Abstract
A device for controlling the lubricating oil temperature of a combustion engine having an oil container for the oil supply of the lubricating oil cycle of the combustion engine and an oil catch basin provided for receiving the return flow of the oil. The catch basin has a smaller volume than the oil container and communicates with the oil container by means of a thermostatically controlled valve. An oil pump communicates with the oil container and/or with the oil catch basin depending upon the position of the valve. A suction device is located at an intermediate chamber at the lowest point of the oil catch basin and communicates with the oil catch basin at low temperature by means of the thermostatically controlled valve positioned in the intermediate chamber and communicates with the oil container during operating temperature. The oil catch basin communicates with the oil container by at least one overflow opening and the oil catch basin communicates with the oil container by means of a float valve provided in the oil catch basin and which opens when the oil supply drops off.
