AIR REGULATING DEVICE FOR INTERNAL COMBUSTION ENGINES Filed March 9, 1929 My NTOE z ATTORNEY Patented Dec. 23, 1930 UNITED srarss ALEXANDER BAL'ASH, or VAUX HALL, NEW JERSEY AIR-REGULATING DEVICE FOR INTERNAL-COMBUSTION ENGINES Application filed March 9,
, c This invention relates to internal combustionengines, and more particularly to devices for automatically regulating the supply of air to such engines. 1 It is customary'to adjust the carburetors of internal combustion enginesso that normally the proper amount of gasoline or other I fuel will be suppliedto accommodate what may be considered heavy loads. For example, the carburetor of an automobile engine 'will be adjusted so that the proper amount of gasoline will be supplied to the engine when the automobile is being driven up a hill. When the automobile is again on the .7 level and the load on the engine is. light, a
very rich mixture of gasoline and air will be supplied to the engine. That is, more gasoline will be supplied than is necessary, and consequently, there is a waste of the gasoline and the automobile is inefficiently operated.
It is a further object of my invention to provide a device which will admit air through the intake manifold of an internal I combustion engine into the cylinders thereof to relieve excessive vacuum created therein as whenthe automobile motor is turning over rapidly when running downhill with a light load, preventing the drawing up of oil into the cylinders and the fouling of the spark plugs. v 7
It is an object of this invention to provide a device for automatically regulating the supply of air to a gasoline engine so that there will be a proper mixture of gasoline and air for all loads.
It is a further object of the invention to provide an automatic air regulating device which may be readily attached to standard automobile engines without material alterations. 7
A further object is the provision of means for visually indicating when the automatic air regulating device is in operation.
5 These and other objects are attained by the and in which:
1929. Serial 1%. 345,850.
Figure 1 represents a longitudinal sectional view of the air regulating'device.
Figure 2 represents a cross-sectionalview taken on line 22 of Figure 1.
Referring to the drawings, the air regulating attachment is shown to include a short pipe 5 which is threaded into an aperture in the intake manifold 4 of an internal combustion engine. The device itself may be mounted on the cowl of an automobile and connected by means of a hose or other suitable means not shown to the manifold. The outer end of the pipe is threaded at 6 to accommodate threads on a hexagonal block 7, the latter having an internal chamber 8 having a frusto-conical upper end to provide the seat 9 for the frusto-conical valve 10.
The valve 10 is fixed to a rod 11 which passes through a passage 8 entering the chamber 8, the rod being spaced from the wall of the passage. A transverse passage 12 in the block opens into the central passage 8. y
The block 7 is surrounded by a casing 13 which is spaced from thewalls of the block, the casing being provided with slots 14, in which are positioned pins 15 fixed to the block, so that'the casing may have a limited telescoping movement relative to the block 7 The interior surface of the upper end of the casing 13 is provided with a boss 16 having an aperture threaded to accommodate a threaded portion of the rod 11, the latter extending beyond the casing and threadedly engaging a lock nut 17 and a knob 18. The casing 13 is normally maintained in a raised position by a compression spring 19 which surrounds the boss 16 and bears against a seat 20 in the upper end of the block 7.
i A rod 21 passes through the block? and supports a contact member 22, which is adapted to be engaged by a resilient contact mem- Inope'ration, air passes through the space between the casing 13 and the block 7 and enters the passage 12, and thence to passage 8,
from which it is led t'o'the' chamber '8, the latter being connected with the intake manifold of theinternal combustion engine. The valve opening may be adjusted by screwing the threaded end of rod 11 in or out of the boss v16, the adjustment beingheldby the lock nut 17. When the automobile engine is operating under .a light load, thethrottle is almost com- I pletely' closed and consequently the suction is very great, with the result that valvelO is 3 drawn down into chamber 8 against the ac- 'tion of compression spring 19 to allow a larger quantity "of air to enter the intake manifold and provide the proper mixture of gasoline and air. Obviously, whenthe valve.
is'drawn down, the casing will be drawn also, since the valve rod 11 is threadedly engaged with the casing. .Vllhen the casing moves down, the projection 26 of insulating material engages the resilient contact member 23:
and presses the latter into engagement with contact member 22 to close the electrical cirregulating the supply of air to the intake cuit through the lamp 2? and cause the latter to light to indicate to the operator that the air regulating device is in operation.
From the above description it will be seen that I have provided a simple device for manifold of a gasoline engine so that the latter may be economlcally and efficiently operatecl.
The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications with! out departing from the general scope herein indicated and denoted in the appended claim.
v gitu'dinal and transverse passages, said block Having thus described my inventiomwhat vl claim new and desire to secure'by Letters Patent is:
An'automatic air regulating/device com prising a block having. c'onnnuni'cating lonhaving a chamber opening into the longitudlnal passage, a valve for closing the opening between the longitudinal passage and the chamber, a ro'd tired to the valve and extending through the longitudinal passage, a casing surrounding the blo.el{. and spaced apart 7 therefrom, said block having slots in its sides a boss on said casing in threaded engagement with an end of the'rod, a spring between the boss and the block to normally maintain the casing in a predetermined position relative to the block, and pinsjprojecting from the block and slidable in the slots in the, casing to limit the movement of the latter.
