EXTRA-AIR DEVICE FOR INTERNAL-COMBUSTION ENGINES.
Application filed November fl '0 all whom it may concern:
Be it known that I, Euro HARTWIG VVHYTEHEAD, a British subject, residing at Delmore, Transvaal Province, Union of South Africa, have invented certain new and useful lmprovenients in Extra-Air Devices for Internal-Combustion Engines, of which the following is a specification.
The present invention has reference to means for supplying additional air to the induction systems of internal combustion engines.
An object of the invention is to provide means in conjunction with the extra air supply device for visually indicating the degree of vacuum under which the air is admitted.
A further object is to provide in conjunction with a manually adjustable valve for controlling the extra air, a visual indicator which assists in setting or re-setting the valve according to the condition of the engine, the altitude, and other circumstances aifecting the amount of extra air required.
In the accompanying drawing Fig; I is a view from the front of the dash board; and Fig. II is a view at right angles to Fig. I, partly sectioned and showing the engine connection.
2 indicates a socket which is preferably provided with a transverse flange 3 for securing it to the dash board 4. Said socket ends in a tubular stem 5 which extends through the dash board. A pipe 6 connects the stem tothe induction manifold 7 of the engine 8.
The socket 2 is internally threaded, and into it screws an externally threaded hollow sleeve 9. The sleeve 9 may be provided with a raised andmilled edge 10 to facilitate turning it. 11 is a lock nut on the sleeve and 12 packing material between the lock nut and end of the socket for making an air tight joint around the outside of the sleeve.
At the inner end of the sleeve is formed a valve seat 13 with which co-operates a valve 14. The latter may be guided for movement by wings 15 sliding in the bore 16 of the sleeve. The valve is pressed to the seat by a spring 17, which may be seated in a recess 18 in the bottom of the socket.
19 is a vacuum gauge connected by the pipe 20 to any suitable point of the system 4, 1924. Serial No. 747,804.
within the control of th-evalve 14. Said pipe is conveniently connected to the stem 5, the gauge 19 being supported in the flange 3 and so placed that its hand 21 and dial 22 are visible to the driver.
The dial 22 is provided with any ordinary or arbitrary scale 23 with which the hand 21 co-operates.
At low engine speeds the valve 14 remains on its seat 13, but as the engine speed rises and the vacuum in the induction system consequently increases, the valve lifts. Air is thereby admitted through the sleeve 9, the socket 2 and pipe 6 into the induction manifold 7. I
Once the valve 14 has opened, the vacuum in the socket does not vary to any great extent, increased suction at the manifold being met by greater lift of the valve and corresponding increase in the inflow of extra a1r.
By screwing the sleeve 9 into or out of the socket 2 the resistance offered by the spring 17 to the opening of the valve is increased or decreased. The position of the sleeve for the most favourable running of the engine may be determined by trial, and the sleeve fixed in that position by means of the lock nut 11.
Variations of altitude or temperature, or the changes which gradually occur in the mechanical condition of the engine, are met by corresponding adjustments of the sleeve.
The vacuum gauge 19 facilitates such adjustments. Vhen the sleeve has been set for normal running, upon the engine being started and brought up to speed the hand 21 of the gauge moves from zero until the valve lifts, and it remains substantially at the point then reached notwithstanding increased engine speed. lVhatever adjustments of the sleeve are made, are visually indicated by the hand 21; and restoration of the sleeve to the normal position, after the adjustment has been disturbed for any reason, is readily attained by observing the position of the hand.
I claim.
Extra air supplying means for internal combustion engines comprising a base for arrangement on an instrument board and provided with a socket and a duct leading from said socket and arranged for connection to the induction system of an engine,
a vacuum gauge on said base, a duct leading from the gauge to the first named duet, a sleeve threadedly connected to the socket forming an air intake leading to the socket 5 and provided at its inner end with a valve seat, a valve arranged to close said seat, and a spring arranged in the socket and normally closing the valve, the said sleeve being manually adjustable and serving to vary the tension of said spring. 10
In testimony whereof I have hereunto set my hand.
