ABSTRACT:
Valve device includes a valve chamber containing three spherical members of different hardnesses in stacked relation therein, which produce a limited pulsating air flow that is metered in precise amounts at any given time into the fuel/air path of a gasoline powered internal combustion engine to maintain a narrow band air/fuel ratio over substantially all operating modes. The valve chamber has relatively narrow entry and exit orifices in order to increase the velocity of the pulsations generated therein while at the same time reducing the amount of supplemental air flow through the device. The valve seat also has a conical shape to establish line contact with one of the spherical members to assist in obtaining maximum resonation during operation and provide a more positive seal when the engine is not running. The pulsating air from the valve device is preferably introduced into the carburetor beneath the throttle plate in close proximity below the gas idle jets, providing pressure waves therein that produce turbulence substantially throughout the manifold to assist in remixing and atomizing of the fuel and air, whereby substantially equal air/fuel ratio is supplied to every cylinder for better fuel combustion, with consequent increased power, reduced exhaust pollution, and improved fuel economy.
