摘要： Noise from fuel returning to a cylinder and from bubbles contained in the returning fuel is reduced by positioning a nozzle with a plurality of penetration holes, each with much less sectional area than a flow sectional area for returning fuel. The nozzle is also equipped with a guide section installed to change the proceeding direction of the fuel passing through the penetration holes and the fuel return valve.

摘要： A fuel metering device for providing a controlled flow of fuel from a fuel outlet port comprising a body portion, having a fuel valve therein adapted to intermittently admit fuel to a fuel chamber. The fuel chamber partly defines a fuel flow path to the fuel port and a fuel dispersing element is provided in the chamber having a conical dividing surface disposed in the fuel path on the upstream side of the fuel port. The fuel dispersing element includes internal air passages extending through same, the air passage means emitting air in the fuel port centrally of the fuel flow path at the fuel outlet port.
