The instant invention attempts to overcome deficiencies of the prior art by 
providing for enhanced engine combustion efficiency by providing for a 
swirling and distribution of combustion gases directed into the combustion 
chamber of an associated internal combustion engine and in this respect, 
the present invention substantially fulfills this need. 
SUMMARY OF THE INVENTION 
In view of the foregoing disadvantages inherent in the known types of 
engine valve structure now present in the prior art, the present invention 
provides an engine valve wherein the same employs a valve head having a 
helical swirling top wall. As such, the general purpose of the present 
invention, which will be described subsequently in greater detail, is to 
provide a new and improved engine valve which has all the advantages of 
the prior art engine valve structure and none of the disadvantages. 
To attain this, the present invention provides an engine valve including a 
valve head having a helical top wall arranged to enhance turbulence in an 
associated combustion chamber to an internal combustion engine to enhance 
mixing and effective efficiency during the combustion procedure. 
My invention resides not in any one of these features per se, but rather in 
the particular combination of all of them herein disclosed and claimed and 
it is distinguished from the prior art in this particular combination of 
all of its structures for the functions specified. 
There has thus been outlined, rather broadly, the more important features 
of the invention in order that the detailed description thereof that 
follows may be better understood, and in order that the present 
contribution to the art may be better appreciated. There are, of course, 
additional features of the invention that will be described hereinafter 
and which will form the subject matter of the claims appended hereto. 
Those skilled in the art will appreciate that the conception, upon which 
this disclosure is based, may readily be utilized as a basis for the 
designing of other structures, methods and systems for carrying out the 
several purposes of the present invention. It is important, therefore, 
that the claims be regarded as including such equivalent constructions 
insofar as they do not depart from the spirit and scope of the present 
invention. 
Further, the purpose of the foregoing abstract is to enable the U.S. Patent 
and Trademark Office and the public generally, and especially the 
scientists, engineers and practitioners in the art who are not familiar 
with patent or legal terms or phraseology, to determine quickly from a 
cursory inspection the nature and essence of the technical disclosure of 
the application. The abstract is neither intended to define the invention 
of the application, which is measured by the claims, nor is it intended to 
be limiting as to the scope of the invention in any way. 
It is therefore an object of the present invention to provide a new and 
improved engine valve which has all the advantages of the prior art engine 
valve structure and none of the disadvantages. 
It is another object of the present invention to provide a new and improved 
engine valve which may be easily and efficiently manufactured and 
marketed. 
It is a further object of the present invention to provide a new and 
improved engine valve which is of a durable and reliable construction. 
An even further object of the present invention is to provide a new and 
improved engine valve which is susceptible of a low cost of manufacture 
with regard to both materials and labor, and which accordingly is then 
susceptible of low prices of sale to the consuming public, thereby making 
such engine valves economically available to the buying public. 
Still yet another object of the present invention is to provide a new and 
improved engine valve which provides in the apparatuses and methods of the 
prior art some of the advantages thereof, while simultaneously overcoming 
some of the disadvantages normally associated therewith. 
These together with other objects of the invention, along with the various 
features of novelty which characterize the invention, are pointed out with 
particularity in the claims annexed to and forming a part of this 
disclosure. For a better understanding of the invention, its operating 
advantages and the specific objects attained by its uses, reference should 
be had to the accompanying drawings and descriptive matter in which there 
is illustrated preferred embodiments of the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
With reference now to the drawings, and in particular to FIGS. 1 to 10 
thereof, a new and improved engine valve embodying the principles and 
concepts of the present invention and generally designated by the 
reference numeral 10 will be described. 
More specifically, the engine valve 10 of the instant invention essentially 
comprises a valve stem 11 fixedly and orthogonally mounted to a valve head 
12. The valve head includes a valve head bottom wall 13 arranged in a 
facing relationship relative to a combustion chamber of an internal 
combustion engine, in a manner as indicated in U.S. Pat. No. 4,805,573 
incorporated herein by reference. The valve head 12 includes a valve head 
top wall 15 having a helical configuration, including a top wall first end 
16 arranged in contiguous communication with a conical side wall portion 
14 of the valve head 12. The top wall includes a top wall second end 17 
radially directed to the valve stem 11 arranged in a spaced relationship 
to the valve head 12. The top wall structure in this manner provides for 
enhanced swirling of combustion charges directed into and out of the 
associated internal combustion engine. Particularly, intake charges are 
swirled in the upper projection of the internal combustion chamber for 
enhanced combustion efficiency. 
The FIG. 3 indicates the top wall 15 including a peripheral top wall outer 
rib 18 extending from the conical side wall portion 14 with the top wall 
first end 16 to the top wall second end 17, with the rib 18 arranged 
concentrically relative to the stem 11. 
The FIGS. 5 and 6 indicates the additional employment of ramp plates 19 
integrally mounted to the top wall 15 extending above the top wall. Each 
of the ramps 19 include a ramp front wall 20 orthogonally oriented 
relative to the top wall 15, and a ramp plate top wall canted from the 
ramp wall 20 to the valve head top wall 15. The ramps 19 are radially 
directed along the top wall 15 to and in a spaced relationship relative 
the stem 11 to provide for enhanced swirling and agitation of a charge of 
fuel directed along the top wall. Further to enhance such swirling or even 
greater efficiency if desired, each of the ramps are arranged to 
optionally employ a front wall conduit 21 directed from the front wall 20 
projecting through the ramp top wall 23, with each of the conduits 
arranged to include a plurality of conduit baffle flanges 22 therewithin. 
The FIGS. 9 and 10 provide for an optional structure of the valve head top 
wall to include opposed helical ramp top walls 24, each including a top 
wall first end 16 at opposed sides of the stem 11. 
As to the manner of usage and operation of the instant invention, the same 
should be apparent from the above disclosure, and accordingly no further 
discussion relative to the manner of usage and operation of the instant 
invention shall be provided. 
With respect to the above description then, it is to be realized that the 
optimum dimensional relationships for the parts of the invention, to 
include variations in size, materials, shape, form, function and manner of 
operation, assembly and use, are deemed readily apparent and obvious to 
one skilled in the art, and all equivalent relationships to those 
illustrated in the drawings and described in the specification are 
intended to be encompassed by the present invention. 
Therefore, the foregoing is considered as illustrative only of the 
principles of the invention. Further, since numerous modifications and 
changes will readily occur to those skilled in the art, it is not desired 
to limit the invention to the exact construction and operation shown and 
described, and accordingly, all suitable modifications and equivalents may 
be resorted to, falling within the scope of the invention.
