Abstract
An engine lubricating system has a branch passage for supplying oil to spray nozzles targeted against the engine pistons for piston cooling purposes. A tubular valve element is slidably positioned in the main oil passage for controlling the flow of oil into the branch passage in accordance with the need for piston cooling. The tubular valve element is operated by a thermostatic power element in the main passage.
