Abstract
A diaphragm valve assembly includes a diffusing screen, and a generally spherical lightweight membrane that provides a 360° circular seal. Spring loading enables variable resistance to be placed on the seal to allow the operator to adjust the internal pressures in an engine by metering the intake and exhaust cycles to obtain maximum performance characteristics from the subject engine.
Claims16
A valve comprising:
- a valve body positioned across substantially all of the area of an intake manifold;
- and
- an adjustable spring loaded conically shaped valve diaphragm mounted in said valve body;
- said diaphragm seating along substantially its entire circumference against a portion of said valve body when said diaphragm is in its closed position and said diaphragm being unseated along substantially its entire circumference from said portion of said valve body when said diaphragm is in its open position.
1 more element
A valve assembly for an internal combustion engine comprising:
- a mounting plate having an aperture formed therein, a diffuser screen connected to said mounting plate across substantially the entire area of said aperture;
- a plurality of support braces connected to said mounting plate across said aperture, said support braces forming an intersection at the midpoint of said aperture;
- an adjustable spring loaded shaft connected to said braces at said intersection, a cylindrical valve body connected to said mounting place at the periphery of said aperture;
- and a conical valve diaphragm connected to said adjustable spring loaded shaft mounted within said cylindrical valve body;
- said conical valve diaphragm being movable within said cylindrical valve body between an open position and a closed position, said conical valve diaphragm sealing against a portion of said valve body for substantially the entire circumference of said valve body when said conical valve diaphragm is in said closed position;
- said conical valve diaphragm forming areas of turbulence across its inner and outer surfaces when in said open position.
3 more elements
A valve for an internal combustion engine comprising a valve body having an inlet and an outlet;
- a conical shaped valve diaphragm mounted within said valve body, said conical shaped valve diaphragm having its circular plane end in proximity to said outlet and its opposite end in proximity to said inlet, said conical shaped valve diaphragm causing turbulence to be generated in a fuel/air mixture passing over the outer surface of said conical shaped valve diaphragm at said inlet and additional turbulence to be generated within said conical shaped valve diaphragm and in proximity to said circular plane at said outlet, said turbulence causing a improved mixing of fuel and air passing to said internal combustion engine.
