ABSTRACT:
A valve for flowing gaseous fuel, i.e., natural gas or propane gas, to an internal combustion engine includes a valve body having an inlet passage and first and second outlet paths in parallel with one another and in flow communication with the inlet passage. A plug-type adjustment member is threaded into the body and an annular seat in the body coacts with the adjustment member to form an orifice in the first outlet path. A stop mechanism limits movement of the adjustment member between a first position at which the orifice area is smaller and a second position at which the orifice area is larger. The valve permits adjustment of fuel flow to small engines so that such engines provide maximum power without exceeding applicable emission standards. And the valve is tamper-resistant.
