ABSTRACT:
An automatic fuel control valve useful with, rotary, as well as 2-stroke cycle and 4-stroke cycle reciprocating internal combustion engines employs a rubber-like check valve and a porous plug in combination with a chamber for averaging recurrent vacuum pulses from the engine, in which the resulting average pressure is applied to maintain a fuel valve in the open condition while the engine is running and to permit the valve to close when the engine is not running.
