Abstract
Abstract A control system for internal combustion engines adapted to take in ambient air and mix it with waste gases from a crankcase to form a molecular comburent mixture to aid in combustion. The system includes a housing mounted between the crankcase and the engine manifold that both forms the comburent mixture and regulates the introduction of the same into the engine manifold.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
184 words
In a control system for use in internal combustion engines, having a crankcase and having an intake manifold, comprising: a main body having a throughbore therein offset from the central axis thereof; an inlet leading into the interior of said throughbore, said inlet being connected to the crankcase; an outlet in fluid communication with the interior of said throughbore, said outlet being connected to the intake manifold; a shaft mounted for rotation in said bore; a turbine having a plurality of blades thereon keyed to said shaft for rotation therewith, said turbine having turbine rotating means disposed in a position wherein fluids entering said throughbore from said inlet impel on said turbine rotating means thereby rotating said turbine; and spring biased ambient air valve means mounted at the top of said main body having an inlet communicating with the interior of said throughbore with a spring biased ball mounted in said inlet adapted, in a first position, to admit ambient air into the interior of said throughbore and, in a second position, prevent any fluids in said throughbore from exiting out of said inlet.
Claim 2
Dependent Claim
184 words
In a control system for use in internal combustion engines, having a crankcase and having an intake manifold, comprising: a main body having a throughbore therein offset from the central axis thereof; an inlet leading into the interior of said throughbore, said inlet being connected to the crankcase; an outlet in fluid communication with the interior of said throughbore, said outlet being connected to the intake manifold; a shaft mounted for rotation in said bore; a turbine having a plurality of blades thereon keyed to said shaft for rotation therewith, said turbine having turbine rotating means disposed in a position wherein fluids entering said throughbore from said inlet impel on said turbine rotating means thereby rotating said turbine; and spring biased ambient air valve means mounted at the top of said main body having an inlet communicating with the interior of said throughbore with a spring biased ball mounted in said inlet adapted, in a first position, to admit ambient air into the interior of said throughbore and, in a second position, prevent any fluids in said throughbore from exiting out of said inlet.
Claim 3
Dependent Claim
55 words
In the system of claim 1 wherein said inlet includes a first passageway extending normal to the central axis of said main body communicating with a second passageway offset from said central axis of said main body but parallel thereto communicating at the bottom with a third passageway opening into the interior of said throughbore.
Claim 4
Dependent Claim
42 words
In the system of claim 1 wherein said outlet includes a passageway extending normal to the central axis of said body communicating with the interior of said throughbore, the diameter of said passageway being substantially greater than the diameter of said inlet.
Claim 5
Dependent Claim
71 words
In the system of claim 1 wherein said body is closed off at the bottom by an end cap, said end cap having a boss thereon closing off the bottom of said throughbore, said impeller having a first ball bearing mounted in an opening in said boss with a knurled shaft extending upwardly therefrom having its upper end mounted in a second ball bearing, said turbine being keyed to said shaft.
Claim 6
Dependent Claim
32 words
In the system of claim 1 wherein said turbine includes a base mounted on said shaft, said turbine rotating means including a plurality of peripheral slots about the base of said turbine.
Claim 7
Dependent Claim
33 words
In the system of claim 1 wherein said body is closed off at the top by a thermal cap having a plurality of spaced elongated ribs forming air channels in the top thereof.
Claim 8
Dependent Claim
27 words
In the system of claim 6 wherein said thermal cap includes a plurality of spaced cavities on the underside thereof communicating with the interior of said throughbore.
Claim 9
Dependent Claim
94 words
In the system of claim 6 wherein said thermal cap includes an opening therethrough axially aligned with the central axis of said throughbore and in fluid communication therewith, said air valve means including an inlet housing mounted in said opening having an axial throughbore communicating at the top with the exterior of said thermal cap and at the bottom with the interior of said body throughbore, a passageway in said inlet housing at the bottom thereof extendng normal to said inlet housing axial throughbore and also communicating with the interior of said body throughbore.
Claim 10
Dependent Claim
78 words
In the system of claim 8 wherein said inlet housing includes a shoulder in the interior thereof above the intersection of said inlet housing throughbore and said passageway through said inlet housing, a resilient ball return spring mounted in said inlet housing on said shoulder, said ball being mounted on the top of said spring, said inlet housing being closed off at the top by an apertured cap providing a seat for said ball on the undersurface thereof.
Claim 11
Dependent Claim
107 words
In the system of claim 9 wherein said inlet housing has a cavity in the bottom thereof below the intersection of said inlet housing throughbore and said passageway therethrough, said body being closed off at the bottom by an end cap, said end cap having a boss thereon closing off the bottom of said throughbore, said shaft having a first ball bearing mountd in an opening in said boss with a knurled shaft extending upwardly therefrom and having its upper end mounted in a second ball bearing mounted in said cavity in said inlet housing, said turbine being mounted on said shaft and keyed for rotation therewith.
