Abstract

A fuel regulator is provided for regulating the supply of fuel to a multi-cylinder engine. The regulator includes a regulator body defining a holding chamber connectable to a fuel source; a first supply chamber connectable to a first cylinder of the multi-cylinder engine; and a second supply chamber connectable to a second cylinder of the multi-cylinder engine. Orifices are provided between the supply chambers and the holding chamber. A first regulating structure is movable between a closed position wherein the orifice between the holding chamber and the first supply chamber is closed and an open position wherein the orifice between the holding chamber and the supply chamber is open in response to the fuel demanded by the first cylinder of the multi-cylinder engine. A second regulating structure is also movable between a closed position wherein the orifice between the holding chamber and the second supply chamber is closed and an open position wherein the orifice between the holding chamber and the second supply chamber is opened in response to the fuel demanded by the second cylinder of the engine.
