ABSTRACT:
An oil pan assembly for an automotive vehicle is formed with an oil pan which is divided by a partition wall into a first and a second chamber. Oil is pumped by an oil pump from the first chamber into the engine of the vehicle through a pipe including an oil strainer. The partition wall is provided with a temperature responsive valve which closes when temperature of the oil is below a predetermined level to cut off flow communication between the second chamber and the first chamber. Thus, with the valve closed, all the oil going to the vehicle engine is drawn from the first chamber. When the temperature of the oil rises above a predetermined level, the temperature responsive valve opens thereby permitting oil circulation from the second chamber into the first chamber.
