Description: |
| Abstract:
This invention relates to the regulating means of a gas engine, more especially to the operating gear for the gas valve, there being separate operating gear for the main valve, both however being operated by a single eccentric, as shown; but separate eccentrics may be used.
The object of the invention is to provide a regulating means for gas engines which will insure a good regulation, a constant mixture during gas admission, namely, the constant proportion of the entering air to the entering gas, a minimum of back-fires, and a regulation of gas consumption more nearly proportional to the power the engine is furnishing.
Claims:
1. In a gas engine the combination of a gas valve, automatically controlled means for tripping the valve open at any point of the inlet stroke, and means for tripping the valve shut at a constant point of the same stroke.
2. In a gas engine, a gas-valve, means for spring tripping the valve open and means for spring tripping the valve shut later than, but during the same stroke in which the valve is tripped open.
3. In a gas engine, a gas valve, an automatically regulated trip for opening the valve and a manually regulated trip for closing the valve.
4. In a gas engine, the combination of a main valve, means for operating the valve, a gas valve, and separate operating means for the valve comprising governor controlled means for tripping the valve open at any point of the inlet stroke and means for tripping the valve shut at a constant point of the same stroke.
5. In a gas engine, a main valve, means for operating the valve, a gas valve, and separate operating means for the gas valve comprising automatically regulated means for tripping the valve open and a manually regulated means for tripping the valve shut.
6. In a gas engine, a main valve, means for operating the valve, a mixing valve, a gas valve, and operating means for the gas valve comprising means for tripping the valve open and means for tripping t e valve shut.
7. In a gas engine, a main valve, operating means therefor, a mixing valve, manual adjusting means therefor, a gas valve, and separate operating means therefor comprising automatically regulated means for tripping the valve open and a manually regulated means for tripping the valve shut.
8. In a gas engine, a gas valve, means for tripping the valve open, means for tripping the valve shut, and means for preventing concussion of parts at the end of opening and closing.
9. The combination in an engine, of a valve, means for tripping said valve open, means for tripping said valve shut, and means for simultaneously energizing the said tripping means.
