Title of Invention	"DIAPHRAGMED AIR VALVE DEVICE"
Abstract	A diaphragmed air valve system for automotive engines which is designed for the purpose of keeping intact the shape as well as mass of an air body before and after entering the engine. This diaphragmed air valve system comprises a cylindrical air inlet (2a) and a valve opening (2b) constituted by a number of small plates of specific type and arrangement (2c). The small plates, with their specific type and aerodynamic arrangement, cause the formation of a number of openings in the centre of the air inlet when the valve is opened. The rate of air flowing into the engine is absolutely dictated by the diameter of the valve opening formed by the specific arrangement and type of the small plates.

Background of Invention Automotive technology needs an engine of sound performance and handling. Car speed can be easily set if the fuel within the engine is entirely combusted. Numerous ways have been so far developed to manage the fuel combustion within the engine. Of them, the most common way is to efficiently manage the air entering the combustion chamber.

Technical Field of Invention
This invention relates to a diaphragmed air valve device used to set the air entering an internal combustion engine in such a way so that the shape as well as the mass of the air keeps intact before and after entering the engine.
Background of Invention
Automotive technology needs an engine of sound performance and handling. Car speed can be easily set if the fuel within the engine is entirely combusted. Numerous ways have been so far developed to manage the fuel combustion within the engine. Of them, the most common way is to efficiently manage the air entering the combustion chamber.
Rate of air supplied into the engine is regulated by an air valve whose area of opening outside the engine can be set. In valves of current use, a intact air body is generally broken into two separated bodies once it enters the engine. To make the shape as well as the mass of the air body unchanged, we need a valve whose opening always lies in the centre of the streamline. Opening of this type can be established only by means of diaphragm system.
Brief Description of the Invention:-
Diaphragmed air valve device on automotive engine is designed for the purposes of regulating air supplied into the engine in such a way so that the shape as well the mass of the air body is unchanged before and after entering the engine. An example of air valve of current use is shown in figure 1. This air valve which comprises a cylindrical inlet (la), and a circular opening (lb) is rotatable along the axis perpendicular to circular cross section of the opening. Rate of air flowing into the engine is absolutely dictated by the angle through which the valve opening is opened.
Basic Constructions of the diaphragmed air valve system presently invented is shown in figure-2. This diaphragmed air valve comprises a cylindrical inlet (2a) and a valve opening (2b) constituted by a number of small plates of specific type (2c) and arrangement. When opened the valve opening forms openings in the centre of the streamline. The rate of air flowing into the engine is controlled by the valve diameter formed due to the specific type and arrangement of the small plates (2c) constituting the valve opening.

Detailed Description of the Invention
One way of handling the rotation of automotive engine is to regulate the air supplied into the engine by using a valve attached on the air inlet of the engine. An example of an air valve of current use in automotive engines is shown in figure 1. The air valve comprising a cylindrical inlet (la) and a circular opening (lb) which is rotatable along the axis perpendicular to circular cross section of the opening. Rate of air flowing into the engine is absolutely dictated by the angle through which the valve opening is opened.
Owing to the shape of the air valve of current use (figure 1), the air passing through it will always be broken into two separated flows (fig 3a). Due to losses, the mass of air flowing into the engine is greatly reduced.
Diaphragmed air valve system of present invention is designed for the purposes of setting the airflow in such a way so that the shape as well as the mass of air before and after entering the engine keep intact.
Basic construction of the diaphragmed air valve system presently invented is shown in figure-2. This diaphragmed air valve comprises a cylindrical inlet (2a) and a valve opening (2b) constituted by a number of small plates of specific type (2c) and arrangement which forms opening openings in the centre of the streamline when the valve is opened. The rate of air flowing

into the engine is dictated by the valve diameter formed by the arrangement of the small plates (2c) constitute the valve opening.
Description and drawings disclosed are intended merely as illustration, not as limitation. Modifications are always possible for the people skilled in the art as long as they are still within the scope of the invention.
