flow, means controlling said pump as a function of supercharger pressure and having a time delay for providing a functional dephasing; a second heat exchanger for heat exchange between said refrigerant liquid phase of said first heat exchanger and surrounding air; and an expansion chamber for said refrigerant liquid phase.
Claim 2
Dependent Claim
119 words
A supercharger system for use with a heat engine, comprising: a first heat exchanger having a gaseous phase and a refrigerant liquid phase, said gaseous phase being provided so as to supply the engine from a supercharger compressor, and said refrigerant liquid phase being provided so as to cool said gaseous phase and eliminate excessive heat generated by the supercharger compressor; an independent refrigerant liquid pump for providing liquid flow, means controlling said pump as a function of supercharger pressure and having a time delay for providing a functional dephasing; a second heat exchanger for heat exchange between said refrigerant liquid phase of said first heat exchanger and surrounding air; and an expansion chamber for said refrigerant liquid phase.
Claim 3
Dependent Claim
57 words
A supercharger system as defined in claim 1, wherein said first heat exchanger includes a casing provided so as to envelop a cross flow of supercharged gases and the refrigerant liquid, and a system of finned tubes provided in said casing for carrying the refrigerant liquid, said finned tubes being interposed in the stream of supercharged gases.
Claim 4
Dependent Claim
62 words
A supercharger system as defined in claim 2, wherein said casing has an entry port and an exit port for the supercharged gases, and is formed with spacious manifolds connected to each of said ports, said manifolds and ports being connected so as to form angles of at least 90 between said ports and corresponding manifold portions to which they are connected.
