Abstract
Abstract The open air intake end of a hollow housing has adjustable air control shutters to regulate intake air to the transonic rotary vane component of an air compressor. The high velocity air output from the rotor is straightened to axial flow by passage through a stator vane component of the compressor at which combustion fuel is metered to the high velocity air. The fuel-air mixture then is expanded into a collector chamber from whence it is delivered to the intake valve system of an internal combustion engine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A supercharger and fuel injector assembly for an internal combustion engine having a plurality of cylinders, comprising: a. a hollow housing having an open air inlet at one end and a fuel-air mixture collector at the opposite end; b. an air compressor rotor in the housing for compressing inlet air and moving it toward the collector; c. drive means engaging the rotor for rotating the latter; d. an air compressor stator in the housing downstream of the rotor for minimizing the swirl of compressed air flow to the diffuser; e. fuel inlet means at the stator for introducing combustion fuel into the compressed air; f. diffuser means in the housing converging in the downstream direction from the stator for expanding the fuel-air mixture and slowing its movement toward the collector; and g. means for communicating the collector with said cylinders.
Claim 2
Dependent Claim
140 words
A supercharger and fuel injector assembly for an internal combustion engine having a plurality of cylinders, comprising: a. a hollow housing having an open air inlet at one end and a fuel-air mixture collector at the opposite end; b. an air compressor rotor in the housing for compressing inlet air and moving it toward the collector; c. drive means engaging the rotor for rotating the latter; d. an air compressor stator in the housing downstream of the rotor for minimizing the swirl of compressed air flow to the diffuser; e. fuel inlet means at the stator for introducing combustion fuel into the compressed air; f. diffuser means in the housing converging in the downstream direction from the stator for expanding the fuel-air mixture and slowing its movement toward the collector; and g. means for communicating the collector with said cylinders.
Claim 3
Dependent Claim
19 words
The assembly of claim 1 wherein the drive means is operable to rotate the rotor at transonic relative velocities.
Claim 4
Dependent Claim
20 words
The assembly of claim 1 including adjustable means at the inlet end of the housing for varying the opening thereof.
Claim 5
Dependent Claim
57 words
The assembly of claim 1 wherein the stator comprises a plurality of circumferentially spaced radial vanes, and the fuel inlet means comprises: h. an annular fuel distributor chamber; i. means communicating the fuel distributor chamber with a source of fuel; and j. circumferentially spaced passageway means communicating the fuel distributor chamber with the spaces between stator vanes.
Claim 6
Dependent Claim
50 words
The assembly of claim 4 wherein the passageway means extend radially outward through at least some of the stator vanes for communication at their outer ends with the fuel distributor chamber, and transverse ports in said stator vanes communicate the fuel passageway means with the air spaces between said vanes.
Claim 7
Dependent Claim
40 words
The assembly of claim 5 wherein the stator vanes have an air foil cross-sectional shape and the transverse ports communicating the fuel passageway with the suction side of the vanes are directed angularly outward in the direction of air travel.
Claim 8
Dependent Claim
30 words
The assembly of claim 6 wherein the transverse ports communicating the fuel passageway with the pressure side of the vanes are directed substantially normal to the direction of air travel.
Claim 9
Dependent Claim
77 words
The assembly of claim 4 wherein the means communicating the fuel distributor chamber with a source of fuel comprises: k. a fuel inlet chambEr communicating with the fuel distributor chamber; l. control valve means communicating the fuel inlet chamber with a source of fuel; and m. float means in the fuel inlet chamber engaging the control valve means and operable to close the latter when the level of fuel in the inlet chamber reaches a predetermined maximum.
Claim 10
Dependent Claim
25 words
The assembly of claim 8 including air passage means communicating the fuel inlet chamber above said fuel level with the inlet opening in the housing.
