270 F. 699 | D.C. Cir. | 1921
This interference relates to carbureters for internal combustion engines. There are three counts, as follows:
1. In a carbureter, the combination, with the casing containing the mixing chamber, of an automatic air valve controlling the admission of air to said mixing chamber, co-operating means variably restricting the flow of the liquid fuel, and a dashpot for retarding the opening movement of said valve, permitting the unresisted closing thereof.
2. In a carbureter, the combination, with a casing containing the mixing chamber, of an automatic valve controlling the admission of air to said chamber, a nozzle for discharging liquid fuel into said chamber, a metering pin co-operating with said automatic valve for variably restricting the flow of liquid to increase the same upon the opening of said valve, a dashpot for resisting the sudden opening of said valve, and a valve-controlled by-pass for said dashpot permitting the unresisted closing of said valve.
3. In a carbureter, the combination, with a easing containing the mixing chamber, of an automatic valve controlling the admission of air to said chamber, a nozzle for discharging liquid fuel into said chamber, a piston connected with said valve, a cylinder co-operating with said piston to form a dashpot for resisting the sudden opening of said valve, and a valve-controlled by-pass for said dashpot permitting the unresisted closing of said valve.
Speed was allowed by the Commissioner count 1, and Kirby counts 2 and 3. Both parties appeal.
Believing that the Commissioner is right, his decision is affirmed.
Affirmed.
