Description: |
| Abstract:
This invention relates to internal combustion engines in which the cylinders are water jacketed. It is generally desirable to regulate the supply of cooling water to the water jacket of such an engine, especially when the steam generated in the water jacket is discharged into the working cylinder.
The regulation of the water supply has been effected usually, heretofore, by afloat maintain the water in the water jacket at a predetermined level. The float valve and its connections necessarily occupy consider able space, which is objectionable in some installations and are usually not practicable when the engine is mounted upon a moving base.
It is therefore the object of the present invention to provide means for regulating the supply of water to the water jacket, which shall occupy but little space-and shall not be affected by the position of the engine cylinder or by movement of the engine. In, accordance with the invention the valve through which the cooling water is admitted i is controlled by a thermostatic device, which is in such relation to the water jacket as to operate to open the valve when the supply of water in the water jacket falls substantially below a predetermined level and to close the valve when the water rises therein substantially above a predetermined level, but is not chamber and does not permit circulation of water or steam through itself.
Claims:
1. The combination of a water jacketed cylinder, means for supplying cooling water thereto, a valve to control the admission of the cooling water and a chambered thermostatic valve controlling device, the chamber communicating with the water level, and closed to prevent circulation through it, the passage of fluid directly between the valve chamber the expansion rod d is a controlling device comprising a chambered shell and an expanding member in said shell and in operative relation to the said valve, in the chamber of the thermostatic device communicating with water jacket at the approximately predetermined water level and being closed to prevent circulation through it, the passage of liquid directly between the valve chamber and the chamber of the thermostatic device being prevented.
3. The combination of a water jacketed cylinder, means for supplying cooling water thereto, a valve to control the admission of the cooling water and a thermostatic valve controlling device comprising a thermostat shell uniting with the water jacket through a nut at approximately the predetermined level of the water in the jacket and an expansion rod secured at one end in said shell and at the other end bearing against the valve to thrust it from its seat as it expands, the thermostat shell being closed to prevent circulation through it and the passage of fluid directly between the interior of the thermostat shell and the fluid chamber being prevented.
4. The combination of a water jacketed cylinder, means for supplying cooling water thereto, a spring seated valve to control the admission of the cooling water and a thermostatic valve controlling device comprising a thermostat shell uniting with the water jacket through a port at approximately the predetermined level of the water in the jacket and an expansion rod secured at one end in said shell and at the other end bearing against the valve to thrust it from its seat as it expands and means to unseat the valve by hand, the thermostat shell being closed to prevent circulation through it and the passage of fluid directly between the interior of the thermostat shell and. the fluid chambering prevented.
