Description: |
| Abstract:
This invention pertains to internal combustion engines, more particularly to the fuel feeding regulating means therefor, and has for its purpose to further improve on that general type of fuel feeder shown in the patent granted to Joseph Reid, No. 607,276, dated July 12, 1898.
This type of fuel feeder embodies in its structure a supply cylinder adapted to receive charges of air and gas, which charges after commingling are delivered to the explosive chamber of the engine. To properly proportion these charges of air and gas it is necessary that their respective inlet valves vary in dimension corresponding to the proportions of mixture required, and to accomplish which the gas intake valve is of considerably less dimension than the valve of the air intake. To have these valves in proper working condition there must necessarily be some difference between the diameters of the valves proper and the holes in which they operate, and thus when substantially in closed position there must necessarily be slight spaces through which the elements of combustion leak into the mixing chamber by reason of the vacuum created in the pumping or supply cylinder. Owing to the fact that the leakage through the gas valve is not in the same proportion as the leakage of the air valve, as the gas is to the air in the charge, the mixture occasioned by said-leakage is improportionate in that it contains a greater proportionate amount of gas than air, and with the increase in suction there is a corresponding increase in the excess of gas in the mixture. The vacuum produced in the charge forming cylinder has a retarding effect on the engine and there is the further fault of a tendency to back firing. In overcoming these defects this invention embodies the idea of providing means whereby a constant charge, or proportionate excess of air to gas, is admitted to the mixing chamber whereby to neutralize the normal excess of gas above referred to.
Claims:
1. In a fuel feeder controller for explosive engines, the combination with a casing having a mixing chamber, of valves operable within said easing and admitting air and gas to the mixing chamber, said air valve provided with slots in one of its marginal edges, said slots adapted to constantly register with the mixing chamber, and means for proportionately varying the admission openings of said valves.
2. In a fuel feeder controller for explosive engines, the combination with a casing having a mixing chamber, of valves operable within said casing and admitting air and gas to the mixing chamber, said valves arranged in parallel, said air valve provided with slots in one of its marginal edges, said slots adapted to constantly register with the mixing chamber, and means for proportionately varying the admission openings of said valves.
3. In a fuel feeder controller for explosive engines, the combination with a casing having a mixing chamber, of valves adapted to reciprocate within said casing and admit air and gas to the mixing chamber, said valves being of substantially cylindrical tubular structure and disposed in parallel, outlet openings in said valves adapted to register with the mixing chamber, said air valve having slots cut therein immediately adjacent its outlet opening, said slots adapted to constantly register with the mixing chamber whereby air is continuously admitted thereto, and means for proportionately varying the position of said valves.
