A diaphragmed air valve system for an automotive engine is provided which is designed for the purpose of keeping intact the shape as well as the mass of an air flow going through it. This diaphragmed air valve system includes a cylindrical air inlet having a valve opening covered by a number of plates of specific type and arrangement. The rate of air flowing into the engine is dictated by the diameter of the valve opening defined by the specific arrangement and type of the plates.

1. A diaphragmed valve system for controlling airflow to an automotive engine intake comprising:a cylindrical air inlet comprising a valve opening for receiving an airflow; and a plurality of plates of specific type and aerodynamic arrangement forming a diaphragm, said plurality of plates pivotable between a first position covering the valve opening blocking airflow to the valve opening and a second position providing access to a center portion of the valve opening and allowing an airflow streamline through the center portion of the valve opening, wherein the airflow rate to the engine is controlled by the size of the opening defined by the plurality of plates, and wherein the airflow through the valve remains intact. 2. The valve system of claim 1 further comprising a first ring and a second ring, wherein each of the plurality of plates is pivotally coupled to the first ring and is pivotally coupled to the second ring, wherein rotation of the first ring relative to the second ring in a first direction causes the plates to move to the first position and rotation of the first ring relative to the second ring in a second direction opposite the first direction causes the plates to move to the second position.3. A valve and engine combination comprising:an engine comprising an intake; a valve controlling airflow into the intake, the valve comprising, a cylindrical air inlet comprising a valve opening for receiving an airflow, and a plurality of plates of specific type and aerodynamic arrangement forming a diaphragm, said plurality of plates pivotable between a first position covering the valve opening blocking airflow to the valve opening and a second position defining an opening providing access to a center portion of the valve opening and allowing an airflow streamline through the center portion of the valve opening, wherein the airflow rate to the engine is controlled by the size of the opening defined by the plurality of plates, and wherein the airflow through the valve remains intact. 4. The combination of claim 3 wherein the valve further comprises a first ring and a second ring, wherein each of the plurality of plates is pivotally coupled to the first ring and is pivotally coupled to the second ring, wherein rotation of the first ring relative to the second ring in a first direction causes the plates to move to the first position and rotation of the first ring relative to the second ring in a second direction opposite the first direction causes the plates to move to the second position.5. A diaphragmed valve system for controlling airflow to an automotive engine intake comprising:a cylindrical air inlet comprising a valve opening for receiving an airflow; a first ring and a second ring; and a plurality of plates of specific type and aerodynamic arrangement forming a diaphragm, each of the plurality of plates is pivotally coupled to the first ring and is pivotally coupled to the second ring, wherein rotation of the first ring relative to the second ring in a first direction causes the plates to move to a first position restricting airflow to the valve opening and rotation of the first ring relative to the second ring in a second direction opposite the first direction causes the plates to move to a second position allowing an airflow streamline through the valve opening. 6. A valve and engine combination comprising:an engine comprising an intake; a valve controlling airflow into the intake, the valve comprising, a cylindrical air inlet comprising a valve opening for receiving an airflow, a first ring and a second ring, and a plurality of plates of specific type and aerodynamic arrangement forming a diaphragm, each of the plurality of plates is pivotally coupled to the first ring and is pivotally coupled to the second ring, wherein rotation of the first ring relative to the second ring in a first direction causes the plates to move to a first position restricting airflow to the valve opening and rotation of the first ring relative to the second ring in a second direction opposite the first direction causes the plates to move to a second position allowing an airflow streamline through the valve opening.
