Valve device and system employing same for providing variations in air flow to the manifold of an internal combustion engine in accordance with the engine vacuum. The valve device includes a plurality of resiliently deformable spherical members which are caused to resonate over substantially the full operating range of the engine, whereby the auxiliary air passing through the valve pulsates creating turbulence in the air flow into the manifold resulting in shock waves which assist in breaking up the fuel into smaller, more uniform particle sizes and maintaining a more constant air/fuel mixture over the full operating range. The valve body is in the shape of a Tee having a hollow-cylindrical portion containing the spherical members and oppositely extending tubular arms in communication therewith. One of the arms is plugged, and the other arm is connected to the carburetor by a hard plastic or metal tube which assists in maintaining the air pulsations during passage of the air therethrough. The PCV line extends from the crankcase in communication with the tube, whereby the pulsating air from the valve device imparts pulsations to the air passing through the PCV line thus to maximize the turbulence of air flowing into the carburetor.
In combination with an internal combustion engine having an intake manifold and carburetor, pressure responsive valve means for supplying auxiliary air to said manifold, said valve means comprising a valve chamber having an inlet and an outlet, a plurality of resiliently deformable spherical members within said chamber intermediate said inlet and outlet, said spherical members being positioned within said valve member to resonate over substantially the full operating range of said engine to cause the auxiliary air passing therethrough to pulsate creating turbulence in the air flow entering said manifold resulting in shock waves which assist in breaking up the fuel into smaller, more uniform particle sizes and maintaining a more constant air/fuel mixture over such operating range.
