COOLING MECHANISM FOR INTERNAL-COMBUSTION ENGINES.
Application filed October 10, man,
This invention relates to cooling mechanism forsingle and multiple cylinder combustion engines and particularly to engines of the air cooled type.
In engines of the air-cooled type it is quite impossible to satisfactorily cool the enine at and about the exhaust valves and it is a primary-object of my invention toprovide means which will operate by induced suction to draw off the waste heat and to create a circulation of atmospheric air around the valves in time with the order of their operation.
My invention is directed more particularly to aeroplane motors and I have provided an induction device which is adapted to be placed in an air lane or exposed to atmospheric air to serve-as'a collector of such air, the device being coupled with the exhaust manifold and the latter arranged in communication with the stem guide of an exhaust valve so air passing into the induction device will serve to create suction therein with a resulting tendency toward a forced expulsion of the exhaust gas and heat from v the cylinder of an internal combustion engine and from around the exhaust valve.
' In order to best accomplish this object I vhave provided in combination with my in duction device above referred to, a valve wherein is included a means which operates in time with the movements of the valve to admit atmospheric air to be drawn into the exhaust manifold and around the valve so that the latter is maintained in a cool state at practically all times.
7 Another object of the invention is to provide amechanism which will serve to increase the efiiciency of an internal combustion engine by incorporating an induction device in the exhaust line of the engine, the device being also designed whereby it constitutes an eflicient form of mufiier without ressure as is usually encountered rom t e use of various forms of mufflers. D
With the above and other objects in view as the nature of the invention is better understood, the same consists in theimproved construction and novel arrangements ofparts which will hereinafter be fully described and particularly pointed out in the claims.
In the accompanying drawing, has been illustrated, a sin le and preferred form of the invention, it being, however, understood hibited, but
Serial No. 417,297. Renewed December 4, 1926.
that no limitations are necessarily made to the precise structural details therein exthat changes, alterations and modifications within the scope of the claims may be resorted to when desired.
The view is a vertical section through a part of the cylinder of an internal combustion engine showing the applicationof my invention thereto.
In carrying the invention into practice, use is made of an induction device 5 which is substantially of conical formation and provided with .a flared mouth 6 at its large intake end, the walls 7 of the mouth being restricted in the direction of the flared end 8 of the throat 9 of said device 5. The di ameter of the throat 9 increases forwardly and rearwardly respectively from a line drawn vertically through said throat and as from said fice 10 therebetween.- This orifice is in open communication with a surrounding chamber 11 which extends referably for the full length of the said t roat and the same is in communication with an exhaust manifold 12. The rear or restricted end of the said induction device 5 is provided with one or a suitable number of discharge orifices 13.
A, conventionally illustrates a portion of the cylinder of an internal combustion englue and B, the valve of such engine. The said valve is arranged in a casing or chamber C which includes an integral valve stem guide D and a cylindrical cooling member E. The said cooling member is arranged with its walls in spaced relation to the walls of the guide D so that an air circulating space F is formed between such parts. The stem G of the valve B is adapted to be actuated by means of a rocker H of any suitable lwell known construction. Carried by the stem G is a valve cap I which operates over the outer-end of the cylindrical member E so that when the valve B is closed against its seat, the passage way F will be in open communication with the outside atmosphcre. In other words, when the valve B is closed, the valve cap I is lifted from'the said member E so as to uncover the outer end of the said passage way F. The opposite en d of the said passage way F is in communication with the exhaust manifold-12 by means of a lateral connection'J which is secured at K to one end of said manifold.
The induction device may be positioned immediately adjacent to the cylinder A or can be extended to any point therefrom where the intake end 6 of t e device will be operatively arranged for the reception of a draft or current of atmos heric air. As the air enters the mouth 6 an discharges therefrom into the throat 9, suction is induced at constant suction is created in the the orifice 10 and in the and also in the space F around the valve stem guide D. As the valve B is moved in the ordinary working of the engine, a exhaust manifold and atmospheric air is permitted to be drawn into the space F in proper time with the closing of said valve B against its seat. In this manner the exhaust manifold of the engine is provided with means for augmenting or accelerating the dischar e of the exhaust gas and heat therefrom and resh supplies of atmospheric air are permitted to enter the engine in proximity to the exhaust valve so as to retain the same in a comparatively cool state at all times. It will be understood that after the air passes from the throat 9 of the induction device 5 it is free to leave the device by way of the men: tioned orifice 13.
While I have stated use of the invention in connection with an exhaust valve, it is desired that the valve be simply illustrative of a mechanism constituting part of an internal combustion engine and that the in- Vention can be satisfactorily used in combination with any other part of an engine exhaust manifold where a cooling by the same orsimilar at-- mospheric process may lend toward efficiency in the operation of an engine.
.What is claimed as new is 1. The combination with an internal combustion engine including its exhaust manifold and exhaust valve and means for controlling movements of the latter, of a guide member for the stem of the exhaust valve, said guide member having a portion inte- 1,ess,ese
rior of the manifold and a portionexterior of the manifold, the said guide member having an air space opening at one end on to the exterior portion of the member and at its opposite end on to the interior portion thereof, a valve carried by the aforesaid exhaust valve and'movable therewith and with respect to the exterior portion of the ide member so as to respectively cover and um cover said space in movements of the exhaust valve, and means for inducing suction in said manifold, said means comprising a hollow member having an intake end and an exhaust end, a throat section arranged in said member, the walls of the throat section at one end of the latter exfleifiling directly against the walls of said 0 with, the walls of the throat section at the opposite end thereof being in communication with said intake, and an o ening between the ends of said hollow mem r for communication with the exhaust manifold.
2. The combination with an internal combustion engine including its exhaust mam-- fold and exhaust valve and means for controlling movements of the latter, of a guide member for the stem of the exhaust valve, said guide member having a portion interior of the manifold and a portion exterior of themanifold, the said guide member having an air space opening at one end on to the exterior portion of the member and at its opposite end on to the interior portion thereof, a valve carried by the aforesaid exhaust valve and movable therewith and with respect to the exterior portion of the guide member so as to respectively cover and 1111 cover said space in movements of the ex haust valve, and means for inducing suction in said manifold.
In testimony whereof I have aflixed my signature.
