Abstract
A system for cooling internal combustion engine pistons comprising an oil pump driven by the engine, jets projecting oil on the pistons, and a control device (2) interposed between the oil pump and the jets, where the control device comprises a valve (14) positioned between an oil inlet pipe (8) connected to the pressurised oil pump and a jet supply pipe (10), where said valve allows the oil to flow out from the pump to the jets when the oil pressure is at least equal to a threshold pressure, and where the device also comprises a solenoid valve (22) capable of causing the valve (14) to close by permitting the pressurised oil to be brought into contact with the closure member (16), in a direction of closure of the valve (14).
