Abstract
The present invention relates to a cooling apparatus of the combustion chambers for water-cooled engines. When operating a water-cooled engine in inclined condition toward front, the steam gathers in the upper backward of the water-jacket, and this causes overheating. This invention solves above problem by means of providing a steam relief port which is connected with a pressure regulating cap.
Claims6
A cooling system for combustion chambers of a water-cooled engine having a radiator on the front of the engine and a water jacket around the combustion chambers, which cooling system comprises:
- (a) an upper tank and a lower tank carried by the radiator;
- (b) means providing communication between the lower tank and the water jacket for conducting cooling water into the water jacket from the radiator;
- (c) means providing communication between the upper tank and the water jacket for conducting cooling water into the radiator from the water jacket;
- (d) a first port at the upper tank for introducing cooling water therein;
- (e) a first cap for regulating pressure developed in the upper tank;
- (f) a second port at the water jacket at the rear of the engine for releasing steam developed in the upper rear portion of the water jacket;
- (g) a second cap for regulating pressure developed at the upper rear portion of the water jacket;
- and
- (h) a first conduit connected to the second port at its lower end and to the second cap at its upper end for providing communication between the second port and the second cap, wherein the conduit disposes the second cap about the uppermost portion of the water jacket to permit exhausting steam therefrom into the atmosphere through the second cap and preventing damage from overheating during prolonged operation of the engine in an inclined disposition.
