Abstract
Valve device includes a valve chamber containing three spherical members in stacked relation 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. The valve chamber has a main entry orifice and one or more supplemental entry orifices, the size and number of which may be varied to obtain the desired range or spread of frequencies for a particular engine over its entire operating range.
Claims15
A valve device comprising a valve chamber having a main entry orifice and an exit orifice, valve means within said chamber intermediate said main entry orifice and exit orifice responsive to a vacuum at said exit orifice to produce a substantially constant pulsating air flow through said valve, and supplemental entry orifice means communicating with said chamber for imparting a range or spread of frequencies to the pulsating air flow through said valve, said valve means including an imperforate spherical member within said chamber intermediate said exit orifice and said main entry orifice and said supplemental entry orifice means, said supplemental entry orifice means comprising at least one supplemental entry orifice to said chamber, said main entry orifice having a greater diameter than said supplemental entry orifice.
