Abstract

PURPOSE: To prevent overheat of an engine by providing a valve which is opened to supply the engine with a cooling water when a temperature of a cylinder head is increased over a specific value.
CONSTITUTION: When an engine is under a light load, a variation of pressure in a crankcase is low so a diaphragm 5 is shifted a little. Thereby, the discharged amount of a pump (a) is minimized. A greater load provides a greater shifting of the diaphragm 5 so the discharged amount of the pump (a) is increased. When the temperature of the engine, that is of a combustion chamber (d), rises up to a specific temperature or more, a bimetal 17 detects the temperature and is subjected to distortion. Associated with distortion, a valve (b) is opened to supply a nozzle (c) with a cooling water.
